Mapping the critical diastolic pathway in intra-atrial reentrant tachycardia using an automated voltage mapping program.
This case report demonstrates the use of an automated voltage mapping algorithm to facilitate the rapid mapping of the low-voltage zone and isolate the critical diastolic pathway of an intra-atrial reentrant tachycardia circuit. Catheter ablation targeted to this pathway successfully terminated the arrhythmia.
