The profiles of ventricular tachrrhythmias with left bundle branch block in patients with arrhythmogenic right ventricular cardiomyopathy
摘要
Abstract
Objective To evaluate the features of ventricular arrhythmias with left bundle branch block in arrhythmogenic right ventricular cardiomyopathy (ARVC) patients.Methods Forty subjects fulfilling the modified task force criteria and 20 patients right ventricular outflow tract tachycardia were included.Information on clinical presentation,12-lead electrocardiography and Fontaine electrocardiographic were evaluated.Results The mean onset age was (32.2 ±12.7)years,as male in predominance (85.0％).Palpitation was the most frequent symptom (82.5％),followed by chest pain (25.0％) and syncope (22.5％).T-wave inversion was the most common presenting abnormality on resting 12-lead ECG (75.0％),followed by localized QRS prolongation (45.0％) and epsilon waves (35.0％).Ventricular tachycardia with left bundle branch block morphology was subsequently documented in a 28 subjects (70.0％) during a study period.T-wave inversion (53.0％) in V1 ～ V3 leads was the most common presenting abnormality in patients of ventricular tachycardia with left bundle branch block morphology,followed by late potentials on signal-averaged ECG.Comparing with right ventricular outflow tachycardia patients,significantly prolonged QRS duration was observed (P ＜0.05),with significantly later precordial transition in V6 lead (P ＜ 0.05) in ARVC patients.Conclusion There were significantly differences between right ventricular outflow tract arrhythmias originating from ARVC and right ventricular outflow tract tachycardia patients.关键词
