Figure 4 Kaplan-Meier Survival Curves for Arrhythmia-Free Survival
Stratified according to both electrophysiology study (EPS) and T-wave alternans (TWA) results. EPS (–) = EPS negative for inducible sustained ventricular tachycardia (VT); EPS (+) = EPS positive for inducible sustained VT; TWA (–) = TWA negative; TWA (+/I) = TWA positive or indeterminate (non-negative).
