A novel algorithm increases the delivery of effective cardiac resynchronization therapy during atrial fibrillation: The CRTee randomized crossover trial

Autor: Yahya S. Al Hebaishi, Chris Plummer, Zsolt Bári, Suneet Mittal, Robert W. Stadler, Subham Ghosh, Christopher M. Frank, Ruth N. Klepfer, Shufeng Liu

Cardiac resynchronization therapy (CRT) requires a high percentage of ventricular pacing (%Vp) to maximize its clinical benefits. Atrial fibrillation (AF) has been shown to reduce %Vp in CRT due to competition with irregular intrinsic atrioventricula

Device pacing diagnostics overestimate effective cardiac resynchronization therapy pacing results of the hOLter for Efficacy analysis of CRT (OLÉ CRT) study

Publikováno v: Heart Rhythm. 14(4):541-547

A high percentage of biventricular (BiV) or left ventricular (LV) pacing in cardiac resynchronization therapy (CRT) devices has been associated with superior clinical outcomes. However, the percent ventricular (%V) pacing reported by CRT devices simp

Acute Effects of Biventricular Pacing in Heart Failure Patients with a Normal Ejection Fraction and Mechanical Dyssynchrony

Autor: Ruth N. Klepfer, Kathryn Hilpisch, Fu Chun Chiu, Chia Ti Tsai, Vincent E. Splett, Jiunn Lee Lin, Chih Chieh Yu, Yi-Chih Wang, Ling Ping Lai, Juey-Jen Hwang

Publikováno v: Cardiology. 130:112-119

Objectives: We tested the acute effects of resynchronization in heart failure patients with a normal (>50%) left ventricular (LV) ejection fraction (HFNEF) and mechanical dyssynchrony. Methods: Twenty-four HFNEF patients (72 ± 6 years, 5 male) with

Electrical modalities beyond pacing for the treatment of heart failure

Autor: Richard Cornelussen, Ruth N. Klepfer, Vincent E. Splett, Frits W. Prinzen, Lilian Kornet, Berthold Stegemann

Publikováno v: Heart Failure Reviews, 16(3), 315-325. Springer, Cham
Heart Failure Reviews

In this review, we report on electrical modalities, which do not fit the definition of pacemaker, but increase cardiac performance either by direct application to the heart (e. g., post-extrasystolic potentiation or non-excitatory stimulation) or ind

Acute Electromechanical Effects of Atrioventricular Coupled Pacing in Patients With Heart Failure

Autor: Karen J. Kleckner, Mark F. Aaron, Ronald S. Freudenberger, Melody Labeau, Steve Krueger, Ruth N. Klepfer

Publikováno v: Journal of Cardiac Failure. 14:35-40

Background Postextrasystolic potentiation (PESP) is a property of cardiac tissue whereby two closely timed depolarizations cause the subsequent contraction to be of increased magnitude. Methods and Results Ten subjects were studied in a single-blind
