A thrombin-like serine protease, jararassin-I, was isolated from the venom of Bothrops
jararaca. The protein was obtained in high yield and purity by a single chromatographic step …

Aims This study explores the feasibility of left bundle branch pacing (LBBP) and
characterizes electrocardiogram (ECG) patterns during the pacing in comparison with …

Background In patients with or without left bundle branch block, left bundle branch pacing
(LBBP) can produce near normalization of QRS duration (QRSd). This has recently emerged …

Introduction Left bundle branch pacing (LBBP) is characterized with a low and stable pacing
capture threshold, relatively narrow QRS duration due to fast left ventricular activation, and …

Right ventricular (RV) pacing is the main treatment modality for patients with advanced
atrioventricular (AV) block. Chronic RV pacing can cause cardiac systolic dysfunction and …

Background Chronic right ventricular pacing may contribute to deterioration in left ventricular
ejection fraction (LVEF). The aim of the study was to identify the prevalence of pacing …

Background The novel method of left bundle branch pacing (LBBP) has been reported to
produce a narrower QRS duration and lower pacing threshold than right ventricular outflow …

Background The left bundle branch pacing (LBBP) makes the ventricular depolarization
closer to the physiological state and shortens QRS duration. The purpose of this study is to …
