Is increased heart rate a symptom of palpitations?

Rapid heartbeat is usually a common manifestation of palpitations. Palpitations, which refer to an uncomfortable sensation or awareness of heartbeats, can be caused by various factors such as emotional fluctuations, physical activity, medication side effects, or heart diseases. When the heart beats faster, individuals may feel strong, rapid, or irregular heartbeats—this sensation is known as palpitations. Although increased heart rate itself is not necessarily a sign of a serious condition, medical attention should be sought promptly if palpitations occur frequently or are accompanied by other symptoms such as chest pain, shortness of breath, or dizziness, in order to rule out potential cardiac problems. As one form of palpitation, rapid heartbeat warrants sufficient attention and appropriate measures should be taken based on the specific circumstances.
