摘要
目的：通过深呼吸心电图试验，探讨观察心脏自主神经功能的无创性方法。方法：１０９ 名健康成人，描记１２ 导联心电图，在Ⅱ导联上分别描记平卧平静呼吸、深呼吸时心电图。分析Ｐ－Ｒ间期、Ｐ－Ｐ间期的变化。结果：深吸气时Ｐ－Ｒ间期、Ｐ－Ｐ间期均较平静呼吸缩短，深呼气时Ｐ－Ｒ间期、Ｐ－Ｐ间期均较平静呼吸时延长，均Ｐ＜ ０．０１。结论：深呼吸时Ｐ－Ｒ间期。
Objective:To approach a safety method for evaluating cardiovascular autonomic function in electrocardiogram test during deep respiration.Methods:109 healthy adults entered the study,the electrocardiogram of 12 leads was recorded,then the electrocardiongram of Ⅱ lead was recorded on normal respiration in the horizontal position and during deep respiration.The variation of P R interval and P P interval in all persons was analysed.Results: The P R interval and P P interval with all people was shorten during deep inhalation than those on normal respiration,the P R interval and P P interval with all people was prolonged during deep exhalation than those on normal respiration.There was statistical significant difference between the two states for the above results.Conclusion: The study suggested that the change of P R interval and P P interval during deep respiration be a powerful tool for evaluating cardiovascular autonomic function.
