目的探讨电生理检查对不明原因晕厥患者的诊断价值。方法对75例经无创性检查未能明确原因的晕厥患者进行电生理检查,并对其电生理结果及其并发症进行统计分析。结果电生理检查总的阳性率为40%,随年龄的增加,其电生理检查的阳性率亦增加,其中60岁以上患者因冠心病者比例较高其电生理检查阳性率高达50%。结论电生理检查对不明原因晕厥患者,尤其是老年伴器质性心脏病患者有一定诊断价值。
Objective To investigate the diagnostic value of electrophysiological examination in patients with unexplained syncope. Methods Seventy-five patients with syncope who had no definite cause of noninvasive examination were analyzed by electrophysiological method and their electrophysiological results and complications were statistically analyzed. Results The positive rate of electrophysiological examination was 40%. With the increase of age, the positive rate of electrophysiological examination was also increased. The positive rate of electrophysiological examination in patients over 60 years old was as high as 50% due to the higher proportion of patients with coronary heart disease. Conclusion Electrophysiological examination of patients with unexplained syncope, especially elderly patients with organic heart disease have a certain diagnostic value.
