Abstract

Background: There isevidence that device-guided slow breathing using biofeedback acutely reduces blood pressure (BP) and pulse wave velocity [i.e. increased pulse arrival time (PAT)].

Objectives: The objectives of the study presented here were to test whether the results of changes observed in PAT in earlier studies are reproducible over 1 week and how changes in pulse wave velocity/PAT translate into absolute self-measured BP changes.

Methods: Patients with a systolic BP 130-160 mmHg or treated essential hypertension (21 females/23 males) were trained to perform unattended device-guided slow breathing exercises for 10 min daily over 5 days. Furthermore, they were skilled to perform self-measurement of BP before and after the breathing exercise using a validated upper-arm device.

Results: Office BP at screening [median (1, 3. Q)] was 137 (132, 142)/83 (79, 87) mmHg. We observed a significant ( P < 0.05) increase in PAT of 5 ms (SD 12.5 ms) on average after 10 min of guided breathing and an additional 1 ms ( P < 0.05, SD 8 ms) during the following 5 min of spontaneous breathing compared to baseline. PAT before the exercise remained constant over 5 days paralleled by constant self-measured BP before the exercise. Device-guided breathing was associated with a significant reduction of self-measured SBP of 5 mmHg ( P < 0.01, SD 8 mmHg). Data furthermore demonstrated that these changes were highly reproducible over 1 week.

Conclusions: Device-guided slow breathing and biofeedback lead to reproducible and favorable changes (increase) in PAT and SBP (decrease).

设备引导的缓慢呼吸与脉搏波速度的直接生物反馈-对脉搏到达时间和自测血压的急性影响。

背景：有证据表明，使用生物反馈的设备引导的慢呼吸可以显著降低血压（BP）和脉搏波速度[即增加脉搏到达时间（PAT）] 周，以及脉搏波速度/PAT的变化如何转化为绝对自行测量的BP变化。方法：收缩压为130-160的患者 mmHg或接受治疗的原发性高血压患者（21名女性/23名男性）接受训练，在无人看管的设备引导下进行10次缓慢呼吸练习每天5分钟以上天。此外，他们熟练地使用经验证的上臂装置在呼吸练习前后进行血压的自我测量。结果：筛查时Office BP[中位数（1。Q） ]为137（132142）/83（7987）mmHg。我们观察到显著的（P 结论：装置引导的缓慢呼吸和生物反馈可导致PAT和SBP的可重复且有利的变化（增加）（减少）。

期刊介绍： Blood Pressure Monitoring is devoted to original research in blood pressure measurement and blood pressure variability. It includes device technology, analytical methodology of blood pressure over time and its variability, clinical trials - including, but not limited to, pharmacology - involving blood pressure monitoring, blood pressure reactivity, patient evaluation, and outcomes and effectiveness research. This innovative journal contains papers dealing with all aspects of manual, automated, and ambulatory monitoring. Basic and clinical science papers are considered although the emphasis is on clinical medicine. Submitted articles undergo a preliminary review by the editor. Some articles may be returned to authors without further consideration. Those being considered for publication will undergo further assessment and peer-review by the editors and those invited to do so from a reviewer pool.
