Panic is a subjective feeling, if the patient keeps feeling panic there may be the following cases: 1. Premature beats: the heart beats regularly with a certain rhythm, sometimes there are early beats, that is, early beats are called premature beats. Premature beat patients will feel panic; 2, sinus rhythm in addition to the normal commander issued pulse, issued heart rate, but also in abnormal circumstances such as ectopic rhythm issued pulse appear supraventricular tachycardia, atrial fibrillation, ventricular tachycardia, etc., the patient will feel that the heartbeat is not normal will also feel panic; 3, there are some patients feel panic, but the electrocardiogram does not have any abnormalities, so once there is panic, we should go to the hospital for electrocardiogram diagnosis, the doctor According to the electrocardiogram to determine what the panic is in the end. In case of premature beats, it is recommended to do a 24-hour ECG to see how many premature beats the patient has throughout the day, if there are not many premature beats, no treatment is needed. If some patients have 100-200 or even 1000 premature beats, the situation is fine and no special treatment is needed. If the patient has a combination of coronary artery disease or heart failure, and the premature beats are very wide and malformed, intervention is required. ECG with other abnormal heart rates such as supraventricular tachycardia, ventricular tachycardia, atrial fibrillation, etc. should be intervened according to the patient’s specific situation. If the patient has supraventricular tachycardia that may be paroxysmal, and ventricular tachycardia that may also be paroxysmal, medication or surgery should be performed depending on the situation, and the success rate of surgical treatment for supraventricular tachycardia can now reach 99%. If the ventricular tachycardia is short paroxysmal such as 2-3 and no organic heart disease, it does not need to be treated, but if many patients have heart disease at the same time, it needs to be treated, depending on the situation, with drugs or radiofrequency ablation. In the elderly, the proportion of atrial fibrillation increases with age, and atrial fibrillation is also divided into paroxysmal and persistent, which should be treated according to the patient’s condition, with medication or radiofrequency surgery to achieve a good curative effect. In addition to cardiac causes, there is another category such as hyperthyroidism patients will have a fast heartbeat, such as anemia patients will also have a fast heartbeat. Therefore, for patients with heart panic, the first step is to diagnose with ECG and then the etiology.
