摘要
本文用英国Ｏｘｆｏｒｄ公司的ＭｅｄｉｌｏｇＥｘｃｅｌ长程心电图分析系统探讨了１６名飞行员在急性热应激和飞行应激这两天４８ｈ心电的动态变化。结果发现，热应激心率的最高值在第二次劳动时，而飞行应激心率的最高值在飞行前５ｍｉｎ，特别是年轻飞行员其心率增高更甚，在这期间大多飞行员在热应激和飞行应激这两天大多出现了房性、室性早搏，提前出现Ｐ－ＱＲＳ波和代偿不全，而这些异常心律大多在热应激劳动和飞行起飞前３０ｍｉｎ出现。提示飞行时，其负荷最大值在飞行前的３０ｍｉｎ，并为预防飞行事故等提供了科学依据。
he dynamic changes of electrocardiogram of 16pilots during acute heat stress and flight stress wasstudied with the long-distance electrocardiogram ana-lytical system of Medilog Excel made by England Ox-ford Company. Results were shown as follows. Thepeak of heart rate during acute heat stress occurred insecond labour, but that during flight stress's day oc-curred at 5 minutes prior to flight, especially, muchmore increased in young pilots, Most of the pilots suf-fered from atrial or ventricular premature beat, prece-dent occurrance of P-QRS and incomplete compensa-tion. Most of the arrhythmia occurred during workwith heat stress and 30 min before flight, These re-sults might provide certain scientific data for preven-tion of flight accidents.
