Discussion

Implication

Heart failure history signals high sudden-death risk among ambulatory NSVT patients; leaves open whether arrhythmia features independently predict outcomes.

Key Points

To evaluate the prognostic significance and characteristics of nonsustained ventricular tachycardia regarding sudden cardiac death in ambulatory patients.
Retrospective review of 37 ambulatory patients with nonsustained ventricular tachycardia (≥3 consecutive beats) identified from 518 consecutive patients undergoing 24-hour Holter monitoring.
Tracked clinical outcomes over a mean follow-up of 19 ± 5 months and analyzed electrocardiographic tachycardia characteristics (rate, episodes/day, beats/episode, prematurity index, and concurrent arrhythmias).
Sudden cardiac death occurred in 10 of 37 patients (27%) during the follow-up period.
Sudden death was significantly concentrated among patients with congestive cardiomyopathy or heart failure (9 of 19 [47.4%]) compared to those without heart failure (1 of 18 [5.6%]).
No specific ventricular tachycardia characteristics, including rate, episode frequency, duration, or prematurity index, were predictive of sudden death.

Structured PICO

Does nonsustained ventricular tachycardia predict sudden cardiac death in ambulatory patients?

Population

37 patients with nonsustained ventricular tachycardia (greater than or equal to triplets) identified retrospectively from a population of 518 consecutive patients referred for 24-hour Holter monitoring.

Outcome

Sudden cardiac deathhard clinical

In ambulatory patients with nonsustained ventricular tachycardia, underlying congestive cardiomyopathy or heart failure is a strong predictor of sudden cardiac death, whereas specific characteristics of the ventricular tachycardia are not.
