心律失常在临床上很常见。对心律失常的诊断和治疗正确与否,对患者的预后有着一定的关系,有时甚至起着决定性的作用。应用治疗心律失常药物之前宜明确诊断,否则可带来危害,如本来是心房扑动,误诊为室性心动过速而应用利多卡因治疗,因本品对心房扑动病人常能加速房室传导,增加心室率,从而可发生具有心率将近300次/分的1:1房室传导,在血液动力学上能产生灾难性后果。即使明确了诊断,也不是所有心律失常都需用抗心律失常药。此类药物主要用于下列心律失常:1.产生血液动力学循环不
Arrhythmias are clinically common. Right arrhythmia diagnosis and treatment is correct or not, the prognosis of patients has a certain relationship, and sometimes even play a decisive role. Application of the treatment of arrhythmia drugs should be a clear diagnosis, otherwise it may bring harm, such as atrial flutter was originally misdiagnosed as ventricular tachycardia and the application of lidocaine treatment, because of the goods on the atrial flutter patients can often accelerate the atrioventricular Conduction, increase ventricular rate, which can occur with a heart rate of nearly 300 beats / min 1: 1 AV conduction, can produce haemodynamically disastrous consequences. Even if the diagnosis is clear, not all arrhythmias require anti-arrhythmic drugs. Such drugs are mainly used for the following arrhythmias: 1. Hemodynamic cycles are not produced
