You shouldn't take beta-blockers if you have low blood pressure or a slow pulse, because bringing down your heart rate more can cause dizziness and lightheadedness.

Heart problems: Among the heart conditions that can lead to low blood pressure are an abnormally low heart rate (bradycardia), problems with heart valves, heart attack and heart failure.

Heart rate is a good measure of how far a person is pushing themselves during exercise. A low heart rate during exercise may mean that a person could increase the intensity of that activity, while a heart rate that is too high can be dangerous.

When your heart is beating too fast, it may not pump enough blood to the rest of your body. This can starve your organs and tissues of oxygen and can cause the following tachycardia-related signs and symptoms: Shortness of breath. Lightheadedness.

When your heart beats too fast, it can't pump out enough blood. You might feel tired, short of breath, or dizzy as a result of this condition that starts in the upper chambers of your heart.

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. For some people, however, bradycardia doesn't cause symptoms or complications.

You should visit your doctor if your heart rate is consistently above 100 beats per minute or below 60 beats per minute (and you're not an athlete). In addition to a heart rate, you should look out for other symptoms such as: being short of breath. fainting.

In response to a loss in pumping capacity, the heart begins to beat faster. The patient experiences this as a racing or throbbing heartbeat. When the heart stops working effectively, it can change sodium levels in the blood. This leads to memory loss, confusion, and a general feeling of disorientation.

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.

Having bradycardia (say "bray-dee-KAR-dee-uh") means that your heart beats very slowly. 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.

It's a sign of good health. But if it's too slow, it could be a symptom of a condition called bradycardia. Normally, your heart beats 60 to 100 times a minute when you're at rest. But with bradycardia, it goes down to less than 60 beats a minute.

If the heart beats too fast, contractions are shallow and not enough blood is pumped with each heartbeat. As a result, the fetus can go into heart failure. The most common form of this condition is called supraventricular tachycardia (SVT), in which the heart rate can be faster than 200 beats per minute.
527673
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.
665927
Your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. This “recovery heart rate” is measured as part of an exercise stress test.

In other people, bradycardia is a sign of a problem with the heart's electrical system. It means that the heart's natural pacemaker isn't working right or that the electrical pathways of the heart are disrupted. Sometimes, the heart beats so slowly that it doesn't pump enough blood to meet the body's needs.

In fact, when your heart doesn't beat normally, its electrical system is likely out of step. When your heart beats too fast, too slow, or skips irregularly, it is called arrhythmia. Your heart can't pump blood through your body well, and that can cause damage to your lungs, brain, and other organs.
