目的探讨动态心电图在不明原因晕厥中的诊断意义。方法选择我院诊断为晕厥患者共350例,对本组350例患者均行动态心电图监测,记录24h动态心电图监测情况。根据24h监测期间是否有晕厥发作,把350例患者分为两组,有晕厥发作为晕厥组,共65例,无晕厥发作为无晕厥发作组,共285例。结果本组350例患者中,在动态心电图监测过程中,有126例患者出现1种或者1种以上的严重心律失常,其中不包括单纯性室性早搏患者,发生严重心律失常患者所占比例为36.0%。晕厥组窦性停搏、窦房传导阻滞、房室传导阻滞、阵发性心房颤动或扑动、阵发性室上性心动过速、阵发性室性心动过速发生显著高于无晕厥发作组,差异有统计学意义(P<0.05)。结论不明原因晕厥发作可能与心律失常有关。采用动态心电图监测不明原因晕厥患者有助于明确和鉴别诊断。
Objective To investigate the diagnostic significance of ambulatory electrocardiogram in unexplained syncope. Methods A total of 350 cases of syncope were selected in our hospital. Holter monitoring was performed on 350 patients in this group. Holter monitoring was performed 24h. According to whether there was a syncope during the 24-hour monitoring period, 350 patients were divided into two groups, with syncope onset as a syncope group, a total of 65 cases, no episodes of syncope as no syncope group, a total of 285 cases. Results Among the 350 patients in this group, 126 patients had one or more serious arrhythmia during the dynamic electrocardiogram monitoring. Among them, excluding patients with simple ventricular premature beats, the proportion of serious arrhythmia patients was 36.0%. Syncope group sinus arrest, sinoatrial block, atrioventricular block, paroxysmal atrial fibrillation or flutter, paroxysmal supraventricular tachycardia, paroxysmal supraventricular tachycardia occurred significantly higher No syncope group, the difference was statistically significant (P <0.05). Conclusion unexplained syncope may be related to arrhythmia. The use of Holter monitoring of unexplained syncope in patients with clear and differential diagnosis.
