Radiofrequency Catheter Ablation of Atrioventricular Nodal Reentrant Tachycardia: It Is Not Always As It Is Expected [PDF]

Indian Pacing and Electrophysiology Journal, 2004
Observation of Coincident arrhythmias is not uncommon but the co-existence of idiopathic verapamil sensitive left ventricular tachycardia (ILVT) with other arrhythmias is very rare.

Idiopathic Ventricular Arrhythmias Originating from the Left Ventricular Summit: A Diagnostic and Therapeutic Challenge. [PDF]

J Clin Med
Premature ventricular contractions (PVCs) originating from the left ventricular summit (LVS) present a diagnostic and therapeutic challenge due to their complex anatomical location. The LVS includes an epicardial area of the left ventricle bordered by major coronary arteries, which has been increasingly recognized as an arrhythmic focus.

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 ...

Arrhythmias in Patients With Valvular Heart Disease: Gaps in Knowledge and the Way Forward

Frontiers in Cardiovascular Medicine, 2022
The prevalence of both organic valvular heart disease (VHD) and cardiac arrhythmias is high in the general population, and their coexistence is common. Both VHD and arrhythmias in the elderly lead to an elevated risk of hospitalization and use of health ...

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 ...

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 ...

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 ...

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.

Catheter ablation of symptomatic idiopathic ventricular arrhythmias : A five-year single-centre experience. [PDF]

Neth Heart J, 2018
Aims: This study was designed to gain insight into the patient characteristics, results and possible complications of ablation procedures for symptomatic idiopathic premature ventricular complexes (PVC) and idiopathic ventricular tachycardia (VT ...
