Supports VDD stability in AV block; leaves open need for RCTs versus dual-chamber systems.
Does single-lead VDD pacing provide reliable atrial sensing and ventricular pacing in patients with AV block and normal SA node function?
Single-lead VDD pacing is a reliable and stable method for maintaining AV synchrony over 2 years in both adults and children with AV block and normal SA node function.
Ovsyshcher et al. (1996) studied this question.
