Palpitations can be seen in increased heart beat, arrhythmia, cardiac neurosis and other conditions. 1. Enhanced heartbeat: Physiological reasons can be caused by drinking alcohol, coffee, strong tea or certain medicines, as well as high blood pressure and other causes of ventricular hypertrophy, hyperthyroidism, anemia and hypoglycemia, which can lead to increased heart contraction and increased heart rate, which can be manifested as palpitations and panic. 2. Arrhythmia: Tachycardia, bradycardia, pre-systole, atrial flutter or fibrillation and other arrhythmias can lead to palpitation clinical manifestations. 3. Cardiac neurosis: mainly seen in women, caused by autonomic dysfunction, palpitations may appear in anxiety, emotional excitement and so on. When palpitation is not relieved after rest or lasts for a long time, it should be diagnosed and treated in time to avoid delaying the condition.
