用微机自动检测的方法测定了93名大学生(男50,女43)的心脏收缩时间间期(STI),并进行了STI与心率的相关回归分析。结果表明STI的多数指标女性较男性稍高,其中MST、ICT性别差异非常显著,EMT差异显著;而PEP/LVET、ICT/LVET、Qu/LVET、EML、PWTT等指标性别差异不显著。男组和女组的EMT、LVET、PEP、MST、ICT与心率有非常显著的负相关;而PEP/LVET、ICT/LVET、Qu/LVET及EML、PWTT与心率不相关。
The systolic time of heart (STI) of 93 college students (male 50, female 43) was measured by microcomputer and the correlation analysis between STI and heart rate was performed. The results showed that the majority of female STI indicators were slightly higher than those of male ones. Among them, MST and ICT had significant differences in gender and EMT, while gender differences in PEP / LVET, ICT / LVET, Qu / LVET, EML and PWTT were not significant. There was a very significant negative correlation between EMT, LVET, PEP, MST, ICT and heart rate in male and female groups, while PWTT was not related to heart rate in PEP / LVET, ICT / LVET, Qu / LVET and EML.
