AI Article Synopsis
- * A specific case showed that correcting intrinsic RBBB can be achieved by targeting the intra-Hisian left bundle branch (LBB) with different output settings.
- * LBB pacing offers a significant advantage by maintaining synchrony with a lower threshold, suggesting it may be a safe and effective option for patients with high-grade atrioventricular (AV) block and RBBB.
Article Abstract
In patients with preserved ejection fraction or right bundle branch block (RBBB) pattern requiring a high percentage of ventricular pacing, His-bundle pacing (HBP) might be an alternative to biventricular pacing, although the high threshold occasionally occurs. We provided a case of the intrinsic RBBB correction by capturing intra-Hisian left bundle branch (LBB) or distal His-bundle with different output settings. LBB pacing had the advantage of a much lower threshold while remained most synchrony as HBP. LBB pacing might be a promisingly safe and effective procedure for patients with high-grade atrioventricular (AV) block and RBBB pattern.

Patients presenting with suspected acute coronary syndrome (ACS) in the emergency department (ED) require rapid and accurate electrocardiographic (ECG) evaluation. This study aims to assess conventional ECG markers for diagnosing non-ST-elevation ACS (NSTE-ACS) in patients with chest discomfort and right bundle branch block (RBBB). A nested case-control design was employed to compare patients with RBBB admitted to the ED for suspected cardiac ischemia, focusing on those who developed NSTE-ACS versus those who did not.

Transthyretin Cardiac amyloidosis (ATTR-CA) is an increasingly recognised cause of heart failure in our elderly patients with preserved ejection fraction. Patients with ATTR-CA who require permanent pacemaker implantation often have preserved ejection fraction and do not meet the clinical indication for cardiac resynchronization therapy (CRT). In these patients, left bundle branch area pacing (LBBAP) can be a reasonable option to maximise physiological activation of the left ventricle.

Background: Non-response to cardiac resynchronization therapy (CRT) is an important issue in the treatment of heart failure with reduced ejection fraction (HFrEF) and non-left bundle branch block (LBBB). Electrocardiogram-gated myocardial perfusion single-photon emission computed tomography imaging (G-MPI SPECT) is typically used to assess left ventricular (LV) dyssynchrony. This study aimed to determine whether G-MPI parameters are associated with non-responsiveness to CRT.

Left bundle branch pacing (LBBP) is an emerging physiological pacing technique characterized by stable pacing parameters and a narrower QRS duration. This study aims to compare the long-term efficacy and safety of biventricular pacing (BIVP) and LBBP in patients with heart failure with reduced ejection fraction (HFrEF) and complete left bundle branch block (CLBBB). A retrospective analysis was conducted on 35 patients with chronic HFrEF accompanied by CLBBB treated at our center from April 2018 to October 2022.

Background: Left bundle branch block (LBBB) is a rare conduction disorder in athletes associated with ventricular dyssynchrony, which can lead to left ventricular systolic dysfunction and exercise intolerance. Inappropriate sinus tachycardia (IST) is characterized by an excessive heart rate (HR) that is not related to physiological needs, often resulting in reduced exercise capacity. Managing these conditions in athletes can be challenging, as standard treatments like beta-blockers and ivabradine, while effective in controlling HR, are described to be associated with a reduction in maximal exercise performance.
