Changes of Heart Functions in the Minesweeper Crew after the Synchronous Magnetic Minesweeping Operations

目的 :观察扫雷艇同步扫雷通磁作业前后艇员心功能的变化。方法 :对 5 0名参加同步扫雷实验的艇员在实验前和实验后进行心功能测试。结果 :实验后艇员EVI明显降低 ,VET明显缩短 ,TFI、HR、SV、CO、CI无明显变化。结论

Objective: To observe changes of heart functions in the minesweeper crew after the synchronous magnetic minesweeping operations. Methods: Heart functions of 50 minesweeper crewmembers were measured before and after the synchronous magnetic minesweeping operations . Results: After being exposed to the magnetic field during the minesweeping operations , the EVI value of the experimental crewmembers decreased markedly, and the VET shortened significantly . No significant changes were shown in TFI, HR, SV, CO and CI . Conclusion: The heart functions of the minesweeper crew were affected to some extent by the synchronous magnetic minesweeping operations.
