Is my heart palpitation serious?

Question

Accepted Answer

Palpitations are the sensation of your own heartbeat, racing, pounding, skipping, or fluttering, and the honest baseline is that most are benign. The common benign drivers: caffeine, nicotine, alcohol, stress and anxiety, poor sleep, dehydration, fever, decongestants, and hormonal shifts (periods, pregnancy, perimenopause). An occasional skipped-feeling beat (an extrasystole) in an otherwise healthy person is a normal finding, per MedlinePlus. The serious list is about company, not sensation: chest pain, fainting or near-fainting, shortness of breath, unusual sweating, or a racing heart that starts and stops abruptly at rest with no trigger all warrant same-day evaluation, and chest pain plus any of those means 911. Also get checked promptly if palpitations are new and frequent, if you have known heart disease or a family history of sudden cardiac death, or if they come with a genuinely fast sustained rate (over 120 at rest) or with dizziness. The workup is painless: an ECG, sometimes a wearable monitor for a week or two to catch the episodes, blood tests for thyroid and anemia (both common hidden causes), and often caffeine and medication review. What helps immediately: cut caffeine and energy drinks, hydrate, sleep, and treat the anxiety loop, because palpitations and anxiety amplify each other. And a practical trick for a racing episode: vagal maneuvers (bearing down as if straining, or cold water on the face) can stop some racing rhythms, which is worth knowing but is not a substitute for getting a recurring pattern evaluated.
