Case report: What course to follow when left bundle branch pacing encounters acute myocardial infarction?

Frontiers in Cardiovascular Medicine, 2022
Compared with traditional right ventricular apical pacing, His-bundle pacing (HBP) provides more physiologic pacing by activating the normal conduction system. However, HBP has some limitations including higher pacing thresholds.

Comparison of the Acute Effects of Different Pacing Sites on Cardiac Synchrony and Contraction Using Speckle-Tracking Echocardiography

Frontiers in Cardiovascular Medicine, 2021
Background: Cardiac pacing in patients with bradyarrhythmia may employ variable pacing sites, which may have different effects on cardiac function. Left bundle branch pacing (LBBP) is a new physiological pacing modality, and the acute outcomes on cardiac

Mapping and Ablating Ventricular Premature Contractions That Trigger Ventricular Fibrillation: Trigger Elimination and Substrate Modification [PDF]

, 2014
Ventricular fibrillation (VF) is a malignant arrhythmia, usually initiated by a ventricular premature contraction (VPC) during the vulnerable period of cardiac repolarization. Ablation therapy for VF has been described and increasingly reported.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
