J波是指QRS波结束和ST段起点(J点)抬高>0.1m V,时程≥20ms,向上圆顶样或驼峰样的偏离基线的波,是整体心室肌除极结束和复极开始的一个标志点。为纪念20世纪50年代初Osborn对J波开创性的观察和研究,J波也称为Osborn波。J波综合征的概念是2004年以来逐渐形成的。凡是心电图有特征性J波,临床伴有室速和心脏猝死倾向,合并或不合并器质性心脏病者,通称为J波综合征。一.J波综合征的分型自1996年多位学者研究J波的发生机制,证明
J wave refers to the end of the QRS wave and ST segment starting point (J point) elevation> 0.1m V, duration of ≥ 20ms, up dome-like or hump-like deviation from the baseline wave is the end of the overall ventricular remodeling and repolarization A mark of the beginning. To commemorate Osborn’s pioneering observation and study of J-wave in the early 1950s, J-wave is also known as Osborn wave. The concept of J wave syndrome has evolved since 2004. All ECG has a characteristic J wave, clinical with VT and sudden cardiac death tendency, with or without organic heart disease, commonly known as J wave syndrome. I. J wave syndrome classification Since 1996, many scholars study the mechanism of J wave to prove
