Electrocardiographic Characteristics of Escape Rhythm During Complete Atrioventricular Block After Transcatheter Aortic Valve Replacement
Abstract
Background: Complete atrioventricular block (CAVB) following transcatheter aortic valve replacement (TAVR) is primarily attributed to mechanical compression of the penetrating or branching portions of the His bundle, and less commonly, the atrioventricular (AV) node. This study aimed to characterize the electrocardiographic features of stable escape rhythms (ERs) occurring during CAVB after TAVR. Methods: This retrospective study analyzed 12-lead electrocardiograms (ECGs) obtained at three time points: before TAVR (ECG 1), after TAVR but before CAVB (ECG 2), and during CAVB (ECG 3). The ERs on ECG 3 were classified as AV junctional if the rate was 40-60 beats per minute (bpm) and, compared with ECG 2, if the QRS morphology matched in ≥10/12 leads, the QRS duration differed by
