心脏电生理检查应用临床以来日益广泛,目前除用于心律失常,预激综合征的诊断与手术治疗、药物效果的评价,还用于冠心病的诊断等。临床电生理检查一般分为创伤性和非创伤性两种。前者通过静脉插入多根电极导管,在X线下进行,技术要求较高,有一定局限性,国外大多采用这种方法。后者经食道插入一根多电极导管在心房水平附近进行调搏并记录体表心电图,对分别测量窦房结、房室结的功能,不应期测定,预激综合征和冠心病的诊断以及诱发和终止室上性心动过速等都有帮助。国内大多采用这种方法。最近我们也开展这项工作,现将临床电生理检查方法介绍如下。
Cardiac electrophysiological examination since the clinical application has become increasingly widespread, in addition to currently used for arrhythmia, pre-excitation syndrome diagnosis and surgical treatment, the evaluation of drug effects, but also for the diagnosis of coronary heart disease. Clinical electrophysiology is generally divided into traumatic and non-invasive two. The former is inserted through a vein multiple electrode catheter, carried out under the X-ray, high technical requirements, there are some limitations, most of this method is used abroad. The latter through the esophagus inserted into a multi-electrode catheter in the vicinity of the atrial pacing and recording the surface ECG, respectively, the measurement of sinoatrial node, atrioventricular node function, refractory period determination, Wolff-Parkinson’s syndrome and coronary heart disease diagnosis As well as induction and termination of supraventricular tachycardia, etc. are helpful. Most domestic use of this method. Recently, we also carry out this work, now the clinical electrophysiological methods are described below.
