Altered Calcium Handling and Ventricular Arrhythmias in Acute Ischemia
, 2016 Acute ischemia results in deadly cardiac arrhythmias that are a major contributor to sudden cardiac death (SCD). The electrophysiological changes involved have been extensively studied, yet the mechanisms of ventricular arrhythmias during acute ischemia ...

Idiopathic Ventricular Tachycardia: Transcatheter Ablation or Antiarrhythmic Drugs? [PDF]
, 2015 INTRODUCTION: Ventricular tachycardia or frequent premature ventricular contractions (PVCs) can occur in the absence of any detectable structural heart disease. In this clinical setting, these arrhythmias are termed idiopathic.

Role of the Purkinje system in heritable arrhythmias
, 2019 Much has been written about arrhythmias in structurally normal hearts. In this review, we focus on rapid ventricular arrhythmias that occur in hearts having a pathogenic genetic variant that has been found in families in which arrhythmias occur.

Idiopathic Submitral Left Ventricular Aneurysm: an Unusual Substrate for Ventricular Tachycardia in Caucasians [PDF]
, 2005 Annular submitral aneurysms have been rarely reported in Caucasians. They are typically diagnosed in non-white adults who present with severe mitral regurgitation, heart failure, systemic embolism, ventricular arrhythmias, and sudden cardiac death.

Natural history of idiopathic ventricular arrhythmias in children
In a Good Rhythm, 2017 Idiopathic ventricular arrhythmia in children is usually benign. Ventricular ectopy in children usually is an incidental finding. Prevalence varies with age: neonates nearly 20%, school age 10%, teenagers 20-30%. During natural history total or partial disappearance of idiopathic ventricular ectopy, spontaneously or after treatment was described in ...

The “Dead-End Tract” and Its Role in Arrhythmogenesis
Journal of Cardiovascular Development and Disease, 2016 Idiopathic outflow tract ventricular arrhythmias (VAs) represent a significant proportion of all VAs. The mechanism is thought to be catecholamine-mediated delayed after depolarizations and triggered activity, although other etiologies should be ...

Idiopathic ventricular arrhythmias arising from the left ventricular outflow tract: Tips and tricks
Journal of Arrhythmia, 2014 Idiopathic left ventricular outflow tract ventricular arrhythmias (LVOT-VAs) arising from the LVOT are rare compared with the VAs arising from the RVOT. Idiopathic LVOT-VAs have been divided into four subgroups based on successful catheter ablation sites:

Clinical and Electrophysiological Spectrum of Idiopathic Ventricular Outflow Tract Arrhythmias
Journal of the American College of Cardiology, 2007 This study sought to compare and contrast the clinical and electrophysiological characteristics of outflow tract arrhythmias.Idiopathic ventricular outflow tract arrhythmias manifest clinically in 3 forms: 1) paroxysmal sustained monomorphic ventricular tachycardia (SMVT), 2) repetitive nonsustained ventricular tachycardia (NSVT), or 3) premature ...

Arrhythmogenic Right Ventricular Cardiomyopathy: Prognostic Value of Electroanatomic Voltage Mapping [PDF]
, 2013 Background: Endocardial voltage mapping (EVM) identifies low-voltage right ventricular (RV) areas, which may represent the electroanatomic scar substrate of life-threatening tachyarrhythmias.
