Under normal circumstances, a heart rate of 60-100 beats per minute is normal, so a heartbeat of 73 beats per minute is normal. If the patient still has conscious panic in this case, cardiac neurosis due to phytodysfunction is usually considered, in which case the objective indicators are normal. If the electrocardiogram, cardiac function tests, electrocardiogram and coronary angiogram are all within the normal range, but the patient still suffers from spontaneous panic attacks, the autonomic function should be regulated. Other endocrine metabolic diseases should also be checked to see if the patient has thyroid dysfunction or adrenal cortical dysfunction, if these conditions occur, the patient may also have clinical symptoms of spontaneous panic.
