Rabbit models of heart disease. [PDF]
, 2008 Human heart disease is a major cause of death and disability. A variety of animal models of cardiac disease have been developed to better understand the etiology, cellular and molecular mechanisms of cardiac dysfunction and novel therapeutic strategies ...

The Journal of Physiology, EarlyView.Abstract figure legend This study examines the relationships between activation and repolarization times in epicardial reconstructed unipolar electrograms derived from ECG‐imaging in patients with normal and delayed ventricular activation. In patients with a narrow QRS‐complex, ECG‐imaging reveals significant variability in the activation ...

Myocardial remodeling and bioelectric changes in tachycardia-induced heart failure in dogs
Brazilian Journal of Medical and Biological Research, 2013 In this study, electrical and structural remodeling of ventricles was examined in tachycardia-induced heart failure (HF). We studied two groups of weight-matched adult male mongrel dogs: a sham-operated control group (n=5) and a pacing group (n=5) that ...

Evidence of reverse remodeling after long-term biventricular stimulation for resynchronization in patients with wide QRS selected on the basis of echocardiographic electromechanical delays [PDF]
, 2004 Background. There is increasing evidence that cardiac resynchronization therapy (CRT) may trigger an inverse remodeling process leading to decreased left ventricular (LV) volumes in patients with heart failure and wide QRS. However, it is still important

Prognostic impact of sleep disordered breathing and its treatment in heart failure: an observational study [PDF]
, 2011 1. Abstract 1.1. Aims: Sleep disordered breathing (SDB) may contribute to disease progression in patients with chronic heart failure (CHF). The objective of this observational study was to evaluate whether SDB is a risk factor for mortality in CHF ...

The Journal of Physiology, EarlyView.Abstract figure legend Schematic overview of the study's methodology and key findings. In a preclinical swine model, doxorubicin administration induced cardiotoxicity, characterized by diffuse fibrotic remodelling and altered electrical function, as assessed by magnetic resonance (MR) imaging and electrophysiological mapping.

Potential Proarrhythmic Effects of Biventricular Pacing
Journal of the American College of Cardiology, 2005 Resynchronization therapy involving right ventricular endocardial and left ventricular epicardial pacing improves cardiac output, quality of life, and New York Heart Association functional class in patients with congestive heart failure. Although a great deal of attention has been directed at showing the mechanical benefits and in fine-tuning the ...

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.In this two‐center propensity score–weighted cohort of de novo CRT recipients, left bundle branch area pacing was associated with comparable resynchronization and clinical outcomes to biventricular pacing, with fewer late device‐related complications. ABSTRACT Background Left bundle branch area pacing (LBBAP) has emerged as a promising alternative to ...

Quality of life assessment in heart failure interventions: a 10-year (1996-2005) review. [PDF]
, 2007 The increasing prevalence and poor prognosis associated with heart failure have prompted research to focus on improving quality of life (QoL) for heart failure patients.

A review of multisite pacing to achieve cardiac resynchronization therapy [PDF]
, 2017 Non-response to cardiac resynchronization therapy remains a significant problem in up to 30% of patients. Multisite stimulation has emerged as a way of potentially overcoming non-response.
