11. Cardiac Resynchronization Therapy: Different Issues

Show Summary Details

Preview

AV delay (AVD) can be approximated to be either about 45ms or 70ms longer than individual interatrial conduction intervals in biventricular or right ventricular pacing, resp. Biotronik ICS3000 programmer enables filtered esophageal left atrial electrogram (LAE). It can be used irrespective of pacemakers make and model to measure interatrial conduction intervals (IACT) in order to simplify AVD optimization.

Aims

To test the ICS3000 based LAE in biventricular pacing.

Methods

In 13 congestive heart failure (CHF) patients, we compared results of individual echo AVD optimization with 1) factory settings and 2) results of simplified AVD approximation by individual IACT measurement using the ICS3000. AVDs were considered to be optimal if they differed less than 30ms compared to echo results:

Conclusions

1) ICS3000 can be used to simplify AVD optimization in every DDD paced CHF patient. Results are 2) similar to echo AVD optimization in more than half of the patients and 3) considerably superior to factory settings.
