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.

Electrocardiographic features, mapping and ablation of idiopathic outflow tract ventricular arrhythmias [PDF]

, 2020
Idiopathic outflow tract ventricular arrhythmias are ventricular tachycardias or premature ventricular contractions presumably not related to myocardial scar or disorders of ion channels.

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 ...

Sudden cardiac death in patients with nonischemic cardiomyopathy

Indian 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.

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

Annals 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.

Regulation of gap junction function; the role of nitric oxide. [PDF]

, 2013
Myocardial ischemia resulting from sudden occlusion of a coronary artery is one of the major causes in the appearance of severe, often life-threatening ventricular arrhythmias.

Variants in the SCN5A Promoter Associated With Various Arrhythmia Phenotypes

Journal 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.

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

Heart 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 ...

Protecting the ischemic heart : pharmacological protection against myocardial ischemia in rats in vivo and in vitro [PDF]

, 2004
Today in Switzerland approximately 40% of all deaths are due to cardiovascular diseases. More than half of these are due to ischemic heart disease. Among the fatal consequences of ischemic heart disease are life-threatening arrhythmias and myocardial ...

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

Рациональная 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 ...
