High blood pressure and how it affects your heart rate
Date: March 9th, 2024
In most cases, high blood pressure and heart rate go hand in hand, and you want to ensure they’re just right. And it would help if you struck a balance between the two extremes for your cardiovascular system’s health.
Besides, there is often a correlation between high blood pressure and a rapid heartbeat. However, some hypertensives have unusually slow pulse rates. Even though the two statements seem at odds with one another, it’s usually because of something else or an underlying concern that might or might not be a health issue.
This article discusses the causes of hypertension without a corresponding increase in heart rate and the connection between the two. Furthermore, it discusses the circumstances under which high blood pressure and heart rate might cause concern and warrant a visit to the doctor. However, maintaining optimal cardiovascular health is feasible under any circumstances.
Understanding High blood pressure
High blood pressure or hypertension is a frequent medical issue and a primary contributor to cardiovascular and stroke-related illnesses.
When the heart rate is high, the blood pressure is also high, raising the likelihood of hypertension and, in the hypertensive population, increasing the risk of cardiovascular disease. Despite these correlations, antihypertensive drug selection typically does not take heart rate into significant account.
Therefore, the force of a person’s blood pushing against their blood vessel walls is their blood pressure. The amount of effort the heart must exert and the stiffness of the blood arteries are the two main factors determining blood pressure.
About half of all U.S. adults have elevated blood pressure, which may be an underestimation. This condition can result in several cardiovascular complications like aneurysm, heart failure, and stroke. Blood pressure must be controlled to maintain health and reduce the likelihood of these potentially fatal disorders.
What are the causes of blood pressure?
In many cases, doctors can’t pin down what exactly triggers someone’s hypertension. It usually occurs as a secondary effect of something else. It’s called essential or primary hypertension if it does not result from another medical issue.
However, high blood pressure is referred to as secondary hypertension when an underlying ailment is the root cause of hypertension.

Several causes can lead to primary hypertension.
- Salty diet
- Smoking
- Being overweight
- Low insulin sensitivity
- Excess alcohol consumption
- Leading a sedentary livelihood
You may experience secondary hypertension due to some health conditions like:
- Diabetes
- Obesity
- Pregnancy
- Kidney disease and infections
- Restriction of blood flow in the arteries that supply the kidneys
- Kidney disease, known as glomerulonephritis, causes inflammation of the kidney’s microscopic filtration units.
- Sleep apnea is caused by obstruction of the airway that happens when the throat muscles relax and close during sleep, preventing easy breathing.
- Hormonal imbalances or problems include but are not limited to hypothyroidism, hyperaldosteronism, hyperthyroidism, phaeochromocytoma, Cushing’s syndrome, and acromegaly.
- Lupus: This is a medical disease in which your immune system mistakenly targets healthy tissues and attacks various parts of the body.
- Scleroderma is a disease characterized by skin thickening and, sometimes, complications involving internal blood vessels and organ vessels.
You may also experience hypertension due to certain medications like:
- Contraceptive
- Steroids
- Drugs used for recreational activities like cocaine and amphetamines.
- Medicinal plants, especially licorice-based herbal supplements
<h2>What factors increase your likelihood of high blood pressure?<h2>
Hypertension has several risk factors, including:
Overweight and obesity
Alterations to the kidneys and blood arteries are among the many effects of being overweight. These shifts typically result in elevated blood pressure, primarily since they are associated with high cholesterol.
Use of nicotine products or electronic nicotine delivery systems
If you want a quick and temporary boost to your blood pressure, try smoking, chewing tobacco, or vaping. Cigarette smoke damages coronary arteries and hastens atherosclerosis. Don’t hesitate to consult your doctor or other healthcare professional for advice on how to quit smoking.
Severely deficient potassium levels
Potassium maintains a healthy intracellular salt balance. Keeping your potassium levels in check can do wonders for your ticker. Potassium deficiency can result from insufficient minerals in one’s diet or medical problems like dehydration.
Stress
A transitory rise in blood pressure has been linked to prolonged high-stress levels exposure. In addition to the direct effects of stress itself, the development of bad habits like binge eating, smoking, and excessive alcohol use can amplify the rise in blood pressure.
Other factors that increase your risk include:
- Chronic or persistent diseases: There are many causes of hypertension, including kidney illness, diabetes, and sleep apnea.
- Inactivity: The lack of exercise might lead to weight gain. The risk of hypertension increases with body mass index. Inactive people also typically have more excellent heart rates.
- Age: The probability of developing hypertension rises as one gets older. Men are more likely to suffer from high blood pressure than women before age 64. After age 65, women are more susceptible to developing hypertension than men.
- Family history: If either of your parents or siblings has high blood pressure, you are more likely to get the illness yourself.
- Race: African-Americans have a disproportionately high rate of high blood pressure. African-Americans typically show signs of it earlier than their white counterparts.
