亚临床右室疾病的诊断,对患有右室源性室速并且无明显心脏异常的患者,甚为重要。因为,右室心肌病或右室心肌发育不良的存在均可致室速治疗的预后不良。早期甄别出这些患者,及时予恰当的抗心律失常药物治疗或植入埋入式除颤器或可改善其长期预后。本文旨在研究:室速的心电图特点、信号平均心电图及右室超声心动图,与亚临床右室疾病(经右室心内膜活组织检查证实)间的关系。 方法 研究对象为27例慢性室速患者
The diagnosis of subclinical right ventricular disease is important for patients with right ventricular-derived VT and no significant cardiac abnormalities. Because, right ventricular cardiomyopathy or right ventricular dysplasia can cause ventricular tachycardia poor prognosis. Early screening of these patients, timely treatment with appropriate antiarrhythmic drugs or implantation of defibrillators or can improve its long-term prognosis. The purpose of this paper is to study the relationship between VT ECG characteristics, signal-averaged ECG and RV echocardiography, and subclinical RV disease (confirmed by right ventricular endocardial biopsy). Methods The subjects were 27 patients with chronic ventricular tachycardia
