Two-Chamber Pacing Comes Of Age
A new consensus document on pacemaker device and mode selection for patients where the decision for pacing has already been made reflects the accumulating evidence for the efficacy of dual-chamber pacemakers.
The most important recommendations regarding patients with sinus node dysfunction but intact atrioventricular conduction are that dual-chamber pacing is preferred over single-chamber ventricular pacing (Class I, level of evidence A) and single-chamber atrial pacing (Class I-B), Anne M. Gillis, MD, from the University of Calgary, told MedPage Today.
"Studies indicate that the dual-chamber devices in these patients reduce the incidence of atrial fibrillation and improve some quality-of-life measures," said Gillis, the lead author of the document, which was published online in HeartRhythm.
