This report describes the clinical, laboratory, and electrophysiologic features of 52 patients with ventricular tachycardia (VT) who had no clinical evidence heart disease. The mean age was 36 years, cardiovascular collapse occurred in 18 (35%), exercise-related symptoms were present 24 49 (49%). There 20 sustained monomorphic VT, 11 incessant 21 nonsustained VT. Abnormalities 14 38 (37%) during echocardiography 47 (45%) underwent cardiac catheterization. During baseline evaluation while not...
Background— Atrial fibrillation (AF) is the most common sustained arrhythmia observed in otherwise healthy individuals. Most lone AF cases are nonfamilial, leading to assumption that a primary genetic origin unlikely. In this study, we provide data supporting novel paradigm atrial tissue–specific defects may be associated with sporadic of AF. Methods and Results— We sequenced entire coding region connexin 43 (Cx43) gene ( GJA1 ) from tissue lymphocytes 10 unrelated subjects who had undergone...
Introduction Sarcoidosis is a granulomatous disease of unknown etiology, which involves the heart in 5–25% cases. Although ventricular tachycardia (VT) has been reported as first presentation sarcoidosis, its prevalence not previously investigated. In this prospective study, we sought to systematically investigate cardiac sarcoidosis (CS) patients presenting with monomorphic VT (MMVT) and no previous history sarcoidosis. Methods Consecutive MMVT tertiary care center were screened for...
Proarrhythmic effects of flecainide acetate have been reported during exercise, but the mechanism for arrhythmogenic interaction between and exercise is unknown. We hypothesized that sinus tachycardia may enhance flecainide-induced conduction slowing by increasing use-dependent sodium channel blockade, thereby facilitating occurrence ventricular reentry. To evaluate modulation flecainide's we studied 19 patients who were receiving therapeutic doses treatment cardiac arrhythmias. Sixteen...
The three-dimensional contributions to human atrial activation in sinus rhythm have not been specifically characterized. We evaluated the sequence of endocardial and epicardial voltage atria during normal rhythm.The study group includes 35 patients with history symptomatic fibrillation. Prior catheter ablation fibrillation, we performed multielectrode electroanatomic mapping rhythm, endocardially RA, LA, coronary (CS) and, 10 patients, epicardially transverse oblique sinus. Following region...
The relative contribution of the atrial septum and interatrial connections to biatrial activation is a fundamental concept human cardiac electrophysiology that has yet be fully characterized. purpose present study was determine how both atria are coupled electrically.Twenty patients (16 men; mean age 54+/-11years) with history symptomatic fibrillation (AF) underwent simultaneous noncontact mapping before catheter ablation AF. multiple electrode array catheters were positioned, respectively,...
Background: It has been suggested that remote magnetic navigation (RMN) may provide enhanced catheter stability and substrate contact to aid in ablation. To date, no study examined this claim. Accordingly, we compared the characteristics of successful ablation atrioventricular reentry tachycardia (AVNRT) using RMN with a matched population ablated conventional (CON) manual approach. Methods: Sixteen patients who underwent RMN‐assisted typical AVNRT were 16 had CON‐AVNRT Results: All slow...
