近年来国外关于预激综合征的研究较多,可归纳为下列三方面:一、心电图、心向量与超声心动图的检查(一)心电图的表现:由于预激综合征的解剖学基础及功能变化极为复杂,放心电图的表现亦变化多端。根据解剖学的分类,可分三类:(1)经过附加房——室肌束(Kent束)的预激,心电图表现为 P—R,Delta 波(△波)及宽 QRS 波;此型又称典型预激或 WPW 综合征,最常见;(2)经过房室结内旁道束(James 纤维)的预激,心电图表现为短 P-R
In recent years, there are many foreign studies on Wolff-Parkinson-White syndrome, which can be summarized as follows: First, ECG, cardiac vector and echocardiography (A) ECG performance: The changes are extremely complex, and the performance of the electrocardiogram is also varied. According to the classification of anatomy, there are three types of pre-excitation: (1) P-R, Delta wave (△ wave) and wide QRS wave through the pre-excitation of additional room-Kent beam; Also known as typical WPW or WPW syndrome, the most common; (2) pre-excitation through the atrioventricular node (James fiber), ECG showed short PR
