Abstract
- Since the introduction of left bundle branch pacing (LBBP), a search for precise parameters confirming successful capture of conduction system was conducted. Most of the proposed electrocardiographic criteria refer to patients with narrow QRS complexes. We present a patient with heart failure in whom cardiac resynchronization was achieved using conduction system pacing. While measuring left ventricular activation time, an isoelectric interval of 74 ms between stimulus and R-wave appeared resulting in prolongation of V6 RWPT to 124 ms. Considering the immediate narrowing of QRS complexes following LBBP, the observed latency most probably reflects prolonged conduction time through the His-Purkinje system.<br />Competing Interests: Declaration of competing interest None.<br /> (Copyright © 2024.
