Is frequent palpitation a sign of myocardial ischemia?

Frequent palpitations are not necessarily indicative of myocardial ischemia. Although myocardial ischemia may cause palpitations during an episode, the causes of palpitations are diverse, including both physiological and pathological factors. Physiological causes include mental stress, vigorous exercise, smoking, and consumption of strong tea or coffee. Pathological causes are more complex and may include left ventricular hypertrophy due to hypertension, heart failure, arrhythmia, anemia, hyperthyroidism, and autonomic dysfunction. Therefore, patients experiencing frequent palpitations are advised to seek timely medical attention and undergo tests such as electrocardiography (ECG) to determine the specific cause of the palpitations, thereby enabling appropriate treatment.
