Response of mean arterial pressure to temporary biventricular pacing after chest closure during cardiac surgery [PDF]

, 2012
ObjectivesWe have previously demonstrated that biventricular pacing increased cardiac output within 1 hour of weaning from cardiopulmonary bypass in selected patients. To assess the possible sustained benefit, we reviewed in the present study the effects

QT Interval Evaluation in Right Ventricular Pacing: Validation of a Novel Formula

Pacing and Clinical Electrophysiology, Volume 49, Issue 10, Page 1455-1463, October 2026.
ABSTRACT Background QT interval measurement in the presence of right ventricular pacing (RVP) represents a clinical challenge. We therefore aimed to derive and validate a formula for QT estimation during RVP in a large cohort of pacemaker patients. Methods and Results We prospectively enrolled 100 patients in a derivation cohort and 487 in a validation

Effect of Biventricular Pacing on Diastolic Dyssynchrony

Journal of the American College of Cardiology, 2010
This study sought to examine the changes in diastolic dyssynchrony with cardiac resynchronization therapy (CRT).Little is known about the effect of CRT on diastolic dyssynchrony.Consecutive heart failure patients (n = 266, age 65.7 ± 10.0 years) underwent color-coded tissue Doppler imaging at baseline, 48 h, and 6 months after CRT.

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.

Echocardiographic Substrate for Biventricular Pacing

Journal of the American College of Cardiology, 2015
It is axiomatic that the presence of a substrate that is amenable to a specific treatment, coupled with effective delivery of that treatment, is likely to produce the most favorable clinical outcomes.

Improvement in Clinical Outcomes With Biventricular Versus Right Ventricular Pacing The BLOCK HF Study [PDF]

, 2016
BackgroundSustained right ventricular (RV) apical pacing may lead to deterioration in ventricular function and an increased risk of heart failure, especially in patients with pre-existing systolic dysfunction.

Presentation of preload and afterload to isolated heart preparations

The Journal of Physiology, Volume 604, Issue 17, Page 7025-7044, 1 September 2026.
Abstract figure legend The heart can be isolated, and when this is so, it must be subjected to loading conditions. Over the past few decades, various loading methods have been developed to prescribe preload and afterload to isolated working‐heart preparations.

ST-elevation during biventricular pacing [PDF]

Europace, 2011
Pacemakers devaluate the accuracy of the electrocardiogram (ECG) for the diagnosis of myocardial ischaemia. We present the case of a 53-year-old man with ischaemic cardiomyopathy and acute chest pain. Besides biventricular pacing, new ST-segment elevations were present leading to the diagnosis of myocardial infarction.
