我院自1985年5月～1987年3月应用经食道心房调搏对22例有阵发性室上性,心动过速(PSVT)史者进行电生理检查,发现间歇性预激综合征2例,现报告如下。例1 女,27岁,有PSVT史半年,未发现器质性心脏病。调搏前ECG无预激综合征(WPW)表现,示窦性心律107次/mim。当调搏S_1S_1为500ms时,QRS交替呈现正常与预激图形.S_1S_1为
Our hospital from May 1985 to March 1987 application of transesophageal atrial pacing on 22 cases of paroxysmal supraventricular tachycardia (PSVT) history of electrophysiological examination and found that intermittent WPW syndrome 2 For example, the report is as follows. Example 1 Female, 27 years old, with PSVT history of six months, no organic heart disease found. Pre-pacing ECG without WPW performance, showing sinus rhythm 107 times / mim. When pacing S_1S_1 is 500ms, QRS alternates between normal and pre-excitation patterns. S_1S_1 is
