Heart rate turbulence predicts all-cause mortality and sudden death in congestive heart failure patients.
Abnormal heart rate turbulence (HRT) has been documented as a strong predictor of total mortality and sudden death in postinfarction patients, but data in patients with congestive heart failure (CHF) are limited. ⋯ HRT is a potent risk predictor for both heart failure and arrhythmic death in patients with class II and III CHF.
