摘　　要：目的探讨动态心电图(Holter)在不明原因晕厥诊断中的应用价值。方法对146例不明原因的晕厥患者进行24小时Holter检查。全部患者经病史、体检、常规心电图和体位性低血压试验等均未发现晕厥的直接原因。结果146例患者经Holter检查,55例(37.67%)出现心律失常,25例(17.12%)出现晕厥发作,22例(15.06%)晕厥发作与心律失常有关。尤其与心电图RR间期有一定的相关性。25例晕厥患者中,RR间期≥3.0秒者共57次,其中31次发生晕厥;而RR间期<3.0秒者256次,无1例发生晕厥(P<0.01)。结论一些不明原因晕厥的发作与心律失常有关。Holter检查对不明原因晕厥的病因诊断仍然是一种有价值的工具。To evaluate the diagnostic value of 24-hour electrocardigraphic monitoring （Holter） in the patients with unexplained syncope. Methods Holter examination was used in 146 patients with unexplained syncope,who with no direct clue for syncope with a careful inquiring,physical and 12-lead ECG examination, and the test of postural hypotension. Results Arrhythmias occurred in 55 cases （37.67%） and syncope in 25 cases （ 17.12% ） out of 146 patients during Hoher examination. Results showed that syncope attack occurred with arrhythmias appearance in 22 cases（ 15.06% ）and there was some correlation between syncope attack and RR interval. 57 times of RR interval ≥ 3.0 seconds happened in 25 the syncope patients and 31 times of RR interval ≥ 3.0 seconds happened just with the attack of syncope,while no syncope attack occurred in 256 times of RR interval 〈 3.0 seconds （ P 〈 0.01 ）. Conclusions The occurrence of unexplained syncope attack is related with arrhythmia and Hoher examination is useful to the diagnosis of unexplained syncope.
