Intramural Idiopathic Ventricular Arrhythmias Originating in the Intraventricular Septum [PDF]

Circulation: Arrhythmia and Electrophysiology, 2012
Background— Intramural septal idiopathic ventricular arrhythmias have not been described systematically. Methods and Results— In a consecutive group of 93 patients with idiopathic ventricular arrhythmias referred for ablation, the site of origin of ventricular arrhythmias was ...

Effective cardiac resynchronization therapy for an adolescent patient with dilated cardiomyopathy seven years after mitral valve replacement and septal anterior ventricular exclusion

Journal of Cardiothoracic Surgery, 2010
Cardiac resynchronization therapy (CRT) is a new treatment for refractory heart failure. However, most heart failure patients treated with CRT are middle-aged or old patients with idiopathic or ischemic dilated cardiomyopathy.

Contact-force monitoring increases accuracy of right ventricular voltage mapping avoiding “false scar” detection in patients with no evidence of structural heart disease

Indian Pacing and Electrophysiology Journal, 2020
Purpose: Electroanatomical mapping (EAM) could increase cardiac magnetic resonance imaging (CMR) sensitivity in detecting ventricular scar. Possible bias may be scar over-estimation due to inadequate tissue contact.

Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

The Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

Acute and sudden death secondary to cardiac tamponade during anaesthetic recovery in a 21‐year‐old draught mule

Equine Veterinary Education, Volume 38, Issue 10, Page e686-e689, October 2026.
Summary This case report is of educational value and contributes to the literature because it describes a unique death after anaesthesia due to cardiac tamponade from a rare cardiac neoplasm. In trying to diagnose the origin of chronic sinusitis, a geriatric mule mare was anaesthetised and during recovery, died acutely.

Epidemiology of Arrhythmias in Children

Indian Pacing and Electrophysiology Journal, 2008
Unlike the adult population, arrhythmias occur less commonly in childhood. Only 5% of the emergency hospital admissions in the paediatric population is attributed to symptomatic arrhythmias.

10-year follow-up after radiofrequency ablation of idiopathic ventricular arrhythmias from right ventricular outflow tract

Indian Pacing and Electrophysiology Journal, 2016
Background: The aim of this study was to examine the effect of radiofrequency ablation (RFA) of ventricular arrhythmias from right ventricular outflow tract (RVOT) during long-term follow-up.

Dysregulation of Peripheral Blood B Cells and Natural Killer Cells Is Associated With Myocarditis in Idiopathic Inflammatory Myopathies

ACR Open Rheumatology, Volume 8, Issue 9, September 2026.
Objective Idiopathic inflammatory myopathies (IIMs), or myositis, are a group of systemic autoimmune diseases leading to proximal muscle weakness. Myocarditis is a major cause of adverse outcomes. Yet, we know very little about the underlying immunologic processes that are driving myocarditis in the context of IIMs. Methods We performed single‐cell RNA

Night syncope: a case report

Clinical Case Reports, 2017
Key Clinical Message “Idiopathic” ventricular fibrillations are rare and are estimated between 5% and 10% of survivors of hospital cardiac arrest, for at least some of them have as origin, a trigger in the Purkinje fibers. Interventional therapy could be

Maskerading Bundle Branch Block Versus Standard Bifascicular Block: A Prognostic Analysis Results Through Electrophysiological Study

Annals of Noninvasive Electrocardiology, Volume 31, Issue 5, September 2026.
Patients with masked bundle branch block (MBBB) exhibited significantly longer HV intervals than those with standard bifascicular block (66.3 vs. 52.9 ms; p = 0.006), suggesting more advanced His–Purkinje conduction disease. During follow‐up, MBBB was associated with higher rates of atrial fibrillation or flutter (39.5% vs.
