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 ...

Ventricular septal pacing: Optimum method to position the lead

Indian Heart Journal, 2018
Adverse hemodynamics of right ventricular (RV) pacing is known for years. Several studies have revealed that adverse outcomes of RV apical pacing are directly linked to cumulative percentage of ventricular pacing.

Pacemaker-induced atrial fibrillation reconsidered—associations with different pacing sites and prevention approaches

Frontiers in Cardiovascular Medicine
The incidence of atrial fibrillation (AF) is significantly higher in patients with pacemakers than in the general population, which could be due to patient characteristics and the diagnostic tool of the pacemaker in detecting atrial high-rate episodes ...

Ventricular pacing – Electromechanical consequences and valvular function

Indian Pacing and Electrophysiology Journal, 2016
Although great strides have been made in the areas of ventricular pacing, it is still appreciated that dyssynchrony can be malignant, and that appropriately placed pacing leads may ameliorate mechanical dyssynchrony.

A Novel Method for ECG Signal Classification via One-Dimensional Convolutional Neural Network [PDF]

arXiv, 2020
This paper presents an end-to-end ECG signal classification method based on a novel segmentation strategy via 1D Convolutional Neural Networks (CNN) to aid the classification of ECG signals. The ECG segmentation strategy named R-R-R strategy (i.e., retaining ECG data between the R peaks just before and after the current R peak) for segmenting the ...

Permanent Parahisian Pacing

Indian Pacing and Electrophysiology Journal, 2007
Right Ventricular Apical permanent pacing could have negative hemodynamic effects. A physiologic pacing modality should preserve a correct atrio-ventricular and interventricular synchronization.

Minimizing hardware using physiological conduction system pacing: A case

IHJ Cardiovascular Case Reports, 2020
Ventricular activation via the specialized His Purkinje system results in synchronous bi-ventricular contraction with an endocardial to epicardial activation wavefront.

Left ventricular pacing in patients with preexisting tricuspid valve disease

Journal of Arrhythmia, 2019
Background Conventional right ventricular (RV) pacing is increasingly recognised to cause tricuspid valve (TV) injury or dysfunction, in part due to the need to pass the lead through the valve.

Permanent pacemaker dependency in patients with new left bundle branch block and new first degree atrioventricular block after transcatheter aortic valve implantation

Scientific Reports, 2021
Conduction disorders with need for permanent pacemaker (PPM) implantation remain frequent complications after transcatheter aortic valve implantation (TAVI).

Comparison of the Acute Effects of Different Pacing Sites on Cardiac Synchrony and Contraction Using Speckle-Tracking Echocardiography

Frontiers in Cardiovascular Medicine, 2021
Background: Cardiac pacing in patients with bradyarrhythmia may employ variable pacing sites, which may have different effects on cardiac function. Left bundle branch pacing (LBBP) is a new physiological pacing modality, and the acute outcomes on cardiac
