Dual-Chamber Pacing Is Superior to Ventricular Pacing [PDF]

Circulation, 1998
In the August 1, 1996, issue of Circulation , Connolly et al1 presented their evaluation of current data concerning the use of DDD versus VVI pacing in patients with preserved sinus rhythm. They described a dilemma of DDD/VVI pacing in the following terms: “There are reasons to believe that dual-chamber pacing improves patient tolerance of pacing and ...

Sudden failure of ventricular pacing and recovery in a patient with cardiac sarcoidosis

Journal of Arrhythmia, 2017
A 76-year-old woman with sarcoidosis who had an implantable pacemaker for complete atrioventricular block was admitted with syncope. Electrocardiogram revealed ventricular pacing failure, and a marked rise in the ventricular pacing threshold.

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 ...

An Approach to the Stepwise Management of Severe Mitral Regurgitation with Optimal Cardiac Pacemaker Function

Indian Pacing and Electrophysiology Journal, 2014
Right ventricular apical pacing may cause or worsen mitral regurgitation (MR). Potential mechanisms for this adverse sequelae include intraventricular dyssynchrony, altered papillary muscle function, pacing-induced cardiomyopathy with left ventricular ...

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

Advanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Improvement of Left Ventricular Function by Permanent Direct His-Bundle Pacing in a Case with Dilated Cardiomyopathy

Journal of Arrhythmia, 2006
The patient was a 67-year-old female diagnosed with dilated cardiomyopathy. She had chronic atrial fibrillation (AF) with bradycardia and low left ventricular function (left ventricular ejection fraction (LVEF) 40%). She was admitted for congestive heart

Alternative sites of ventricular pacing: His bundle pacing

Monaldi Archives for Chest Disease, 2020
Since its introduction right ventricular apical (RVA) pacing has been the mainstay in cardiac pacing. However, in recent years there has been an upsurge of interest in permanent His bundle pacing (HBP), given the scientific evidence of the harmful role of dyssynchronous ventricular activation, induced by RVA pacing, in promoting the onset of heart ...

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

Advanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

Effect of His Bundle Pacing on Abnormal Myocardial Fatty Acid and Glucose Metabolism Induced by Right Ventricular Pacing

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Metabolic disorder is noted for pacing‐induced cardiomyopathy. The benefits of His bundle pacing over right ventricular (RV) pacing in preventing pacing‐induced cardiomyopathy from a metabolic perspective are yet to be fully understood. Method

Acute echocardiographic and hemodynamic response to his‐bundle pacing in patients with first‐degree atrioventricular block

Annals of Noninvasive Electrocardiology, 2022
Background Atrial pacing and right ventricular (RV) pacing are both associated with adverse outcomes among patients with first‐degree atrioventricular block (1°AVB).