Adults tend to be the population with the highest rates of hypertension. However, hypertension can also affect children. Conditions affecting the kidneys or the heart can also trigger high blood pressure in youngsters. However, unhealthy lifestyle choices like poor eating and insufficient physical activity are to blame for high blood pressure in an increasing proportion of children.
So, how can you know you have high blood pressure?
Symptoms of high blood pressure
Hypertension is sometimes referred to as a “silent killer” because its victims may not experience noticeable symptoms. Heart, blood vessels, and organ damage, including the kidneys, can result from undiagnosed hypertension. Therefore, periodic blood pressure monitoring is essential.
However, here are some of the symptoms of high pressure you need to watch out for:
- Sleeping problems
- Sweating
- Blushing
- Anxiety
However, you may only see these symptoms in highly unusual and dire circumstances, but in most cases, a person with high blood would not show signs. Unfortunately, others with hypertensive crises often complain of nosebleeds and sometimes headaches.
Complications of high blood pressure
High blood pressure, which causes the artery walls to bear an abnormally large force, can harm blood vessel health and organ function. The more severe the consequences of hypertension, the longer it remains untreated.
In addition to these potential side effects of unchecked hypertension, there is also the risk of Stroke or heart attack.
- Heart failure
- Kidney problems
- Dementia
- Aneurysm
- Eye concerns
- Metabolism syndrome
So, what’s the link between high blood pressure and heart rate ?
Blood pressure and heart rate or pulse
Your doctor may take your blood pressure and heart rate to check your cardiovascular and general health. Despite their similarities, these indicators of health might provide vastly diverse insights.
The frequency with which your heart contracts and relaxes is your pulse or heart rate. An average pulse rate is somewhere from 60 – 100 bpm.

Your hypertension is an approximation of the pressure your blood is putting on your arteries. The standard blood pressure reading is 120 over 80. Suppose your systolic (upper) blood pressure is 130 mm Hg or higher, and your diastolic (lower) blood pressure is 80 mm Hg or higher. In that case, your doctor will likely diagnose you with hypertension (the bottom number).
If your pulse is less than 60 beats per minute, you have high blood pressure, which indicates that your blood is exerting added stress on your blood vessels.
What’s the relationship between high blood pressure and heart rate, especially low pulse?
The relationship between your blood pressure and heart rate can be understood by comparing the two to an electricity supply and a plumbing system.
Electrical impulses are primarily responsible for regulating your heart rate. They send signals to your heart’s chambers, instructing them to beat in unison. Your heart rate can increase due to physical exertion, emotional stress, or terror. Sitting around all day can hinder its progress.
To get your heart’s plumbing system moving, it uses this electrical system to stimulate a pumping motion. Blood flows without difficulty when the “systems,” or circulatory system, are unobstructed. For the heart to successfully pump blood through constricted arteries, it must contract more forcefully or beat faster. The end outcome is elevated blood pressure.
Cardiovascular stress occurs when blood pressure and heart rate are not expected. You could be experiencing a variety of symptoms, such as:
- Tiredness and difficulty breathing
- Confusion and trouble exercising
- Weakness and dizziness
In some cases, high blood pressure and heart rate could cause cardiac arrest.
Causes of elevated blood pressure and slow heart rate
Numerous factors can contribute to both hypertension and a slow heart rate.
Thickened cardiac muscle: In rare cases, the decreased pulse rate may result from years of hypertension. The heart’s tissues may change shape if your blood pressure is consistently high. Tissues may thicken in an effort to generate more force, for instance.
Electrical impulses have a more difficult time penetrating this thicker tissue. Since electrical impulses take more time to travel, your heart rate may gradually decrease.
Medication for high blood pressure: Medications used to treat hypertension, such as calcium channel blockers or beta-blockers, have been linked to a decreased pulse rate in some patients. These drugs lessen the frequency of your heartbeat, making the heart’s job easier and lowering your blood pressure.
Major bleeding or traumatic injury: Hypertension and a slow heart rate might be symptoms of head trauma and bleeding around the brain. The Cushing response occurs when there is a rise in cerebral pressure due to injury or bleeding.
Cushing reflex symptoms include:
- Moderately slow pulse
- Arterial hypertension
- Unusually slow or erratic breathing
Should you be worried if your blood pressure is high, but the pulse is slow?
As long as your pulse rate is low, having slightly elevated blood pressure while taking hypertension medication is usually not cause for alarm.
However, if you are not currently medicated, it is recommended that you consult a medical professional to determine the cause of your symptoms. If you feel faint or short of breath, you may have a low pulse and should take this warning seriously.
For most people, the optimal heart rate to circulate sufficient blood throughout the body is somewhere between 60 and 100 bpm, which is also the average range for measuring the pulse.
The pulse rate of some persons may naturally be lower than average. Athletes and other people in peak physical condition are prime examples. They’ve built up their cardiovascular endurance through training. The improved pumping efficiency of their heart reduces the frequency with which it needs to beat.
