Exercise Q, R, and S wave amplitude changes, called the QRS score, have been reported to be a marker of exercise-induced myocardial ischemia. Therefore, in this study, using the exercise QRS score, we sought to determine if slow coronary flow (SCF) phenomenon is associated with the exercise-induced myocardial ischemia.
