Figure 1 Kaplan-Meier event-free curves for serious arrhythmic events (i.e., sudden cardiac death, cardiac arrest, and resuscitated ventricular fibrillation) based on positive microvolt T-wave alternans (TWA) test (A), nonsustained ventricular tachycardia (NSVT) (B), and ventricular late potentials (LP) (C).
