Peroperative epicardial and transmural mapping followed by cryoablation revealed that reflected reentry in a small area of working myocardial cells was the likely cause of incessant ventricular bigeminy.
Case Report (n=1)
Incessant monomorphic ventricular bigeminy was studied in a young patient with no organic heart disease. The arrhythmia could not be controlled by drug therapy. Spontaneous and artificial variation of the heart rate showed that reentry was the most likely arrhythmogenic mechanism. Peroperative epicardial and transmural mapping revealed an epicardial focal origin which was cryoablated. Reflected reentry occurring in a small area of working myocardial cells appeared to be the most likely explanation for this arrhythmia.
Hemel et al. (Fri,) conducted a case report in Incessant monomorphic ventricular bigeminy (n=1). Cryoablation was evaluated on Arrhythmia mechanism and origin. Peroperative epicardial and transmural mapping followed by cryoablation revealed that reflected reentry in a small area of working myocardial cells was the likely cause of incessant ventricular bigeminy.
