What does this research mean for the field?

Idiopathic ventricular tachycardia exhibits two distinct body surface potential map patterns: a stable pattern corresponding to an infundibular origin for left bundle branch block (LBBB) morphologies, and an evolving pattern corresponding to an apical origin for right bundle branch block (RBBB) morphologies. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Implication

BSPM patterns may distinguish infundibular from apical idiopathic VT origins; hypothesis-generating and should not yet change ablation practice.

Structured PICO

Does body surface potential mapping identify the origin of idiopathic ventricular tachycardia in patients with symptomatic idiopathic VT?

Population

12 consecutive patients (3 women and 9 men; mean age, 42±13 years) presenting symptomatic idiopathic ventricular tachycardia (VT) referred for electrophysiological study, with normal basal ECG, chest radiograph, and echocardiogram.

Intervention

Body surface potential mapping (BSPM) during ventricular tachycardia

Outcome

Differences in body surface potential map patterns between different idiopathic VT morphologies (LBBB vs RBBB)surrogate

Body surface potential mapping can differentiate between right ventricular outflow tract (LBBB pattern) and left ventricular apical (RBBB pattern) origins of idiopathic ventricular tachycardia.
