Treatment of brief episodes of highly symptomatic supraventricular and ventricular arrhythmias: a methodological review.

: Treating brief episodes of tachycardias remains a challenge and can cause significant frustration for electrophysiologists. Although, the broadening of the indication is clearly visible, currently available sequential mapping techniques often fail to map short-lived arrhythmias. New beneficent technological features permit the mapping of these previously considered unmappable arrhythmias, and offer a new perspective in their management.
