心律失常分类极其繁多,大多数不需要治疗,但有的患者即使没有自觉症状,也有发展为致命的心室颤动的危险。现就需要治疗的心律失常及其发生机制和有效治疗药物及其作用机制简述如下: 一、需要药物治疗的心律失常1.直接致死性的心律失常:如完全性房室传异阻滞,一旦引起心室颤动,用药物治疗就来不及了。唯一抢救的办法就是早期发现,采用电除颤方法治疗,因此预防性的药物治疗就是个重要问题。2.可诱发致死的心律失常:一旦发现必须立即进行药物治疗。例如见有R on T现象的室性早搏、急性心肌梗塞合并室性早搏、室性心动过速、多源多发性室性早搏等。
Arrhythmia classification is extremely diverse, most do not need treatment, but some patients even without symptoms, but also the risk of developing a lethal ventricular fibrillation. Now need to be treated arrhythmia and its mechanism and effective treatment of drugs and their mechanism of action is as follows: First, the need for drug treatment arrhythmia 1. Direct lethal arrhythmia: such as complete atrioventricular block, Once caused by ventricular fibrillation, with the drug treatment is too late. The only way to rescue is early detection, the use of defibrillation treatment, so preventive drug treatment is an important issue. 2. Induced lethal arrhythmia: once found must be immediately drug treatment. For example, see the phenomenon of R on T premature ventricular contractions, acute myocardial infarction complicated by premature ventricular contractions, ventricular tachycardia, multiple sources of premature ventricular contractions and more.
