Figure 1 Plot of infarct size characteristics versus left ventricular ejection fraction. The regression lines are based on data from all 48 subjects. However, individual data points are shown only for patients with inducible monomorphic ventricular tachycardia (circles) and those without inducible ventricular arrhythmias (squares).
