Acute Reduction in Blood Flow in the Right Coronary Artery After PCI Facilitates Pacemaker‐Induced Ventricular Fibrillation

Annals of Noninvasive Electrocardiology, Volume 31, Issue 1, January 2026.
We present a case involving pacemaker sensing dysfunction caused by acute reduction in blood flow in the right coronary artery. The pacing spikes occurred progressively earlier on the T waves, eventually resulting in R‐on‐T pacing that triggered VF. ABSTRACT Asynchronous pacing itself does not directly lead to the development of malignant ventricular ...

Safety and Efficacy of Aveir Leadless Pacemaker in Chinese Patients

Annals of Noninvasive Electrocardiology, Volume 31, Issue 1, January 2026.
The application of Aveir, as a newly approved leadless pacemaker (LP), in the Chinese population remains limited. This retrospective study aimed to evaluate the safety and efficacy of the Aveir LP in Chinese patients. ABSTRACT Background Aveir, as a newly approved leadless pacemaker (LP), has been increasingly adopted in clinical practice. However, its

Analysis of Diagnostic Clues in a Rare Case of Ventricular Preexcitation Masking Occlusive Myocardial Infarction of the Left Anterior Descending Artery

Annals of Noninvasive Electrocardiology, Volume 31, Issue 1, January 2026.
This case report describes a potential electrocardiographic manifestation of ventricular pre‐excitation concealing a typical ST‐segment elevation myocardial infarction and provides a systematic analysis of the underlying pathophysiological mechanisms.

Is Left Bundle Branch Pacing Feasible in Patients With Ventricular Septal Defect?

Annals of Noninvasive Electrocardiology, Volume 31, Issue 1, January 2026.
This report presents two cases of left bundle branch pacing (LBBP) implantation in patients with perimembranous ventricular septal defect (pmVSD) and provides a novel approach to guide lead placement using both angiography and electroanatomic mapping, which ensures accuracy and reduces potential complications.
