1例持续性室性心动过速(VT)反复发作,伴心源性晕厥患者,心电图、超声心动图、X线心脏摄片均提示心脏扩大。心肌断层显像呈不可逆性、节段性、花斑样稀琉区。心脏电生理检查可见心室晚电位,心室程序刺激可诱发持续性临床型VT。诊断扩张型心肌病,VT。于1991年4月13日安置埋藏式自动复律除颤器,术后3个月自动除颤4次,有效地防止了晕厥。 A case of recurrent ventricular tachycardia (VT) recurrent, patients with cardiac syncope, ECG, echocardiography, X-ray cardiac imaging prompted the heart to expand. Myocardial tomography showed irreversible, segmental, spot-like thin sulfur area. Cardiac electrophysiological examination showed ventricular late potentials, ventricular program stimulation can induce persistent clinical VT. Diagnosis of dilated cardiomyopathy, VT. On April 13, 1991 placement of automatic cardioverter defibrillators, automatic defibrillation 4 times 3 months after surgery, effectively preventing syncope.
