what happens when your heart rate is slow?

Bradycardia is a slower than normal heart rate. The hearts of adults at rest usually beat between 60 and 100 times a minute. If you have bradycardia (brad-e-KAHR-dee-uh), your heart beats fewer than 60 times a minute. Bradycardia can be a serious problem if the heart doesn't pump enough oxygen-rich blood to the body.

Heart disease: Some types of heart disease, such as high blood pressure, are risk factors for AFib, which is a type of arrhythmia. Scarring or abnormal tissue deposits can also cause bradycardia (slow heart rate) or tachycardia (rapid heart rate) by interfering with the heart's electrical system.

When an individual has tachycardia, the upper or lower chambers of the heart beat significantly faster. When the heart beats too rapidly, it pumps less efficiently and blood flow to the rest of the body, including the heart itself, is reduced.

Arrhythmias may cause you to feel premature heartbeats, or you may feel that your heart is racing or beating too slowly. Other signs and symptoms may be related to your heart not pumping effectively due to the fast or slow heartbeat.

Usually, a heart rate will be slower during sleep, faster during daily activities or with exercise, and recover quickly back to a resting rate after exercise.

For most people, a heart rate of 60 to 100 beats a minute while at rest is considered normal. If your heart beats less than 60 times a minute, it is slower than normal. A slow heart rate can be normal and healthy.

If you experience a heart rate that's too high or too low for an extended period of time, it can lead to a variety of potentially serious health complications, including: blood clots. heart failure. recurring fainting spells.

When a slow heart rate is normal A resting heart rate slower than 60 beats a minute is normal for some people, particularly healthy young adults and trained athletes. For them, bradycardia isn't considered a health problem.

Low blood pressure is a measurement of 90/60mmHg or lower. When your blood pressure drops, your heart rate increases and the blood vessels in other parts of the body constrict (narrow) to help maintain blood pressure.

But there are exceptions. Your heart rate may fall below 60 BPM during deep sleep. And physically active adults (and athletes) often have a resting heart rate slower than 60 BPM.

If you have a low diastolic pressure, it means you have a low coronary artery pressure, and that means your heart is going to lack blood and oxygen.

Ventricular tachycardia that is prolonged can result in low cardiac output, low blood pressure, and fainting (syncope).

Your heart rate slows down When our bodies are deprived of oxygen, the heart can't pump fresh, oxygenated blood out to the body. Studies show that about 30 seconds of breath-holding can lead to a lowered heart rate and lower cardiac output.

If your heart rate drops into the 30s, you might not get enough oxygen to your brain, making fainting, lightheadedness, and shortness of breath possible. Blood can also pool in your heart chambers, causing congestive heart failure.

Sometimes our hearts beat slower than 60 beats per minute. This is called bradycardia. For some people, like athletes and healthy, young adults, this heart rate could be normal. But for others, it could be a sign that your brain and other organs aren't getting enough oxygen to function like they should.

But if you have AFib and your heart is beating too slowly, your doctor may recommend a pacemaker along with other treatment. It sends out electrical pulses that take the place of the mixed-up ones, so your heart beats at the right pace. You also might need a pacemaker if you have AFib and congestive heart failure.
