本文采用 ACG、PCG、ECG 同步记录方法,对85例健康飞行人员心房收缩时间间期(ASTI)。参考常值进行了测定分析。并对各项测定指标与年龄和心率的关系分别做了分析。结果推出健康飞行人员 ASTI 的参考常值。还发现在飞行人员的年龄和心率范围内 ASTI 常值受年龄及心率影响不大,可不予校正。还提示 APEP/AET 是一项测定和评价心脏舒张功能的敏感指标。因为 ASTI 是反映心舒功能的早期指标之一,所以建议把测定 ASTI 列入评定飞行人员心舒功能指标,以便提高检出率。
In this paper, ACG, PCG, ECG synchronized recording method, 85 healthy flight atrial systolic time interval (ASTI). The reference value was measured and analyzed. And the relationship between the determination of indicators and age and heart rate were analyzed separately. Results The reference value of ASTI for healthy pilots was introduced. It was also found that ASTI values, which are not significantly affected by age and heart rate, can be left uncorrected within the age and heart rate range of pilots. It also suggested that APEP / AET is a sensitive measure of diastolic function. Because ASTI is one of the early indicators of cardiac function, it is recommended that ASTI be included in the assessment of heart function parameters of pilots in order to improve the detection rate.
