临床心脏电生理学检查(Electrophysiologic Studies简称EPS)是在记录心腔内心电图的基础上,于病人自身窦性心律或心房起搏心律时,对心房或心室进行递增起搏Incremental Pacing)或程序电刺激(Programmed Stimulation)以观察心脏电活动的变化。此项检查对于心律失常的诊断,病变的准确定位,某些心律失常的发病机理,抗心律失常的药物作用机制以及对病人进行药物、起搏或手术治疗的合理选择等都具有重要意义。
The clinical electrophysiology study (Electrophysiologic Studies referred to as EPS) is based on the recording of intracardiac electrocardiogram, in patients with sinus rhythm or atrial pacing heart rate, atrial or ventricular ventricular pacing Incremental Pacing) or procedural electrical stimulation (Programmed Stimulation) to observe changes in cardiac electrical activity. This test is important for the diagnosis of arrhythmias, the precise location of lesions, the pathogenesis of certain arrhythmias, the mechanism of action of antiarrhythmic drugs, and the rational selection of medications, pacing or surgery for patients.
