Coexistence of atrioventricular accessory pathways and drug‐induced type 1 Brugada pattern

Abstract

DI-Type1-BrP is relatively common in patients with AV-APs. We identify 12-lead ECG characteristics during preexcitation and orthodromic AVRT that point to an underlying type1-BrP, portending an increased probability for development of malignant arrhythmias.
