本文回顾分析的对象为60±10岁的连续62例慢性冠心病患者,经Holter监测证实均有非持续性室性心动过速(NSVT)。除3例外,均有心肌梗塞史,此后平均43(2～180)个月进行电生理测试。16例形成左室壁瘤。电生理测试前停用抗心律失常药物至少48小时。经右心电极导管程控刺激右室(期外刺激至多3个)。28例(45％)诱发持续性窒性心动过速(SVT),给予抗心律失常药物后复查:12例药物有效即仅能诱发心搏≤10次的室性心动过速(VT),另12例则否。15例(24％)诱发NSVT,仅11例伴有晕厥或心悸者给药后复查:7例药物有效即未能诱发VT,另4例则否。19例(31％)未能诱发VT。共34例未能诱发SVT。
This retrospective analysis of the target for 60 ± 10-year-old patients with consecutive 62 cases of coronary heart disease, Holter monitoring confirmed non-sustained ventricular tachycardia (NSVT). All but 3 patients had a history of myocardial infarction and were followed by an average of 43 (2 to 180) months for electrophysiological testing. 16 cases of left ventricular aneurysm formation. Anti-arrhythmic drugs are discontinued for at least 48 hours prior to electrophysiological testing. Right ventricular lead by the right to stimulate the right ventricle (extra-period stimulation up to 3). Twenty-eight patients (45%) had sustained supratentorial tachycardia (SVT) after anti-arrhythmic drug treatment. The 12 drug-effective patients were only able to induce ventricular tachycardia (VT) 12 cases are not. Fifteen patients (24%) developed NSVT, and only 11 patients had syncope or palpitations. The patients were followed up after administration. Seven patients failed to induce VT with effective drugs, and the other four patients did not. Nineteen (31%) failed to induce VT. A total of 34 cases failed to induce SVT.
