A positive ECG flat panel exercise test is highly suspicious for myocardial ischemia and the presence of coronary artery stenosis, which requires formal hospitalization in the cardiology department for coronary angiography and treatment. ECG platelet exercise test is to monitor ischemic changes in ECG after exercise. Positive result, consider coronary artery stenosis, immediately hospitalized, for coronary angiography, can be obvious coronary artery blood vessel stenosis, how much stenosis, stenosis site. If the stenosis of coronary vessels is less than 75%, it is recommended to take oral isosorbide nitrate to expand the crown, aspirin to prevent thrombosis, atorvastatin and other statin drugs orally, and oral diltiazem to prevent and control vasospasm if necessary. If the coronary vessel stenosis is more than 75%, theoretically there is an indication for stent implantation. Patients with myocardial ischemia electrocardiograms consistent with stenosis are the responsible vessel and stent implantation is recommended. Positive ECG plate motion must be regularized to the cardiology department for formal examination and treatment.
