Does the presence of NSVT act as an independent marker for increased overall mortality and sudden death in patients with severe heart failure?
In patients with severe heart failure, the presence of NSVT on a 24-hour Holter monitor is a significant independent marker for increased mortality and sudden death risk.
In patients with CHF, NSVT is an independent marker for increased overall mortality rate and sudden death. The absence of NSVT and ventricular repetitive beats in a 24-hour Holter indicates a low probability of sudden death.
Doval et al. (1996) studied this question.
