    T wave alternans (TWA) of increasing subtlety. A. Gross alternans of elevated ST/T-segments in a patient with angina pectoris preceding ventricular tachycardia (VT). B. Visible alternans of T wave polarity in a woman without angina, heralding polymorphic VT. C. Subtle but visible TWA after tachycardia termination, without arterial pressure alternans (bottom). D. Visually inapparent microvolt-level TWA, uncovered by digital signal processing. *=The more positive T wave of each alternating pair.

    The utility of the T-peak to T-end (Tpe) interval for the prediction of ventricular tachyarrhythmia and death. A. Kaplan-Meier plots of freedom from appropriate implantable cardioverter-defibrillator therapy, stratified by tertiles (T1, T2, T3) of corrected Tpe (Tpec). B. Kaplan-Meier plots of all-cause mortality, stratified by tertiles of Tpec. C. Kaplan-Meier plots of arrhythmia-free survival, stratified by tertiles of Tpec.
