1. Make an electrocardiogram, especially a dynamic electrocardiogram, for further diagnosis.
2. Do echocardiography to see the movement of ventricular wall.

Large area myocardial infarction is the main cause of sudden death, but your condition does not rule out the possibility of misdiagnosis. Go to the hospital for examination first. After all, the consequences of this disease are too serious.
