Risk factors for recurrent ventricular arrhythmias in patients with idiopathic ventricular fibrillation [PDF]

Journal of Cardiovascular Electrophysiology, 2020
Sudden Cardiac Death (SCD) remains a global threat.1The most common causes of SCD are ischemic heart diseases and structural cardiomyopathies in the elderly. Additional causes can be arrhythmogenic, respiratory, metabolic, or even toxigenic.2,3,4 Despite the novel diagnostic tools and our deeper understanding of pathologies and genetic associations ...

Electrophysiologic and imaging evidence for an occult myopathic substrate in patients with idiopathic ventricular arrhythmias

, 2021
Background: Idiopathic VA are traditionally considered benign, although occasional patients develop an ectopy-mediated cardiomyopathy (EMC). It is unclear whether patients with idiopathic VA in the absence of left ventricular (LV) dysfunction harbor a ...

Monomorphic Ventricular Arrhythmias in Athletes [PDF]

, 2019
Ventricular arrhythmias are challenging to manage in athletes with concern for an elevated risk of sudden cardiac death (SCD) during sports competition. Monomorphic ventricular arrhythmias (MMVA), while often benign in athletes with a structurally normal

Idiopathic ventricular arrhythmia arising from the mitral annulus: a distinct subgroup of idiopathic ventricular arrhythmias.

Journal of the American College of Cardiology, 2005
We sought to clarify the prevalence and characteristics of idiopathic ventricular tachycardia or premature ventricular contraction originating from the mitral annulus (MAVT/PVC).Recent case reports have presented patients with MAVT/PVC.Electrocardiographic (ECG) characteristics and the results of electrophysiologic investigation and radiofrequency ...

A K_ATP channel opener inhibited myocardial reperfusion action potential shortening and arrhythmias [PDF]

, 2001
Low concentrations of certain K_ATP channel openers have been reported to exert a moderate inhibitory effect on arrhythmias during post-ischaemic early myocardial reperfusion, but the accompanying effects on the time course of ...

Ventricular arrhythmias in idiopathic dilated cardiomyopathy. [PDF]

Heart, 1984
Twenty four hour ambulatory electrocardiograms were recorded in 60 patients with idiopathic dilated cardiomyopathy. The diagnosis was based on clinical, laboratory, and cardiac catheterisation findings. All patients had a left ventricular ejection fraction less than 0.55; in 39 it was less than 0.40.

Idiopathic Ventricular Arrhythmia Originating From the Cardiac Crux or Inferior Septum [PDF]

Circulation: Arrhythmia and Electrophysiology, 2014
Background— Idiopathic ventricular arrhythmia (VA) can arise from the epicardium near the posteroseptal region (cardiac crux). There are only 2 prior reports describing idiopathic VA from the cardiac crux. The purpose of this study was to characterize the clinical and the electrocardiographic features of idiopathic crux VA.

Anatomical Consideration in Catheter Ablation of Idiopathic Ventricular Arrhythmias [PDF]

Arrhythmia & Electrophysiology Review, 2016
Idiopathic ventricular arrhythmias (VAs) are ventricular tachycardias (VTs) or premature ventricular contractions (PVCs) with a mechanism that is not related to myocardial scar. The sites of successful catheter ablation of idiopathic VA origins have been progressively elucidated and include both the endocardium and, less commonly, the epicardium ...

Tachycardia-Induced Cardiomyopathy in Patients With Idiopathic Ventricular Arrhythmias: The Incidence, Clinical and Electrophysiologic Characteristics, and the Predictors

, 2011
Idiopathic Ventricular Arrhythmias and Cardiomyopathy. Introduction: Idiopathic ventricular arrhythmias in the form of monomorphic premature ventricular contractions (PVC) and/or ventricular tachycardia (VT) can cause tachycardia-induced cardiomyopathy ...
