Why the study?
Do QT parameters correlate with infarct size or predict arrhythmia inducibility in patients with coronary artery disease and life-threatening ventricular arrhythmias?

QT dispersion should not yet guide arrhythmia risk assessment in CAD; leaves open scar burden by perfusion imaging as a predictor.
Do QT parameters correlate with infarct size or predict arrhythmia inducibility in patients with coronary artery disease and life-threatening ventricular arrhythmias?
QT dispersion does not correlate with infarct size or predict the inducibility of ventricular arrhythmias in patients with coronary artery disease, whereas scar tissue burden by perfusion imaging does.
