Single-pass DDD lead may enable sequential pacing in AV block; leaves open threshold optimization and safety in larger studies.
Does a single-pass DDD lead provide stable atrioventricular sequential pacing in patients with symptomatic higher degree AV block?
A single-pass DDD lead is feasible for short- and long-term pacing, but requires further improvement due to relatively high atrial stimulation thresholds and potential for phrenic nerve stimulation.
Naegeli et al. (1999) studied Symptomatic higher degree AV block and intact sinus node function (n=8). Single-pass, tined DDD lead in combination with a DDDR pacemaker was evaluated on Feasibility and short- and long-term stability of atrioventricular sequential pacing (atrial pacing thresholds). A new single-pass DDD lead demonstrated feasibility for short- and long-term pacing in 8 patients, though atrial pacing thresholds remained relatively high (averaging 3.4 V at 6 months).
