Abstract:

Objective To evaluate the effectiveness and safety of minimizing ventricular pacing mode. Methods The Medtronic Adapta ADD01 pacemakers were implanted in 32 patients with sick sinus syndrome. The percentages of ventricular pacing and incidences of arrhythmia were compared two months after application of managed ventricular pacing (MVP) mode, fixed long extension of atrioventricular delay (LAVD) mode and enhanced automatic atrioventricular interval search (Search AV+) mode. Results Patients were followed up for 6 months, and no pacemaker-associated atrial and ventricular arrhythmias and other adverse events were observed. In MVP mode, the percentage of ventricular pacing (0.35%) was significantly lower than those in LAVD mode (0.65%) and Search AV+ mode (0.7%)(P<0.05). Compared with LAVD mode, Search AV+ mode mildly increased the percentage of ventricular pacing (P>0.05). Conclusion MVP mode is better than Search AV+ mode and LAVD mode in minimizing ventricular pacing.
