What should you know about palpitation hyperthyroidism?

Palpitations may feel like pounding, fluttering, racing, or skipped beats. When hyperthyroidism is active, a person may also notice heat intolerance, excessive sweating, anxiety, difficulty sleeping, diarrhoea, tremor, weight change, or reduced exercise tolerance. These symptoms overlap with other conditions, and palpitations alone do not identify an overactive thyroid. A clinician may check the pulse, blood pressure, neck, and heart, then consider thyroid blood tests and an electrocardiogram based on the history.

Record when the sensation starts, how long it lasts, whether the rhythm feels regular, and what you were doing. Note caffeine, nicotine, medicines, illness, sleep, and other thyroid-related symptoms. Arrange medical review when episodes recur, last longer, or interfere with activity. If you already have hyperthyroidism, take prescribed treatment as directed and do not change it because of one episode. Avoid stimulants until you have discussed the symptoms with a clinician.

Call emergency services for palpitations with chest pain, fainting, severe breathlessness, confusion, or collapse. Seek urgent assessment if a rapid or irregular heartbeat continues at rest, especially with fever, marked weakness, or severe agitation. A brief episode that settles but keeps returning still deserves a routine appointment to identify the rhythm and possible trigger.

Could my symptoms reflect hyperthyroidism or another rhythm problem? Should I have thyroid tests or an electrocardiogram? Which medicines, supplements, or drinks could worsen the sensation? What should I do if an episode lasts longer or feels irregular?
