Left ventricular function during and after right ventricular pacing

Journal of the American College of Cardiology, 2004
The aim of this research was to evaluate right ventricular pacing effects on left ventricular function.Right ventricular pacing alters the ventricular activation sequence and reduces left ventricular ejection fraction (EF). It is unclear whether the observed reduction in EF can be completely attributed to the alteration in activation sequence.Twelve ...

Twenty‐four hour continuous transvenous temporary right ventricular pacing in healthy horses [PDF]

Journal of Veterinary Internal Medicine
Background The ability to perform transvenous temporary cardiac pacing (TV‐TP) is critical to stabilize horses with symptomatic bradyarrhythmias. Reports of successful TV‐TP in horses are limited, and only briefly describe short‐term pacing. Objective To

Alternative Right Ventricular Pacing Sites [PDF]

Advances in Clinical and Experimental Medicine, 2015
The main adverse effect of chronic stimulation is stimulation-induced heart failure in case of ventricular contraction dyssynchrony. Because of this fact, new techniques of stimulation should be considered to optimize electrotherapy. One of these methods is pacing from alternative right ventricular sites.The purpose of this article is to review ...

Right Ventricular Outflow Tract Septal Pacing Is Superior to Right Ventricular Apical Pacing [PDF]

Journal of the American Heart Association, 2015
Background The effects of right ventricular apical pacing ( RVAP ) and right ventricular outflow tract ( RVOT ) septal pacing on atrial and ventricular electrophysiology have not been thoroughly compared ...

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.

Acute Hemodynamic Effects of Cardiac Resynchronization Therapy Versus Alternative Pacing Strategies in Patients With Left Ventricular Assist Devices

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background The hemodynamic effects of cardiac resynchronization therapy in patients with left ventricular assist devices (LVADs) are uncharacterized. We aimed to quantify the hemodynamic effects of different ventricular pacing configurations in patients ...

Acute left ventricular dysfunction secondary to right ventricular septal pacing in a woman with initial preserved contractility: a case report

Journal of Medical Case Reports, 2011
Introduction Right ventricular apical pacing-related heart failure is reported in some patients after long-term pacing. The exact mechanism is not yet clear but may be related to left ventricular dyssynchrony induced by right ventricular apical pacing ...

Right Ventricular Pacing [PDF]

Circulation: Arrhythmia and Electrophysiology, 2017
See Article by Cronin et al Implantable cardioverter–defibrillators (ICDs) have been shown to prolong life both in the setting of secondary prevention after a malignant ventricular arrhythmia and primary prevention in patients with a severely reduced left ventricular ejection fraction (LVEF).

Temporary epicardial left ventricular and biventricular pacing improves cardiac output after cardiopulmonary bypass

Journal of Cardiothoracic Surgery, 2012
Background To evaluate, with different pacing modes, acute changes in left ventricular systolic function, obtained by continuous cardiac output thermodilution in various subsets of patients undergoing cardiopulmonary bypass surgery.
