A person’s pulse rate, which indicates their heart rate, is how many times the heart beats per minute. Doctors usually consider a low pulse as less than 60 beats per minute. They call this bradycardia.
Most doctors consider high blood pressure as greater than 130/80, according to the new guidelines released by the American Heart Association.
Severely high blood pressure is pressure greater than 170/100.
In this article, we take a look at the possible causes of high blood pressure with a low pulse.
Some medical conditions or medications can cause high blood pressure and a low pulse.
Examples of beta-blockers include:
- atenolol (Tenormin)
- metoprolol (Lopressor, Toprol XL)
- nebivolol (Bystolic)
- propranolol (Inderal)
These medicines work to block beta receptors in the heart. Stimulating these receptors increases heart rate while blocking them decreases heart rate.
A lower heart rate is beneficial for a person who has heart problems because it allows more time for the heart to fill. When the heart beats slower, it also requires less oxygen. This places less strain on the heart and “rests” the heart.
Doctors will sometimes prescribe beta-blockers to people who have high blood pressure, congestive heart failure, or a cardiac arrhythmia when the heart beats irregularly. For this reason, a person who already has high blood pressure can have a lower heart rate with beta-blockers.
Doctors can also prescribe other medications to reduce blood pressure, including:
- calcium channel blockers
- angiotensin receptor blockers
- angiotensin converting enzyme inhibitors
These drugs do not usually affect the heart rate while treating blood pressure.
The Cushing reflex is a rare occurrence that causes a low pulse and high blood pressure.
The reflex is the result of the body’s response to increased intracranial pressure. Intracranial pressure is the pressure inside the head and is a measurement of blood pressure in the brain.
The brain rests inside a person’s skull, so, if it swells, there is only so far it can expand. As a result, swelling causes intracranial pressure to increase.
The Cushing reflex is one of the body’s ways to try and keep pressure from getting too high in the skull. It signals receptors in the heart to slow the heart rate down to lower the intracranial pressure.
Severe medical conditions usually activate the Cushing reflex. These conditions include:
The Cushing reflex is an emergency. Once doctors recognize this condition, their goal is to try and treat the cause and reduce the intracranial pressure in the brain. If the pressure gets too high, it can permanently damage the brain. A person can die from excessively high intracranial pressure.
Problems with heart conduction
A low pulse rate can sometimes be an indicator of a problem with the heart’s electrical conduction pathway.
The heart has an electrical system that travels in a distinct pattern to make the heart beat with a regular rhythm. If there is damage, scarring, or overstretching of the heart, the electrical system may not work as effectively. This can cause a low pulse rate.
Chronic high blood pressure can contribute to damage to the electrical system that, in turn, leads to a low pulse rate. Other causes of damage include smoking, a history of heavy drug or alcohol use, or aging of the heart.
A person whose pulse suddenly seems to be slowing down for no known reason should see a doctor. This is especially true if they feel dizzy or short of breath.
On certain occasions, a person may require a pacemaker or other intervention, such as cardiac ablation, to repair the damaged electrical heart pathways.
When to see a doctor
If a person experiences chest pains along with a low pulse and high blood pressure, they should speak to their doctor.
A person should seek immediate medical attention if they have the following symptoms along with a low pulse and high blood pressure:
- dizziness or lightheadedness
- feeling faint or fainting
- shortness of breath
- chest pains
These symptoms may indicate that a person requires a hospital stay and possibly a pacemaker to treat whatever is causing their underlying heart problem.
High blood pressure and a low pulse rate is a fairly rare occurrence. People are more likely to have high blood pressure alone unless they take medications that may affect their pulse rate.
Certain medicines in individuals with high blood pressure can result in a low pulse rate and high blood pressure. Rarely, an increase in intracranial pressure can induce the Cushing reflex and a low pulse rate and high blood pressure.
How can I stabilize my blood pressure?
A wide range of factors influences blood pressure, including anxiety, stress, and medications. High blood pressure can have severe complications, such as a heart attack or stroke. A person can address fluctuating blood pressure with home remedies and lifestyle changes. Learn more about normalizing blood pressure here.
How can you tell when you have high blood pressure?
High blood pressure causes no symptoms until it becomes severe. In this article, we discuss the myths and truths of high blood pressure symptoms. We also look at how to tell when blood pressure is too high and how to interpret blood pressure readings.
Fifteen good foods for high blood pressure
The diet has a strong influence on blood pressure. Certain foods are scientifically shown to reduce high blood pressure, including berries, bananas, and oats. In some cases, dietary changes alone can lower blood pressure to normal levels. Learn more about good foods for high blood pressure, or hypertension, here.
