Tracing
N° 5
Manufacturer Microport CRM Device PM Field SafeR mode
Patient
  • 62-year-old woman
  • Reply DR pacemaker (Microport CRM-Sorin) for sinus dysfunction and paroxysmal AV block
  • SafeR algorithm
  • Episodes of switch to DDD for pause
Graph and trace
  • Atrial pacing with spontaneous ventricular activation
  • Dropped atrial pacing
  • Ventricular pause of 2 seconds (2 seconds setting)
  • Switch to DDD (vertical line)
  • Atrial and ventricular pacing
Comments
  • This tracing shows an example of switch for ventricular pause
  • The device switches to DDD if a ventricular pause is longer than the programmed value
  • This parameter can be programmed to 2, 3 or 4 seconds
