10 things you need to know about VIP® (Abbott™)

  1. the VIP® algorithm programmable in Abbott™ devices corresponds to an AV delay hysteresis
  2. the AV delay is prolonged over a limited number of intervals to promote the return of intrinsic conduction
  3. at the end of the prolonged AV period, if no ventricular event has occurred, ventricular pacing is delivered
  4. there can be no blocked P wave during this search, given that ventricular pacing always occurs at the end of the prolonged AV delay in the absence of ventricular sensing
  5. the main advantage of this algorithm is therefore to permanently maintain a 1:1 activation ratio between atria and ventricles
  6. there is an increased risk of pacemaker mediated tachycardia
  7. 3 parameters are programmable
  8. the VIP® Extension corresponds to the extension of the AV delay applied to the programmed AV delay; the total value of the AV delay cannot exceed 450 ms
  9. the search interval corresponds to the time interval between each intrinsic conduction search (programmable from 30 seconds to 30 minutes)
  10. the number of consecutive cycles the device extends the AV delay to search for the occurrence of intrinsic conduction (programmable to 1, 2 or 3 cycles)
