This study validated a more exact automated method of determining cardiovascular resonance frequency (RF) against the “stepped” protocol described by Lehrer et al. (Appl Psychophysiol Biofeedback 25(3):177–191, https://doi.org/10.1023/a:1009554825745, 2000; in Foundations of heart rate variability biofeedback: A book of readings, The Association for Applied Psychophysiology and Biofeedback, pp 9–19, 2016). Thirteen participants completed a 15-min RF determination session by each method. The “stepped” protocol assesses HRV in five 3-min stationary windows from 4.5 to 6.5 breaths per minute (bpm), decreasing in 0.5 bpm steps. Multiple criteria, subjectively weighted by the clinician, determines RF. For this study, the proposed method used a sliding window with a fixed rate of change (67.04 ms per breath) at each of 78 breath cycles ranging from 4.25 to 6.75 bpm. Its algorithm analyzes IBI to locate the midpoint of the 1-min region of stable maximum peak-trough variability. RF is quantified from breath duration at that point. The software generates a visual display of superimposed HR and breathing data. Thus, the new method fully automates RF determination. Eleven of the 13 matched pairs fell within the 0.5 bpm resolution of the stepped method. Comparisons of LF power generated by the autoregressive (AR) spectral method showed a strong correlation in LF power production by the stepped and sliding methods (R = 0.751, p = 0.000). The “sliding” pacing protocol was favored by 69% of participants (p < 0.02). The new, fully-automated, method may facilitate both in-person and remote HRV biofeedback training. Software is available open-source.

一种更准确地确定心血管系统的共振频率的方法,以及执行它的程序的评估

这项研究验证了一种更精确的自动化方法,用于根据 Lehrer 等人描述的“阶梯式”协议确定心血管共振频率 (RF)。(Appl Psychophysiol Biofeedback 25(3):177–191, https://doi.org/10.1023/a:1009554825745, 2000;在心率变异性生物反馈的基础:阅读书籍,应用心理生理学和生物反馈协会,第 9-19 页,2016 年)。13 名参与者通过每种方法完成了 15 分钟的 RF 确定会议。“阶梯式”方案在 5 个 3 分钟固定窗口中评估 HRV,从每分钟 4.5 到 6.5 次呼吸 (bpm),以 0.5 bpm 的步长递减。由临床医生主观加权的多个标准确定 RF。在这项研究中,所提出的方法在 78 个呼吸周期中的每一个使用一个具有固定变化率(每次呼吸 67.04 毫秒)的滑动窗口,范围从 4 个。25 至 6.75 bpm。其算法分析 IBI 以定位稳定最大峰谷变异性的 1 分钟区域的中点。RF 是从该点的呼吸持续时间量化的。该软件生成叠加 HR 和呼吸数据的可视化显示。因此,新方法完全自动化了 RF 测定。13 对配对中有 11 对落在阶梯法的 0.5 bpm 分辨率范围内。自回归 (AR) 谱法产生的低频功率的比较表明,步进法和滑动法产生的低频功率有很强的相关性。新方法使射频测定完全自动化。13 对配对中有 11 对落在阶梯法的 0.5 bpm 分辨率范围内。自回归 (AR) 谱法产生的低频功率的比较表明,步进法和滑动法产生的低频功率有很强的相关性。新方法使射频测定完全自动化。13 对配对中有 11 对落在阶梯法的 0.5 bpm 分辨率范围内。自回归 (AR) 谱法产生的低频功率的比较表明,步进法和滑动法产生的低频功率有很强的相关性。R  = 0.751,p  = 0.000)。“滑动”起搏方案受到 69% 的参与者的青睐(p  < 0.02)。新的全自动方法可以促进面对面和远程 HRV 生物反馈培训。软件是开源的。
