Palpitationsâ€” sensation that the heart has started to race or pound, or feels like it has skipped a beatâ€”are usually caused by a harmless hiccup in the heartâ€™s rhythm. Sometimes, though, palpitations reflect a problem in the heart or elsewhere in the body.
Palpitations are extremely common. Different people experience them in different ways. You might feel as though your heart is fluttering, throbbing, flip-flopping, or pounding, or that it has missed a beat. Palpitations can appear out of the blue and disappear just as suddenly. Or they might be linked with certain activities, events, or feelings. Some of the most important pieces of information that can help your doctor in pinning them down is how palpitations feel, how often they strike, and when they occur.
Some palpitations result from premature contractions of the heartâ€™s chambers or malfunctions of a heart valve. But a physical exam and electrocardiogram often donâ€™t turn up any problems, which can be frustrating to the patient. If your palpitations arenâ€™t accompanied by dizziness or other symptoms and if you donâ€™t have a valve disorder or other structural problem with your heart, that usually means palpitations are benign.
If you have unexplained palpitations, start with simple steps to help alleviate them.