How lower high blood pressure and heart rate
The risk of a heart attack or stroke and the severity of hypertension will play a role in determining the best course of treatment.
If your doctor notices a rise in your hypertension, they may prescribe an alternative course. If your blood pressure is slightly elevated, your doctor may recommend making some lifestyle modifications and keeping a close eye on your readings.
Doctors might also prescribe medication if your blood pressure is too high. Depending on the progression of hypertension as well as the presence or absence of comorbidities such as kidney disease, the treatment options may shift over time. Some patients may require a cocktail of treatments.
Medications
Commonly used pharmaceuticals to treat hypertension are:
Angiotensin-converting enzyme blockers: Inhibitors of the enzyme angiotensin converting (ACE) reduce blood pressure by preventing the production of angiotensin II and other hormones that raise it. Increased blood pressure results from angiotensin II’s ability to narrow vessels and boost blood volume.
However, ACE inhibitors can decrease blood flow to the kidneys, thus decreasing their efficiency. This necessitates routine blood monitoring for those who take these medications.
Pregnant people with a disorder that reduces blood flow to the kidneys should also avoid taking ACE inhibitors. The following are some of the possible adverse effects of ACE inhibitors; however, most people find that these go away after some days:
- Fatigue and dizziness
- Weakness and headaches
- A persistent dry hacking cough
Thiazide diuretics: To reduce blood volume and pressure, thiazide diuretics aid the kidneys in excreting sodium and water.
Some of the following may occur due to taking them. It may even persist: Reduced potassium in the blood can lead to issues like heart and kidney failure, decreased glucose sensitivity, and erection dysfunction.
Calcium channel blockers: CCBs are drugs used to lower blood calcium levels. Smooth muscle vascular relaxation means less violent muscular contractions, wider arteries, and lower blood pressure.
However, CCBs aren’t always safe for everyone because of the risks associated with cardiovascular illness, liver disease, and poor blood flow. You should discuss the usage of CCBs and which is appropriate with your doctor.
CCBs have the potential to cause the following side effects; however, they often disappear within a few days:
- Headaches
- Foot and ankle swelling
- A state of skin redness, most noticeable on the face and neck.
- Dizziness and fatigue
Beta-blockers: Although beta-blockers were historically widely used to treat hypertension, modern medicine often reserves its prescription for patients whose blood pressure has not responded to other medications. These drugs lower blood pressure by decreasing heart rate and cardiac output.
These medications may, however, cause slow heartbeat, nausea, diarrhea, and fatigue.
Proper Nutrition
By making healthy food choices, you can regain your health, and by keeping your blood pressure in check, you can avoid medication. To achieve this, you must:
- Eat more vegetables and fruits
A healthy diet may include taking fruits, omega oils, vegetables, and high-quality, unprocessed carb sources like whole grains are all part of a healthy, well-balanced diet. Vegans and vegetarians should eat lean meat cuts and avoid processed foods.
- Consuming less salt
To control or avoid high blood pressure, experts advise reducing salt and upping potassium intake. Those with hypertension may benefit from reducing their salt intake to less than 5-6 grams daily, which has been shown to lower systolic blood pressure.
- Consider the DASH eating plan.
According to experts, people with hypertension can significantly benefit from dietary approaches to stop hypertension. This eating plan stresses a diet high in fiber from vegetables, whole grains, fruits, beans, seeds, and low-fat dairy products while limiting red meat and sugary drinks.
Reduce or avoid alcohol consumption
One study involving women found that alcohol consumption was associated with decreased blood pressure. Others argue the reverse, claiming that even modest alcohol use can raise blood pressure. Therefore, save your life and limit your alcohol consumption.
Home remedies for lowering high blood pressure and heart rate
To lower blood pressure, the American Heart Association suggests several lifestyle changes, including stress management, giving up tobacco, eating better, and working out regularly as well as executing any medical recommendations.
Weight loss and high blood pressure
According to research, blood pressure can be lowered by dropping as little as 5-10 pounds. Also, medications used to treat high blood pressure will work better if the patient loses weight. To lose or keep a healthy weight, you can exercise regularly and consider taking a weight-loss diet while watching your fat and sugar intake.
Get enough sleep
Even while hypertension can’t be cured by getting more sleep, too little or poor sleep may worsen the condition. Besides, a study found that those who get less sleep are more likely to suffer from hypertension. Therefore, ensure you get adequate sleep per night.
Conclusion
The dangers of high blood pressure are many, including but not limited to stroke, heart attack, low pulse rate, and kidney failure.
A family history of hypertension, not getting enough exercise, eating poorly, not dealing with stress effectively, and smoking raises your risk of developing this illness. You may more likely to develop hypertension if you already have another underlying disease, such as diabetes or pregnancy.
So, to reduce high blood pressure and heart rate, you must get enough sleep, eat a heart-healthy diet, and reduce your alcohol consumption. You must also follow instructions from your doctors concerning high blood pressure medications.
