Key result
Return cycle mapping after entrainment localized the central common pathway of ventricular tachycardia without pacing at the pathway, with an estimated sufficient interelectrode distance of 8.5 mm.
Why the study?
Does return cycle mapping after entrainment localize the central common pathway of ventricular tachycardia without pacing at or recording potentials from the pathway?
Does return cycle mapping after entrainment localize the central common pathway of ventricular tachycardia without pacing at or recording potentials from the pathway?
Return cycle mapping after entrainment can localize the central common pathway in reentrant ventricular tachycardia without needing to pace at or record potentials from the pathway, potentially improving ablation success.

Hypothesis-generating for VT pathway localization in animal models; leaves open translation to human ablation outcomes.
Nitta et al. (1998) studied Ventricular Tachycardia. Return cycle mapping after entrainment was evaluated on Localization of the central common pathway and required electrode resolution. Return cycle mapping after entrainment localized the central common pathway of ventricular tachycardia without pacing at the pathway, with an estimated sufficient interelectrode distance of 8.5 mm.
