Low variability of cycle lengths in nonsustained ventricular tachycardia as an independent predictor of mortality after myocardial infarction.
In a group of 191 postinfarction patients, the low variability of cycle lengths in nonsustained ventricular tachycardia was associated with poor prognosis during follow-up. By use of Cox model analysis it was found that reduced ventricular rate variability was a powerful independent predictor of sudden death and all-cause mortality in this group of patients.
