目的 了解飞行人员期前收缩的心电图特点 ,为其健康鉴定提供参考。 方法 分析 1995～ 2 0 0 3年度健康疗养飞行人员期前收缩心电图和临床体检资料。 结果 飞行人员期前收缩阳性率为 0 .8% ,期前收缩均呈单源性 ,并以室性多见(79.3% ) ,6 3.8%的期前收缩可找到明确的诱发因素 ,常见为旅途疲劳、吸烟、休息不佳、饮用兴奋性饮料等 ,去除这些诱发因素后期前收缩可自行消失。 2 7.6 %的期前收缩后伴有轻度T波改变 ,但无器质性心脏病证据。 结论 飞行人员期前收缩多数为功能性 ,无明确的航空医学意义。
Objective To understand the characteristics of electrocardiogram (ECG) of premature contractions of pilots and provide references for their health identification. Methods The data of pre-contracted ECG and clinical examination of health-care flight personnel from 1995 to 2003 were analyzed. Results The positive rate of premature contractions in pilots was 0.8%, and the premature contractions were all single source. The clear predisposing factors were found in premature contractions of ventricular (79.3%) and premature contractions Travel fatigue, smoking, poor rest, drink excitatory drinks, remove these predisposing factors can disappear before the end of contraction. 2 7.6% of pre-term contractions accompanied by mild T wave changes, but no organic heart disease evidence. Conclusions The majority of pilots’ previous contraction are functional and have no definite aviation medical significance.
