目的明确是否各处预激都有QRS终末波极性改变。方法收集各种比例(2∶1～4∶3)的间歇性预激综合征共11例。按射频导管消融成功的靶点定位,分析QRS终末波的极性。结果预激使QRS终末波极性逆转10例。至少2个导联逆转的有8例,最多1例达5个导联。前8例涵盖了左心室前壁和侧壁,右心室前壁、侧壁、后壁、前间隔和后间隔。结论心室去极化过程中,预激始终存在是引起预激综合征QRS终末波极性改变的原因。这种改变并不局限于少数区域。
The purpose is to determine whether there is QRS terminal wave polarity changes everywhere. Methods A total of 11 patients with intermittent WPW syndrome of various proportions (2: 1 ~ 4: 3) were collected. According to the successful localization of RF catheter ablation, the polarity of QRS terminal wave was analyzed. Results Pre-excitation reversed QRS terminal wave polarity in 10 cases. At least 2 lead reversal in 8 cases, up to 1 case up to 5 leads. The first eight cases covered the anterior and posterior wall of the left ventricle, the anterior wall of the right ventricle, the lateral wall, the posterior wall, the anterior and posterior septum. Conclusions During the process of ventricular depolarization, the existence of prefetch is always the cause of the polarity change of QRS terminal wave in WPW syndrome. This change is not limited to a few areas.
