心电图p波形态在一定程度上可反映左、右心房的解剖学和血流动力学改变.过去在一些有关左房大小与P波形态学关系的研究中,左房值的测定主要是根据手术时的直接观察、心脏各个面上的X线分析或死后的尸检研究.超声心动图所测左房大小与心血管造影所得者有良好的相关性.本文以超声心动图测得的左房值为“标准”.对心电图中一般认为反映左房大小的几项指标予以检验.
ECG p wave morphology to a certain extent, can reflect the left and right atrium anatomy and hemodynamic changes in the past in some studies on the relationship between left atrial size and P wave morphology, the determination of left atrial value is mainly based on surgery Time direct observation, X-ray analysis of all aspects of the heart or post mortem autopsy study.Echo heart measured by left atrial size and cardiovascular angiography have a good correlation.The echocardiography measured left atrial The value is “Standard.” Several indicators of the size of the left atrium that are generally considered to be on the ECG are examined.
