在这项研究中，采用每分钟 3、4、6、8、10、12 和 14 次呼吸的呼吸频率来研究这些频率对心率变异性 (HRV) 的影响。对 3 名女性志愿者在每种呼吸频率下收集了 16 次数据，对 2 名女性志愿者收集了 12 次数据。尽管这些呼吸频率之间的平均心率没有差异，但每分钟 4 次和 6 次呼吸时呼吸诱发的谷值心率显着低于每分钟 14 次呼吸时的心率。较慢的呼吸频率通常比较快的呼吸频率产生更高的 HRV 幅度。然而，最高振幅为每分钟 4 次呼吸。 HRV 幅度以每分钟 3 次呼吸的速度下降。结果被解释为反映了乙酰胆碱代谢速度缓慢的可能影响以及每分钟 3 个周期的负共振的影响。
In this study respiratory rates of 3, 4, 6, 8, 10, 12, and 14 breaths per minute were employed to investigate the effects of these rates on heart rate variability (HRV). Data were collected 16 times at each respiratory rate on 3 female volunteers, and 12 times on 2 female volunteers. Although mean heart rates did not differ among these respiratory rates, respiratory-induced trough heart rates at 4 and 6 breaths per minute were significantly lower than those at 14 breaths per minute. Slower respiratory rates usually produced higher amplitudes of HRV than did faster respiratory rates. However, the highest amplitudes were at 4 breaths per minute. HRV amplitude decreased at 3 breaths per minute. The results are interpreted as reflecting the possible effects of the slow rate of acetylcholine metabolism and the effect of negative resonance at 3 cycles per minute.
