Attenuation of stretch-induced arrhythmias following chemical ablation of Purkinje fibres, in isolated rabbit hearts

Frontiers in Physiology, 2023
Purkinje fibres (PFs) play an important role in some ventricular arrhythmias and acute ventricular stretch can evoke mechanically-induced arrhythmias. We tested whether Purkinje fibres, play a role in these arrhythmias.

Non-compaction cardiomyopathy – brief review [PDF]

, 2017
Left ventricular non-compaction cardiomyopathy is a genetic disorder characterized by the presence of two myocardial layers with numerous prominent trabeculations and deep inter-trabecular recesses that communicate with the ventricular cavity.

Sex and Gender Differences in Ventricular Arrhythmias

US Cardiology Review, 2023
Ventricular arrhythmias, including ventricular tachycardia and VF, commonly occur in patients with underlying cardiomyopathy. Sex differences exist in almost every aspect of ventricular arrhythmia from epidemiology, anatomy, and physiology to management ...

Identification of Myocardial Disarray in Patients With Hypertrophic Cardiomyopathy and Ventricular Arrhythmias

Journal of the American College of Cardiology, 2019
Background Myocardial disarray is a likely focus for fatal arrhythmia in hypertrophic cardiomyopathy (HCM). This microstructural abnormality can be inferred by mapping the preferential diffusion of water along cardiac muscle fibers using diffusion tensor

Ventricular arrhythmias in Chagas disease

Revista da Sociedade Brasileira de Medicina Tropical, 2015
Sudden death is one of the most characteristic phenomena of Chagas disease, and approximately one-third of infected patients develop life-threatening heart disease, including malignant ventricular arrhythmias.

Differentiating Right- and Left-Sided Outflow Tract Ventricular Arrhythmias.

Circulation: Arrhythmia and Electrophysiology, 2019
Idiopathic ventricular arrhythmias commonly originate from the right ventricular and left ventricular outflow tracts (OTs). Advances in real-time imaging have refined our understanding of the intimate anatomic structures implicated in the genesis of OT ...
