间歇性预激综合征动态心电图分析

Holter Analysis of Intermittent Pre-excitation Syndrome

目的探讨间歇性预激综合征的动态心电图特点和发病机制,为临床提供有价值信息。方法对近几年来我院动态心电图检查中记录到的22例间歇性预激综合征患者进行回顾性分析。结果间歇性预激综合征发生率为21.9%,其中12例(54.5%)呈频率依赖性发作;7例(31.8%)呈非频率依赖性发作;5例(22.7%)夜间发作较显著。8例(36.4%)伴有阵发性室上性心动过速(均在白天发作),1例(4.5%)伴心房纤颤。9例(40.9%)常规心电图未见典型预激图形表现。结论本研究间歇性预激综合征主要表现为频率依赖性、非频率依赖性和夜间发作明显等几种类型;并发的心律失常主要为前向性房室折返性心动过速和心房纤颤;常规心电图检出率较低,推荐常规使用动态心电图检查,以提高检出率。

Objective To summarize the pathogenesis of intermittent preexcition syndrome which was the advantage of holter and serve for clinical.Methods 22 patients with intermittent pre-excitation syndrome were restropectivly analyzed.Results The incidence rate of intermittent pre-excitation syndrome is 21.9%.12 cases（54.5%） attacked on frequently while 7 cases（31.8%） were not;5 cases（22.7%）were obviously in the nighttime;8 cases（36.4%）with paroxysmal supraventricular tachycardia all in day;1 case（4.5%） accompanied by atrial fibrillation;9 cases（40.9%） of ECG were normal.Conclusion Holter can improve the detection rate of intermittent pre-excitation syndrome while ECG is low.In the passage intermittent pre-excitation syndrome is analyzed in terms of attacked on frequently or not,obviously in the nighttime and so on;Often concurrent with atrial fibrillation and prior to sexual atrioventricular reentrant tachycardia.
