- SafeR pacing mode has been designed to promote native atrioventricular conduction by minimizing unnecessary right ventricular pacing in Sorin devices
- the device provides AAI pacing while continuously monitoring AV conduction
- there is one switch criterion from AAI to DDD for each AV block degree
- the device switches to DDD when PR or AR intervals are longer than the programmed maximum programmable value during 6 consecutive cycles (AVBI)
- the AVB I (first degree AV block) criterion can be programmed to rest + exercise or to exercise only
- the device switches to DDD if it senses 3 non consecutive blocked sensed or paced atrial events in the last 12 ventricular cycles (AVBII)
- the device switches to DDD if it senses two consecutive blocked sensed or paced atrial events (AVBIII)
- the device switches to DDD if a ventricular pause is longer than the programmed value (programmable: 2, 3, 4 seconds)
- the device switches automatically from DDD to AAI mode after 100 paced ventricular cycles
- the device also switches automatically from DDD to AAI when it senses 12 consecutive spontaneous ventricular events
