Brief Summary:
Observational study on long PR interval using the SafeR mode in bradycardia patients.

Condition or disease Intervention/treatment
Sinus Node Dysfunction Atrioventricular Block Device: dual chamber pacemaker with SafeR algorithm

Detailed Description:
This observational trial aims to study the evolution of the PR interval in patients implanted with a dual chamber pacemaker with the SafeR mode. The investigators will assess the prevalence and the incidence of PR lengthening and the investigators will study the long PR interval management by physicians, depending on the data embedded in the pacemaker.

Intervention Details:
  • Device: dual chamber pacemaker with SafeR algorithm
    SafeR is an AVB management algorithm: it provides AAI pacing while continuously monitoring AV conduction, it switches to DDD when detecting AVB I, II or III, according to the following criteria: (1) AVB I: 6 long PR intervals, (2) AVB II: 3 blocked atrial events/12 cycles, (3) AVB III: 2 consecutive blocked atrial events. It switches back to AAI mode when needed.
    Other Name: Reply DR (Sorin Devices)

Primary Outcome Measures :
  1. Prolonged PR interval (> 200ms) in patients without AVB I at baseline (Incidence of "clinical" AVB1) [ Time Frame: at 12 months ]
    This incidence will be measured using PR/AR histograms stored in the device memory
