Key result
Premature His bundle complexes distinguished atrioventricular reentry tachycardia from atrioventricular node reentry tachycardia with 100% sensitivity and specificity.
Why the study?
Current pacing maneuvers to differentiate AVNRT from AVRT lack sensitivity and specificity when AVRT circuits are located away from the pacing site.
Does high-output pacing delivering premature His complexes differentiate AVRT from AVNRT in patients with supraventricular tachycardia?
Observational (n=73)
Does high-output pacing delivering premature His complexes differentiate AVRT from AVNRT in patients with supraventricular tachycardia?
Effect estimate: 100% sensitivity and specificity
Absolute Event Rate: 100% vs 0%
Premature His bundle complexes delivered via high-output pacing at the distal His location can differentiate AVRT from AVNRT with 100% sensitivity and specificity.
No takes yet. Share an insight, caveat, or question.
May facilitate AVRT vs AVNRT differentiation in EP study; hypothesis-generating and requires prospective validation.
Padanilam et al. (2020) conducted an observational in Supraventricular tachycardia (AVRT and AVNRT) (n=73). Premature His bundle complexes (PHCs) was evaluated on Differentiation of AVRT and AVNRT using late PHCs (100% sensitivity and specificity). Premature His bundle complexes distinguished atrioventricular reentry tachycardia from atrioventricular node reentry tachycardia with 100% sensitivity and specificity.
