Patients sometimes experience panic and chest tightness, and there are two main possibilities to consider in this case: first, angina symptoms caused by myocardial ischemia, and second, panic and shortness of breath manifested by cardiac arrhythmia. In the case of angina pectoris, the patient is often based on severe stenosis of one or more of the three coronary arteries of the heart, and when the stenosis reaches a certain level, there can be myocardial cell ischemia and hypoxia, causing chest tightness and chest pain due to lactic acidosis. For such patients, oral antiplatelet drugs, lipid regulating and stabilizing drugs, coronary dilation drugs, and if necessary, imaging surgery or even stenting to open the narrowed vessels should be performed. For arrhythmias that cause panic and chest tightness, patients should go to the hospital for an electrocardiogram to determine what kind of arrhythmia it is, especially the electrocardiogram during the onset of chest tightness is most important. If it is determined what kind of arrhythmia the patient has, the appropriate treatment should be taken. Generally speaking, a slower heartbeat is treated with pacemakers; a faster heartbeat is treated with radiofrequency ablation surgery. These procedures are minimally invasive and do not require general anesthesia or open-heart surgery, and the recovery rate is generally high.
