They can also feel like the heart skips a beat. Some people feel palpitations as a pounding in the chest or neck; others feel them as a general sense of unease.

Why Does My Heart Feel Like It Skipped a Beat?
Palpitations can be triggered by:. People with certain medical conditions, such as heart disease, anemia, and an overactive thyroid gland hyperthyroidism are more likely to experience palpitations. Palpitations can be related to drugs and medications such as cocaine, amphetamines, diet pills, some cough and cold remedies, some antibiotics, thyroid hormone, digoxin, or asthma remedies. Some palpitations stem from premature contractions of the heart's upper chambers atria.

When the atria contract a fraction of a second earlier than they should, they rest an instant longer afterward to get back to their usual rhythm. 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.

Two other heart rhythm disturbances that can cause palpitations from above are atrial fibrillation and supraventricular tachycardia. Atrial fibrillation is an irregular and often rapid heartbeat caused by chaotic electrical activity in the heart's upper chambers. Supraventricular tachycardia is a faster-than-normal heart rate tachycardia means fast heart rate that begins above the heart's lower chambers. Both of these may cause palpitations that may be brief or prolonged. Both should be evaluated by your physician. Early contractions of the ventricles can also cause palpitations.
A solo premature ventricular contraction, or even a couple in a row, isn't usually a problem unless it's accompanied by fainting, shortness of breath, or other symptoms. A long run of premature ventricular contractions one after the other, though, is worrisome. They can degenerate into the deadly cardiac chaos known as ventricular fibrillation. Problems with the heart's timekeeper, called the pacemaker or sinus node, can cause palpitations. So can a breakdown in the coordination between the upper and lower chambers. Scar tissue in the heart from a heart attack or other injury and valve problems such as mitral valve prolapse can also lead to palpitations.
Palpitations tend to come and go. Unfortunately, they are usually gone by the time you get to the doctor's office. That makes pinning them down a joint effort.
