Key result
Novel ECG algorithm using V2S/V3R index and r-wave area predicts OTVA origin with ~95% accuracy.
Why the study?
The study aimed to evaluate diagnostic criteria accuracy for determining outflow tract ventricular arrhythmia origin and develop an ECG algorithm to predict its origin.
Does a novel ECG algorithm combining the V2S/V3R index and initial r wave surface area in V1 and V2 accurately predict the origin of outflow tract ventricular arrhythmias?
Observational (n=200)
Yes

May aid noninvasive OTVA localization; hypothesis-generating and requires prospective validation before clinical use.
Zhang et al. (2023) conducted an observational in Outflow tract ventricular arrhythmia (OTVA) (n=200). ECG algorithm combining V2S/V3R index and larger ISA in V1 and V2 was evaluated on Prediction of OTVA origin (Accuracy 95.00%). A novel ECG algorithm combining the V2S/V3R index and larger initial r wave surface area in V1 and V2 predicted the origin of outflow tract ventricular arrhythmia with 95.00% accuracy.
