Sinus bradycardia st elevation needs to be considered in terms of the severity of the disease based on the presence of coronary artery disease, myocarditis, and other etiologies. Sinus bradycardia is a sinus rhythm of less than 60 beats per minute. In general, the heart rate is greater than 50 times / min but less than 60 times / min, the patient’s mental state is good, clear-headed, in addition to the vital signs such as respiratory rate, cardiac rhythm, blood pressure and so on is basically normal, at this time the sinus bradycardia will not have too big problem. Sinus bradycardia with st-segment elevation, especially st-segment elevation upward, may have occurred myocardial infarction, but the severity of its infarction according to the infarction site and st-segment elevation of the time to judge. In the case of non-specific st-segment elevation, no special treatment is necessary, but regular follow-up is required. If the patient has frequent episodes of chest pain, the cause of the chest pain should be further clarified. Sinus bradycardia st elevation can be considered to be caused by coronary heart disease, myocarditis and other diseases, according to the clinical symptoms of angina pectoris, dyspnea, etc., myocardial enzyme profiling whether there is myocardial infarction, myoglobin elevation, etc., and can be further clarified through the echocardiography and coronary artery angiography if necessary. Sinus bradycardia with elevated ST may or may not be serious, and should be evaluated according to all aspects of the patient’s condition. If the ECG shows elevated sinus bradycardia ST, consult a physician for prompt management.
