Vp suppression algorithm and decrease in unnecessary right ventricular pacing

Tracing

N° 1

Manufacturer Biotronik Device PM Field Pacing Modes

Patient

• 71-year-old man
• Dual-chamber pacemaker (Biotronik^TM) for symptomatic sinus dysfunction with prolonged PR interval
• Programming in DDD mode at 60 bpm; 6 months after implantation, 100% ventricular pacing and 85% atrial pacing
• Programming of the Vp-suppression algorithm

Graph and trace

• DDD mode: atrial pacing and ventricular pacing
• Programming of the Vp suppression algorithm (vertical black line): atrial pacing and spontaneous ventricular event (long PR pattern)

Comments

• This tracing highlights the interest of the Vp-suppression algorithm (Biotronik) to reduce the pourcentage of unnecessary right ventricular pacing
• The AAI-DDD (Vp-suppression) mode has been designed to allow pacing in ADI mode with permanent monitoring of atrioventricular conduction and switching to DDD mode when the device detects an alteration in atrioventricular conduction
