29例心源性晕厥患者动态心电图分析

Ambulatory Electrocardiography analysis of 29 patients with cardiac syncope

目的研究心源性晕厥患者的心律失常发生情况与高危心电图的具体表现。方法对29例疑为心源性晕厥的患者进行24 h动态心电图监测。结果 29例患者均发生了较严重的心律失常,晕厥15例,R-R间期小于3.0 s者无晕厥表现,R-R间期大于3.0 s者出现晕厥表现。结论心律失常尤其是慢性心律失常是造成心源性晕厥的主要原因,一般具有器质性心脏病的患者进行动态心电图检查,可以获得可靠的病因,并进行针对性的治疗。

Objective To study the ocurrence of arrhythmia of patients with cardiac syncope and specific high-risk electrocardiographic representations. Methods Twenty-nine patients suspected with cardiac syncope underwent 24 h ambulatory electrocardiography inspection. Results Serious arrhythmias occurred in the selected 29 cases, among whom there were 15 cases with cardiac syncope. Cardiac syncope failed to represent itself on patients whose R-R interval 〈 3.0 s while it occurred in patients whose R-R interval 〉 3.0 s. Conclusion Arrhythmia especially chronic arrhythmia is the main cause of cardiac syncope. Generally, for patients with organic heart disease, ambulatory electrocardiography inspection could help in finding reliable pathogeny and choosing corresponding treatment.
