心源性晕厥51例临床分析

Cinical analysis of 51 cases of cardiac syncope

目的探讨心源性晕厥的病因构成及辅助检查技术对其诊断的意义。方法回顾性分析51例心源性晕厥患者的临床资料。结果心源性晕厥的原因:心律失常41例,占80.4%,其中缓慢型心律失常32例,快速型心律失常9例;心脏流出道阻塞8例,占15.7%;其他原因2例,占3.9%。常规心电图(ECG)、24 h动态心电图(包括长时间心电监护)(Holter)、超声心动图(UCG)等辅助检查可对大多数心源性晕厥患者作出诊断,多排螺旋X线计算机断层扫描(MSCT)可对少数患者作出诊断。结论心源性晕厥原因以心律失常为主,心脏流出道阻塞次之,其他原因占少数。ECG、Holter、UCG等对心源性晕厥诊断有重要意义,MSCT可对少数病例作出诊断。

Objective To investigate the cause of cardiac syncope and the roles of auxiliary inspection techniques in diagnosis. Methods Retrospectively analyzed clinical data of 51 cases of cardiac syncope. Results Causes of cardiac syncope： 41 cases of arrhythmia, accounting for 80.4%, of which, 32 cases were arrhythmias and 7 cases were tachyarrhythmia; 8 cases of cardiac outflow tract obstruction, accounting for 15.7%; 2 cases of other reason, accounting for 3.9%. Electrocardiography（ECG）, 24 h ambulatory electrocardiogram（including long time ECG monitoring）（Holter）, echocardiography（ultrasonic cardiogram, UCG） and other laboratory examinations could help diagnose majority of cardiac syncope patients, while multi-slice spiral computed tomography（MSCT） may be could helpful for minority cases. Conclusion The main etiology of cardiac syncope is cardiac arrhythmia, the second is cardiac outflow tract obstruction, other reasons for the minority. ECG, Holter and UCG Play a major role in the diagnosis of cardiac syncope, while MSCT makes great contribution to diagnose minority cases.
