Left bundle branch pacing: An evolving site for physiological pacing

Journal of Arrhythmia, 2021
For patients with symptomatic bradyarrhythmia, cardiac pacing is the only appropriate treatment option. Electrical and mechanical dyssynchrony caused by traditional right ventricular apical pacing leads to left ventricular dysfunction and atrial ...

Visualization of Left Ventricular Endocardium Activation Time during Cardiac Conduction System Pacing

Український журнал серцево-судинної хірургії, 2023
Introduction. Right ventricular myocardial pacing leads to asynchronous contraction of the left ventricle (LV) and can impair its contractility over time.

Comparison of left ventricular and biventricular pacing: Rationale and clinical implications

Anatolian Journal of Cardiology, 2019
Cardiac resynchronization therapy constitutes a cornerstone in advanced heart failure treatment, when there is evidence of dyssynchrony, especially by electrocardiography.

Assessment of Ventricular Pacing in the Setting of an Institutional Improvement Program: Insights into Physiological Pacing

Clinical Medicine Insights: Cardiology, 2012
Background Excessive ventricular pacing is known to be detrimental. The purpose of this study was to assess ventricular pacing in the setting of an institutional improvement program in order to decrease unnecessary pacing.

Cardiomyopathy Induced by Artificial Cardiac Pacing: To Whom, When, Why, and How? Insights on Heart Failure Development

Brazilian Journal of Cardiovascular Surgery, 2022
Coordinated and harmonic (synchronous) ventricular electrical activation is essential for better left ventricular systolic function. Intraventricular conduction abnormalities, such as left bundle branch block due to artificial cardiac pacing, lead to ...

Electrical interventricular delay and left ventricular delay in right ventricular pacemaker pacing before upgrading to cardiac resynchronization therapy

Current Directions in Biomedical Engineering, 2017
Cardiac resynchronization therapy with biventricular pacing is an established therapy for heart failure patients with sinus rhythm, reduced left ventricular ejection fraction and electrical ventricular desynchronization.

Case presentation: implantation of cardiac resynchronization therapy pacemaker via the coronary sinus in a patient with triple valve replacement

BMC Cardiovascular Disorders, 2018
Background In patients with triple valve replacement developing third-degree atrioventricular block (AVB), the most appropriate approach for permanent pacemaker implantation remains questionable.

Successful resynchronization by permanent His-bundle pacing in a patient with pacing-induced cardiomyopathy

Journal of Arrhythmia, 2016
Right ventricular (RV) pacing has been reported to result in ventricular dyssynchrony, heart failure, and increased mortality. Pacing associated deterioration of left ventricular (LV) systolic function has been termed pacing-induced cardiomyopathy (PICM).

Physiological cardiac pacing: Current status

Indian Heart Journal, 2016
Adverse hemodynamics of right ventricular (RV) pacing is a well-known fact. It was believed to be the result of atrio-ventricular (AV) dyssynchrony and sequential pacing of the atrium and ventricle may solve these problems.

Impulse data models for the inverse problem of electrocardiography [PDF]

, 2021
The proposed method re-frames traditional inverse problems of electrocardiography into regression problems, constraining the solution space by decomposing signals with multidimensional Gaussian impulse basis functions. Impulse HSPs were generated with single Gaussian basis functions at discrete heart surface locations and projected to corresponding ...
