Case in brief

This report describes two patients with bradycardia who underwent dual-chamber pacemaker implantation, one receiving left bundle branch area pacing (LBBAP) and the other right ventricular septal pacing (RVSP). UHF-ECG analysis revealed that the LBBAP case maintained low dyssynchrony with minimal changes in QRS duration and ventricular activation indices, while the RVSP case exhibited significant increases in dyssynchrony metrics.

Diagnostic / clinical pearl

UHF-ECG can quantitatively assess ventricular activation synchrony, distinguishing between LBBAP and RVSP, which may have implications for pacing strategy in bradycardia patients.

Why it matters

Understanding the differences in ventricular activation patterns between pacing techniques can guide clinicians in optimizing pacing strategies for better patient outcomes.
