Catheter Ablation of Idiopathic Ventricular Arrhythmias.

Heart, Lung and Circulation, 2019
Ventricular arrhythmias (VA) are observed in the setting of structural heart disease. However, in a proportion of patients presenting with VT, the routine diagnostic modalities fail to demonstrate overt myocardial abnormality. These arrhythmias have been

QRS morphology in lead V1 for the rapid localization of idiopathic ventricular arrhythmias originating from the left ventricular papillary muscles: A novel electrocardiographic criterion

Heart Rhythm, 2020
BACKGROUND 12-lead electrocardiogram (ECG) criteria have been developed to identify idiopathic ventricular arrhythmias (VAs) from the left ventricular (LV) papillary muscles (PAPs), but accurate localization remains a challenge.

How to use the 12-lead ECG to predict the site of origin of idiopathic ventricular arrhythmias

Heart Rhythm, 2019
Idiopathic ventricular arrhythmias may arise from anywhere in the heart, and the majority of them can be effectively treated with catheter ablation. The 12-lead electrocardiogram (ECG) is the initial mapping tool to predict the most likely site of origin

Clinical and electrophysiological characteristics of idiopathic ventricular arrhythmias originating from the slow pathway region

Heart Rhythm, 2019
BACKGROUND The slow pathway region (SPR) is commonly targeted during ablation of atrio-ventricular nodal reentrant tachycardia. However, its role in idiopathic ventricular arrhythmias (IVAs) remains unknown.
