What causes a rapid heartbeat?
Recently, I have been feeling that my heart beats faster than usual. I would like to know what causes this condition—whether it is due to illness or lifestyle habits—and whether I should visit a hospital for an examination?

Tachycardia, or an abnormally rapid heart rate, may be related to physiological and pathological factors.
Tachycardia refers to a heart rate that exceeds the normal range, typically defined as more than 60-100 beats per minute in adults. It can be caused by various factors, including both physiological and pathological reasons. Physiological tachycardia commonly occurs after strenuous exercise, emotional excitement, or consumption of caffeine or nicotine. In these situations, the body requires more oxygen and nutrients, and the heart increases its rate to meet these demands.
Pathological causes include arrhythmias such as atrial fibrillation and tachycardia itself, which directly affect the heart's rhythm. Hyperthyroidism, caused by excessive secretion of thyroid hormones, can increase both metabolic rate and heart rate. Additionally, systemic conditions such as anemia and electrolyte imbalances may also lead to a rapid heartbeat.
If the tachycardia is physiological, it may be improved by lifestyle modifications and avoiding stimulant substances. However, if it is pathological, timely medical consultation is recommended for professional diagnosis and treatment.
