Kinetics and Disappearance of QRS Transition in Patients Undergoing Left Bundle Branch Pacing – A Novel Method for Classifying Microdislodgement

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction QRS transition during the threshold test is the gold standard for confirming direct capture of the Conduction System in patients with left bundle branch pacing (LBBP). Still, we have limited data on the kinetics of QRS transition over time.

Intermittent Ventricular Pre‐Excitation: Clinical Features and Electrophysiological Properties

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Intermittent ventricular pre‐excitation has long been considered a low‐risk marker for sudden death. Accessory pathways (APs) with high‐risk intermittent antegrade conductive properties may exist, but this still represents a gray area in current guidelines.

Predictive value of isolated very low QRS voltage in tilt-table test for neurally mediated syncope

SAGE Open Medicine
Objective: The cause of syncope is generally determined based on clinical manifestations. There has been little discussion about the value of electrocardiograms for diagnosing neurally mediated syncope.

Association of Risk Factors and Cardiac Outcomes in Patients With Primary Prevention of Sudden Cardiac Death: HINODE Study Sub Analysis

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Primary analysis of the HINODE study revealed that mortality and ventricular tachyarrhythmia event rates for patients with primary prevention of sudden cardiac death in Japan were comparable to those of Western patients. Sub‐analysis aimed to evaluate event rates in relation to accumulated risk factors (RFs) (left ventricular ...
