| 摘 要： | 目的探讨气功调息在不同呼吸方式下对心率变异(HRV)的影响。方法对36例气功练功者用标准指导语控制5次／min,10次／min,20次／min均匀呼吸调节指导调息,同步用动态Holter记录心电和呼吸波型。结果在5次／min、10次／min、20次／min均匀呼吸调节调息下,HRV分别在0．05—0．12Hz、0．15—0．20Hz、0．23—0．30Hz出现调息峰。同时呼吸的周期变化和心率的R—R间期变化完全同步。结论均匀呼吸的调息频率改变不仅影响HRV的高频段,而且还会影响HRV的低频段。因此,均匀呼吸调节引起的HRV变化可能不一定完全反映心血管自主神经平衡调节的变化。

| Abstract: | Objective To explore the effects of different respiration modalities of"Qigong Tiaoxi"on heart rate variability (HRV).Method 36 Qigong practitioners were tested by uniform respiration at 5/min,10/min and 20/min, recording electrocardiogram (ECG) and respiratory wave. Results The peaks of"Tiaoxi" were showed in 0.05-0.12Hz, 0.15-0.20Hz and 0.23-0.30Hz of HRV; it is in complete synchronization between cyclical change of respiration and interval R-R. ConclusionsThe uniform respiration frequency affects not only high-frequency HRV, but also low-frequency HRV. Therefore, HRV changes brought about by uniform respiration may not reflect the changes of the balance regulation of cardiovascular autonomic nerve. |
