本研究旨在确定滴注肾上腺素能否抵消维拉帕米的电生理效应,及其抵消维拉帕米对阵发性室上性心动过速(PSVT)的预防作用能否预报维拉帕米长期治疗期间应激性PSVT 复发与否。方法经电生理研究的17例反复发作PSVT 的病人(临床上曾用维拉帕米无效或不能耐受者已除外),男7例,女10例,年龄45±17岁。1例有心肌梗塞史。其余16例无器质性心脏病。停服所有抗心律失常药物至少5个半衰期。8例在未服维拉帕米的情况下作基础电生理研究并测定25ng/kg/min
The purpose of this study was to determine if adrenaline infusion can counteract the electrophysiological effect of verapamil and whether it can prevent the effect of verapamil on the prevention of paroxysmal supraventricular tachycardia (PSVT) Long-term treatment of stress PSVT recurrence or not. Methods Seventeen patients with recurrent PSVT who had been treated with electrophysiological studies (except those who had been inactive or unable to tolerate verapamil in clinical practice) had 7 males and 10 females, aged 45 ± 17 years. One patient had a history of myocardial infarction. The remaining 16 cases without organic heart disease. Stop taking at least 5 half-lives of all anti-arrhythmic drugs. Eight patients underwent veterinary electrophysiological studies without taking verapamil and measured 25 ng / kg / min
