Myocardial ischemia can cause panic, but panic is not the only symptom of cardiac ischemia, but also arrhythmia and cardiac neurosis. Panic is mainly caused by changes in the frequency and rhythm of the heartbeat, and can also occur in the presence of normal heart activity. Panic not only occurs in the pathological state, but also in normal people when they are in strenuous activity or emotional excitement. When myocardial ischemia increases the oxygen demand of the heart, the sympathetic nerve is excited and the heart rate is accelerated to provide the oxygen demand of the heart, and the symptoms of panic will appear when the heart rate is too fast. In addition to heart disease, other system diseases such as lung disease and anemia can also cause compensatory acceleration of the heart rate, resulting in symptoms of panic. After the symptoms of panic are excluded from physiological factors such as strenuous exercise, emotional excitement, etc., you should go to a regular hospital in time, measure blood pressure under the guidance of a physician, improve relevant examinations such as electrocardiogram, cardiac ultrasound, etc. to find the cause of the disease, and treat the cause and symptoms in a timely manner.
