摘　　要：目的探讨动态心电图联合超声心动图评估预激综合征患者心脏功能的价值。方法入选2012年1月至2019年6月期间在首都医科大学附属北京天坛医院行动态心电图和超声心动图检查的预激综合征患者87例作为研究组。选取同时期在本院行超声心动图和动态心电图检查、且无明确心脏疾病者87例作为对照组。2组研究对象都进行动态心电图联合超声心动图检查,比较2组各项指标的异同。采用SPSS 21.0软件进行统计分析。2组间数据比较采用t检验或Mann-Whitney U检验。结果研究组患者肺动脉主干内径[(20.77±2.61)和(19.94±2.19)mm]、左房横径[(32.44±4.86)和(30.93±3.21)mm]、室间隔厚度[(10.1±2.37)和(9.26±1.33)mm]、左室舒张末内径[(44.55±4.33)和(42.91±4.07)mm]、主动脉流速[(130.91±34.60)和(118.95±21.42)cm/s]均显著大于对照组(P<0.05);研究组左室射血分数[(64.93±5.93)%和(66.95±5.04)%]显著小于对照组(P<0.05)。研究组和对照组动态心电图心率变异性的指标之间差异无统计学意义。结论超声心动图对于预激综合征相关的心脏形态改变的监测具有参考意义,动态心电图的心率变异性指标对于预激综合征的诊断意义尚需进一步研究。Objective To explore the roles of dynamic electrocardiography(DCG)combined with echocardiography in the evaluation of cardiac function in patients with preexcitation syndrome.Methods A total of 87 patients with preexcitation syndrome who received Holter monitoring and echocardiography from January 2012 to June 2019 in our hospital were enrolled in this study and served as the study group.And another 87 individuals without identified heart disease who received the two examinations at the same period were subjected to normal control group.The differences in the indices of Holter and echocardiography were compared between the two groups.SPSS statistics 21.0 was used for statistical analysis.Intergroup data comparison was performed using t text or Mann-whitney U test.Results The pulmonary artery diameter[(20.77±2.61)vs(19.94±2.19)mm],left atrial transverse diameter[(32.44±4.86)vs(30.93±3.21)mm],interventricular septal thickness[(10.1±2.37)vs(9.26±1.33)mm],left ventricular diastolic diameter[(44.55±4.33)vs(42.91±4.07)mm]and aortic velocity[(130.91±34.60)vs(118.95±21.42)cm/s]were all significantly larger(P<0.05),but left ventricular ejection fraction was obviously lower[(64.93±5.93)%vs(66.95±5.04)%,P<0.05]in the study group than the control group.There was no significant difference in the indicators of heart rate variability between the two groups.Conclusion Echocardiography can be used as a reference for the diagnosis of preexcitation syndrome related cardiac morphological changes.Further study should be performed for the diagnostic significance of the indicators of heart rate variability by DCG for preexcitation syndrome.
