目的探讨飞行员左室假腱索的彩色多普勒超声心动图诊断及其临床意义.方法对我院近8年来进行彩色多普勒超声心动图检查的934例男性飞行员资料进行分析,按是否存在左室假腱索对飞行员进行分组,比较两组室性早搏、T波或ST-T改变的检出率及年龄.结果 934例飞行员发现有左室假腱索98例,检出率10.49%,无假腱索者836例(占89.51%).左室假腱索组与无假腱索组飞行员所出现的室性早搏阳性率和T波或ST-T改变阳性率组间比较,差异有统计学意义(x2=97.71、70.16,P＜0.01),两组年龄比较无显著差异(t=1.479,P＞0.05).结论除外器质性心脏病,飞行员左室假腱索与临床出现的室性早搏和T波或ST-T改变有一定的关联性,左室假腱索的检出对飞行员的医学健康鉴定有一定的诊断价值和临床意义.

Objective To study the clinical significance of diagnosing pilot's left ventricular false tendons (LVFT) by color Doppler echocardiography.Methods The case history of 934 pilots who were examined by color Doppler echocardiography in recent 8 years was reviewed.Pilots were grouped by judging if the LVFT was diagnosed.The detection rate of premature ventricular contraction and the change of T wave or S-T, as well as age were compared between LVFT group and healthy group.Results There were 98 cases of LVFT picked out of 934 pilots; the detection rate was 10.49%.Masculine of premature ventricular contraction and the change of T wave or S-T in LVFT group showed significant difference (x2=97.71 and 70.16, P＜0.01) but for age (t=1.479, P＞0.05).Conclusions LVFT shows certain relationship with premature ventricular contraction and the change of T wave or S-T except the reason of organic heart disease.Even LEFT taken as a kind of normal anatomical variation but it has the possibility of evoking premature ventricular contraction after all.Caring LVFT is suggested in medical identification of pilot.
