Validation of a clinical model for predicting left versus right ventricular outflow tract origin of idiopathic ventricular arrhythmias [PDF]

open access: yes, 2023
BACKGROUND Prediction of the chamber of origin in patients with outflow tract ventricular arrhythmias (OTVA) remains challenging. A clinical risk score based on age, sex and presence of hypertension was associated with a left ventricular outflow tract

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

open access: yesJournal 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]

open access: yesHeart, 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]

open access: yesCirculation: 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.

Sudden cardiac death in patients with nonischemic cardiomyopathy

open access: yesIndian Heart Journal, 2014
Sudden cardiac death (SCD) is an important cause of mortality worldwide. Although SCD is most often associated with coronary heart disease, the risk of SCD in patients without ischemic heart disease is well-established.

Eccentric Activation Patterns in the Left Ventricular Outflow Tract during Idiopathic Ventricular Arrhythmias Originating From the Left Ventricular Summit.

open access: yesCirculation: Arrhythmia and Electrophysiology, 2019
BACKGROUND Idiopathic ventricular arrhythmias (VAs) originating from the left ventricular summit (LVS) can be ablated from the great cardiac vein and remote endocardial sites.

Variants in the SCN5A Promoter Associated With Various Arrhythmia Phenotypes

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
Background Mutations in the coding sequence of SCN5A, which encodes the cardiac Na+ channel α subunit, have been associated with inherited susceptibility to various arrhythmias.

CLINICAL AND IMMUNOLOGICAL ASPECTS OF ELECTRICAL INSTABILITY OF A STRUCTURALLY UNCHANGED HEART [PDF]

open access: yesAnnals of Mechnikov's Institute, 2018
Introduction. The concept of "idiopathic ventricular arrhythmias" (IVA), i.e. arrhythmias that have arisen in the absence of structural disorders of the heart, is becoming more and more conventional.

QT dispersion on ECG Holter monitoring and risk of ventricular arrhythmias in patients with dilated cardiomyopathy

open access: yesHeart International, 2010
Background. QT dispersion (QTd) is increased in patients with dilated cardiomyopathy. Increased QTd has been associated with the risk of sudden death. We studied: a) the relation between QTd on 12-lead ECG and QTd-ECG Holter; b) the relation between QTd ...

TITERS OF ANTIBODIES TO Β1-ADRENOCEPTOR AND M2 CHOLINERGIC RECEPTORS IN PATIENTS WITH VENTRICULAR ARRHYTHMIAS WITHOUT AN ORGANIC CARDIOVASCULAR DISEASE AND THEIR POSSIBLE CLINICAL SIGNIFICANCE

open access: yesРациональная фармакотерапия в кардиологии, 2015
Aim. To identify the most promising epitopes that simulate various sites β1-adrenergic and M2-cholinergic receptors, and to evaluate their possible contribution to the development and maintenance of cardiac arrhythmias, particularly idiopathic ...
