心导管术是将一根心导管插入心脏各部,借以诊断心血管疾病,进行选择性心血管造影及冠状动脉造影,指示剂稀释曲线测定,记录心内心电图,心音图,希氏束心电图,监护危重病人的病情变化,研究心脏血液循环动力学以及进行心内膜导管电极起搏等的一种方法。国外自 Forsmann 于一九二九年首先用心导管进行右心导管插管以后,引起了临床家对此检查的广泛重视,至一九四五年右心导管检查方法已日趋完善。一九五○年有人由尺动脉将心导管插入左心室进行左心导管检查。此后不同作者采用不同的方法进行了左心导管检查,
Cardiac Catheterization Cardiac catheterization is the insertion of a cardiac catheterization into the heart to diagnose cardiovascular disease, selective cardiovascular angiography and coronary angiography, determination of indicator dilution curves, recording of intracardiac electrocardiogram, phonocardiogram, His bundle beam electrocardiogram, monitoring Critically ill patients with changes in the condition, study of cardiac blood circulation dynamics and endocardial catheter electrode pacing and so on. After Forsmann first performed cardiac catheterization right-heart catheterization abroad in 1929, clinicians have drawn extensive attention to this examination. By 1945, right-heart catheterization methods have been perfected. In 1950, a cardiac catheter was inserted into the left ventricle from the ulnar artery for left heart catheterization. Since then different authors used different methods of left heart catheterization,
