Electrocardiographic measures of ventricular repolarization dispersion and arrhythmic outcomes among ST elevation myocardial infarction patients with pre‐infarction angina undergoing primary percutaneous coronary intervention

摘要

Arrhythmias are considered one of the major causes of death in ST elevation myocardial infarction (STEMI), particularly in the early in‐hospital phase. Pre‐infarction angina (PIA) has been suggested to have a protective role.
