what does it mean when your heart beats really fast for no reason?

Heart palpitations may be a sign or symptom of arrhythmia, an irregular heartbeat, or other heart conditions such as heart attack, heart failure, heart valve disease, or cardiomyopathy. Although palpitations are very common and usually harmless, they can be frightening when they happen and may cause anxiety.

Tachycardia refers to a fast resting heart rate, usually over 100 beats per minute. Tachycardia can be dangerous, depending on its underlying cause and on how hard the heart has to work. Some people with tachycardia may have no symptoms or complications.

Tachycardia is a heart condition where one's heart is beating too fast, more than 100 beats per minute when at rest. In general, normal resting heart rate is between 60 and 100 beats per minute while with tachycardia, the heart's chambers are working too hard and beating faster than is considered healthy.

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.

Tachycardia is a fast or irregular heart rhythm, usually more than 100 beats per minute and as many as 400 beats per minute. At these elevated rates, the heart is not able to efficiently pump oxygen-rich blood to your body.

They often happen when you have over exerted yourself, for example through vigorous exercise, or when you are feeling particularly anxious or stressed. Ectopic beats are early (premature) or extra heartbeats, which can cause you to have palpitations. 'Ectopic' means out of place.

Lightheadedness. If you have an arrhythmia that causes your heart to beat too fast or too slow, you may feel lightheaded or dizzy. This happens because your heart cannot pump blood effectively during excessively fast or slow heart rates.

Your heart might beat faster, slower or differently than usual for a few reasons. Rapid, fast heartbeat at rest could be caused by stress, caffeine, alcohol, tobacco, thyroid pills, cold medication, asthma drugs or diet pills.

The disruption of the normal electrical impulses that regulate the heart rate and pumping rhythm get out of sync and the cause the heart to beat faster. There might be several underlying causes why this might happen including reaction to certain medication, birth defects, alcohol use, hypertension and many others.

Wolff-Parkinson-White (WPW) syndrome is a relatively common heart condition that causes the heart to beat abnormally fast for periods of time. The cause is an extra electrical connection in the heart. This problem with the heart is present at birth (congenital), although symptoms may not develop until later in life.

Although it often feels like a skipped heartbeat, a premature heartbeat is actually an extra beat. Even though you may feel an occasional premature beat, it seldom means you have a more serious problem. Still, a premature beat can trigger a longer lasting arrhythmia — especially in people with heart disease.

Hard exercise, anxiety, certain drugs, or a fever can spark it. When it happens for no clear reason, it's called inappropriate sinus tachycardia (IST). Your heart rate might shoot up with just a little movement or stress. Or it might be high when you're doing nothing.

This feels like a skipped beat and is often followed by a noticeably forceful contraction as the lower chambers (ventricles) clear out the extra blood they accumulated during the pause. These premature beats are almost always benign, meaning they aren't life-threatening or the sign of a heart attack in the making.

It can feel like your heart is actually fluttering or skipping a beat or two, or beating too hard or too quickly. You may notice these feelings in your chest or at pulse points in your throat or neck. Heart flutters or palpitations can be a sign of too many thyroid hormones flooding your system (hyperthyroidism).

There are many heart rhythm disorders (arrhythmias) that can cause tachycardia. Sometimes, it's normal for you to have a fast heartbeat. For instance, it's normal for your heart rate to rise during exercise or as a response to stress, trauma or illness.

Overview. Heart palpitations (pal-pih-TAY-shuns) are feelings of having a fast-beating, fluttering or pounding heart. Stress, exercise, medication or, rarely, a medical condition can trigger them. Although heart palpitations can be worrisome, they're usually harmless.
925381
Tachycardia. Tachycardia means that your heart is beating much faster than normal, usually more than 100 beats per minute. Some forms of tachycardia are not serious and easily treated while others can be life-threatening.
