摘　　要：目的探讨单中心心血管内科门诊流出道室性早搏（OT—PVC）检出率，分析其基本特征。方法对在2013年1月1日至2013年6月30日期间就诊于本中心心血管内科门诊患者的心电图进行检测，并就其中OT—PVC患者情况及其心电图资料进行分析。结果共接诊患者5545例，检出OT-PVC160例，占2．89％，其中男性62例（38．75％），女性98例（61．25％）。（〉50～60）岁年龄段患者38例，占3．53％，高于其他年龄段。71例OT-PVC患者（44．38％）合并其他类型的心电图异常，依次为T波倒置、ST压低、心房颤动、左房负荷异常及房性早搏。分析发现这71例患者与未合并上述心电图异常的89例OT-PVC患者相比平均年龄偏大[（62．2±12．0）岁vs（46．4±16．3）岁，P〈0．05]。结论单中心心血管病门诊就诊人群心电图OT—PVC检出率为2．89％，其中（〉150～60）岁人群的OT—PVC检出率高于其他年龄段。随着年龄的增长，OT-PVC患者更易合并其他类型的心电图异常。Objective To investigate the occurrence and characteristics of outpatients with premature ventricular contractions originating from ventricular outflow tract （OT-PVC） detected by electrocardiogram （ECG） in a single center. Methods We collected and analyzed the general characteristics and ECG of outpatients who were diagnosed as OT-PVC from January 01, 2013 to June 30, 2013 in the department of cardiology of the First Affiliated Hospital of Nanjing Medical University. Results ECG of 5545 outpatients were obtained in six months, in whom there were 160 patients （2.89%） with OT-PVC, including 62 males（38.75% ） and 98 females（61.25% ）. Thirty eight patients with OT-PVC （3.53%） were between 50 and 60 years old and its ratio was higher than the other OT-PVC patients who were less than 50 and more than 60 years old. The ECG in 71 patients （44.38%） with OT-PVC showed the following abnormalities, including T-wave inversion, ST-segment depression, atrial fibrillation, over-loading of left atrium and premature atrial complex. The average age of patients with ECG abnormalities was elder than that of patients without ECG abnormality [ （62.18±12.03） vs （46. 37± 16.30） years old, P〈0.05 ]. Conclusion The detection ratio of OT-PVC in outpatients is 2.89% and its ratio is higher in outpatients between 50 and 60 years old. ECG abnormalities are common in older patients with OT-PVC.
