Key result
Recording the activation sequence of the His bundle or right bundle branch helps differentiate complex supraventricular and fascicular tachycardias into 3 common patterns.
Why the study?
Differentiating various forms of complex supraventricular and fascicular tachycardias, such as AVNRT from concealed nodofascicular tachycardia, presents a common clinical dilemma.
Does recording the activation sequence of the His bundle or right bundle branch improve the diagnosis of complex tachycardia circuits in patients with supraventricular and fascicular tachycardias?
Does recording the activation sequence of the His bundle or right bundle branch improve the diagnosis of complex tachycardia circuits in patients with supraventricular and fascicular tachycardias?
Recording the His to right bundle activation sequence using multipolar catheters is a valuable technique for differentiating complex supraventricular and fascicular tachycardias.

May aid EP lab differentiation of complex tachycardias; leaves open prospective validation before routine use.
Viswanathan et al. (2021) conducted a review in Complex Tachycardia Circuits. Recording the activation sequence of the His bundle or right bundle branch was evaluated. Recording the activation sequence of the His bundle or right bundle branch helps differentiate complex supraventricular and fascicular tachycardias into 3 common patterns.
