Ethacizine hydrochloride (Ethacizin; NIK-244) 是一种抗心律不齐的化合物 (Class Ic antiarrhythmic agent)，比 Flecainidex 作用时间更持久。Ethacizine hydrochloride (Ethacizin; NIK-244) 可以抑制负责心房和 His-Purkinje 心室传导的电流的去极化。
Ethacizine hydrochloride (Ethacizin; NIK-244) is a longer-lasting Class Ic antiarrhythmic agent than Flecainide[1]. Ethacizine hydrochloride (Ethacizin; NIK-244) inhibits the depolarizing current responsible for the intraatrial and His-Purkinje-ventricular conduction[2].
NIK-244 (1-300 ug) injects directly into the SA node and PM preparations shows negative chronotropic, negative inotropic and coronary vasodilator[1].
