Relevance of electrograms and transient entrainment for antitachycardia devices

Clearly, understanding what occurs during rapid pacing of tachyarrhythmias due to reentry with an excitable gap does not provide the panacea to the rapid pacing treatment of these arrhythmias. However, it does advance the field considerably, and provides insights which should be useful for the development of improved antitachycardia pacing techniques.
