目前临床常用的抗心律失常药物存在一些不足,除部分药物疗效不够好外,药物的不良反应,尤其是致心律失常效应,对心肌及心脏传导系统的抑制作用等明显限制了临床使用[1]。而步长稳心颗粒的安全性较好,对血常规、肝脏功能、肾脏功能、血脂及血糖无明显影响,耐受性较强,未见明显不良反应,也未发现该药有致心律失常作用,值得临床推广应用。 At present, there are some shortcomings in antiarrhythmic drugs commonly used in clinical practice. In addition to the curative effect of some drugs is not good enough, adverse drug reactions, especially arrhythmogenic effects, and inhibition of cardiac and cardiac conduction systems significantly limit the clinical use [1] . However, the step-stabilizing granule is safe and has no obvious effect on blood routine, liver function, renal function, blood lipid and blood sugar, is well tolerated, has no obvious adverse reaction, and has not been found to have induced arrhythmia ,Worthy of clinical application.
