目的探讨对不明原因晕厥患者采用食道电生理与动态心电图检查的临床诊断价值。方法选取26例不明原因晕厥患者,对其进行脑电图、脑血流图、心脏超声、查体等检查,排除短暂脑缺血发作、癫痫等疾病。对其采用食道电生理与动态心电图检查,对食道电生理与动态心电图检查结果进行分析。结果 26例不明原因晕厥患者中有14例(53.85%)患者经食道电生理检查检出为心源性晕厥,余12例患者考虑为其他原因引起的晕厥。有11例(42.31%)患者经动态心电图检查检出为心源性晕厥。动态心电图无异常的15例患者中经食道电生理检查有1例患者发现异常。结论食道电生理检查和动态心电图检查可较准确的检出不明原因晕厥患者的病因,且检出率较高,是心源性晕厥有效诊断手段之一。 Objective To investigate the value of esophageal electrophysiology and ambulatory electrocardiogram in patients with unexplained syncope. Methods Twenty-six patients with unexplained syncope were selected and examined by EEG, cerebral blood flow, echocardiography and physical examination to exclude short-term ischemic attack and epilepsy. The use of esophageal electrophysiology and Holter examination of esophageal electrophysiological and dynamic electrocardiogram examination results were analyzed. Results Fourteen (53.85%) of 26 patients with unexplained syncope were found to have cardiogenic syncope by esophageal electrophysiological examination, and the remaining 12 patients were considered for other causes of syncope. Eleven patients (42.31%) were found to have cardiogenic syncope by ambulatory electrocardiogram. One patient with abnormal electrocardiogram in 15 cases of esophageal electrophysiological examination found abnormalities. Conclusion Esophageal electrophysiological examination and dynamic electrocardiogram can detect the etiology of patients with unexplained syncope more accurately, and the detection rate is higher, which is one of the effective diagnostic methods of cardiogenic syncope.
