Mode of Onset of Malignant Ventricular Arrhythmias in Idiopathic Ventricular Fibrillation

Journal of Cardiovascular Electrophysiology, 1997
Mode of Onset of Idiopathic VF. Introduction: The mode of onset of malignant ventricular arrhythmias (ventricular tachycardia [VT] or ventricular fibrillation [VF] has been well described in patients with organic heart disease and in patients with the long QT syndromes. Less is known about the mode of onset of VF in patients with out‐of‐hospital VF who

Sex differences in idiopathic ventricular arrhythmias

, 2020
Idiopathic ventricular arrhythmias (VAs), including ventricular tachycardias (VTs) and premature ventricular contractions, represent approximately 10% of VAs in clinical practice. The VAs arising from the right ventricular outflow tract in women were 1.5–

Mapping and catheter ablation of idiopathic ventricular arrhythmias

, 2020
Ventricular arrhythmias (VAs) in patients with apparently no structural heart disease represent approximately 10% of all ventricular tachycardia (VT) diagnoses and are called idiopathic VA.

Sex Difference in Catheter Ablation of Idiopathic Ventricular Arrhythmias and Ventricular Arrhythmias Associated with Structural Heart Disease

Current Cardiovascular Risk Reports, 2020
Sex differences in clinical manifestations, electrophysiological properties and treatment of ventricular arrhythmias (VA) have been an area of research in the last years. In this review, we focus on sex differences in the catheter ablation of VA in patients with and without structural heart disease. Women have more frequently RVOT than LVOT PVC/VTs but

Electroanatomic Localization of Idiopathic Ventricular Arrhythmia Origins in the Left Ventricular Outflow Tract.

Heart Rhythm
Idiopathic ventricular arrhythmias (VAs) originate from endocardial as well as epicardial or intramural sites in the left ventricular outflow tract (LVOT).

Ablation for idiopathic ventricular arrhythmia – with and without arrhythmia-induced cardiomyopathy

Scandinavian Cardiovascular Journal, 2014
We conducted a study to assess the procedural success and long-term freedom from arrhythmia in patients treated with radiofrequency ablation (RFA) for idiopathic ventricular arrhythmia (VA) with and without arrhythmia-induced cardiomyopathy (AIC).We identified 131 patients treated with RFA for idiopathic VA in our institution; 16 of whom had AIC.

Electrocardiographic landmarks of idiopathic ventricular arrhythmia origins

Heart, 2019
Idiopathic ventricular arrhythmias occur in the absence of underlying structural heart disease and less commonly in the presence of coexistent, but mechanistically unrelated, myocardial scar. These arrhythmias originate from several anatomical sites in both ventricles, with a predilection in outflow tract structures.

Significance of ventricular arrhythmias in idiopathic dilated cardiomyopathy

The American Journal of Cardiology, 1984
The incidence and prognostic significance of ventricular arrhythmias identified by 24-hour ambulatory electrocardiography (Holter) was prospectively assessed in 74 patients with idiopathic dilated cardiomyopathy (IDC). The criteria for diagnosis of IDC were based on clinical and cardiac catheterization findings.

Trends Favoring an Anatomical Approach to Radiofrequency Catheter Ablation of Idiopathic Ventricular Arrhythmias Originating From the Left Ventricular Summit

Circulation: Arrhythmia and Electrophysiology
BACKGROUND: Epicardial radiofrequency catheter ablation (RFCA) of idiopathic ventricular arrhythmias (VAs) originating from the left ventricular summit (LVS) is challenging because of the anatomic barriers.

Prevalence and electrocardiographic and electrophysiological characteristics of idiopathic ventricular arrhythmias originating from the septal left ventricular summit

Cardiovascular Electrophysiology
The left ventricular summit (LVS) is the highest point on the epicardial surface of the left ventricle. A part of the LVS that is located between the left coronary arteries (lateral‐LVS) is one of the major sites of idiopathic ventricular arrhythmia (VA)
