Speckle-tracking echocardiography elucidates the effect of pacing site on left ventricular synchronization in the normal and infarcted rat myocardium.

PLoS ONE, 2014
BackgroundRight ventricular (RV) pacing generates regional disparities in electrical activation and mechanical function (ventricular dyssynchrony). In contrast, left ventricular (LV) or biventricular (BIV) pacing can improve cardiac efficiency in the ...

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).

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 ...

Mechanical and Electrical Phenotype of hiPSC‐Cardiomyocytes on Fibronectin‐Based Hydrogels

Advanced Healthcare Materials, EarlyView.
We introduce fibronectin‐based PEG hydrogels with controlled rigidity to enable the culture of iPSC‐derived cardiomyocytes. These substrates offer an alternative to the current culture of these cells on fibronectin‐coated glass, providing enhanced structural and functional behavior. The system provides a more physiologically relevant platform to assess

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

Single-chamber Versus Dual-chamber Implantable Cardioverter Defibrillators: Do We Need Physiologic Pacing in The Course? [PDF]

, 2006
Background: Many patients with ICD receive different antiarrhythmic drugs (e.g. sotalol, amiodarone, β-blockers) because of ventricular or atrial tachycardias.

Tapered Pillar Design for High‐Precision Force Readout in Miniaturized Engineered Heart Tissues From Human Pluripotent Stem Cells

Advanced Healthcare Materials, EarlyView.
Engineered heart tissues (EHTs) are a valuable approach in capturing human cardiac physiology and drug responses in vitro. Here, a novel tapered pillar design is developed in an EHT platform to confine tissues in a predefined position‐ at the middle of the pillar height.

Does Minimizing Ventricular Pacing Reduce the Incidence of Atrial Fibrillation? A Systematic Review and Meta-analysis of Randomized Controlled Trials

Cardiovascular Innovations and Applications, 2020
Background: Right ventricular pacing disrupts atrioventricular synchrony and increases the risk of atrial fibrillation (AF). However, whether algorithms for minimizing ventricular pacing reduce the incidence of AF remains controversial.

Changes of Sympathetic Activity in Patient with Chronic Atrial Fibrillation and Severe Congestive Heart Failure Treated with Biventricular Pacing

Journal of Arrhythmia, 2006
The patient was a 64-year-old man with chronic atrial fibrillation with bradycardia. Left ventricular ejection fraction was 34%. He was treated with biventricular pacing. Heart failure improved from NYHA class III to II.
