近年来将心电向量图应用于临床诊断方面,越来越引起了人们的注意,特别自Frank校正导联体系被广泛应用以来,对诊断心肌梗塞、心室肥厚和心室内传导阻滞等方面已积累了大量资料,并发现比心电图有较为优越之处。最初主要是对心室除极过程(QRS环)进行研究,对心室复极过程(ST同量和T环)的研究则较少。冠心病是一种缺血性心脏
In recent years, the application of electrocardiogram to clinical diagnosis has drawn more and more attention. Especially since Frank’s corrected lead system has been widely used, it has been widely used in the diagnosis of myocardial infarction, ventricular hypertrophy and intraventricular conduction block Accumulated a large amount of information and found that there are more advantages than the ECG. Initially mainly on the ventricular depolarization process (QRS ring) to study the ventricular repolarization process (ST same amount and T-ring) are less studied.
