患者男性,31岁,患预激综合征(A 型)伴反复发作室上性快速性心律失常。图 A:房颤伴快速性室率(240～260次/分),QRS 波示为通过左侧旁道传导独有的图形。图 B:为第2天纪录,业已转为窦性心律,第1、2、4、5和7心搏的 P-R 间期0.12秒,且有预激渡,故是1例预激综合征。这些 QRS 波为预激综合征本身常见的室性融 Male patient, 31 years old, with pre-excitation syndrome (A type) with recurrent supraventricular tachyarrhythmia. Figure A: Atrial fibrillation with rapid ventricular rate (240 ~ 260 beats / min), QRS waveforms through the left side of the vaginal conduction unique graphics. Figure B: record for the second day, has been converted to sinus rhythm, 1,2,4,5 and 7 heart rate P-R interval of 0.12 seconds, and pre-excitation, it is a pre-excitation syndrome. These QRS waves are common to the WPW syndrome itself
