持续的室性心律失常是心脏插管检查的重要并发症,往往发生在造影剂注入冠(状动)脉之后(一般认为发生率可达2%),至于自主神经反射所起的作用迄今未明。尽管常常在冠脉造影术前预防性使用毒蕈碱样受体阻断剂阿托品,以减少窦性心动过缓和血管迷走反应,然而阿托品预防室性心律失常的效果,意见截然不同。本试验按照病例-对照的方式进行。在 Continuous ventricular arrhythmia is an important complication of cardiac catheterization, often occurs after the contrast agent is injected into the coronary artery (generally considered to be up to 2%), and the role of autonomic reflex so far unknown . Although prophylactic use of the muscarinic receptor blocker atropine prior to coronary angiography has been shown to reduce sinus bradycardia and vasovagal reactions, the effect of atropine on preventing ventricular arrhythmias is quite different. The trial was conducted in a case-control manner. in
