Biventricular pacing did not increase short-term mortality; supports safety in heart failure with ventricular arrhythmias but leaves longer-term effects open.
Does biventricular pacing affect all-cause mortality in patients with heart failure and ventricular arrhythmias?
In patients with heart failure and ventricular arrhythmias, biventricular pacing over a 3-month period was not associated with excess mortality compared to no pacing.
Lozano et al. (2000) studied this question.
