Should not yet change practice; leaves open benefit of overdrive pacing for atrial ectopy in larger trials.
Does a new pacing algorithm for overdrive suppression reduce atrial arrhythmias in patients with dual chamber pacemakers?
A novel pacing algorithm for overdrive suppression safely reduces atrial ectopic activity and salvos in patients with dual chamber pacemakers.
Murgatroyd et al. (1994) studied this question.
