通过皮肤进行的耳道迷走神经刺激 (taVNS) 增加了心脏的副交感音调,而度亚太解压 (OA-D) 则轻微降低了交感音调. 一个新的心率变化 (HRV) 模型澄清了自主反应.
科学领域:
- 自主神经系统生理学 自主神经系统生理学
- 心血管监管 监管心血管系统
- 非侵入性神经调节 无侵袭性神经调节
背景情况:
- 解释对干预的自主反应,如通过皮肤进行耳道迷走神经刺激 (taVNS) 和使用心率变化 (HRV) 的骨科医生操纵技术,由于方法不一致,这一直是个挑战.
- 要准确评估自主效应,需要基于鼻腔节点自动性的HRV解释的新型机制框架.
研究的目的:
- 开发和应用一种解释HRV的机制模型,以区分自主反应.
- 为了研究taVNS和 occipitoatlantal减压 (OA-D) 对健康成年人的心脏自主声调的影响.
主要方法:
- 开发了鼻节自动性的机械模型来解释HRV参数.
- 在连续3天内,将该模型应用于健康成年人的休息,taVNS和OA-D干预期间的ECG记录.
- 验证了模型使用低频 (LF) 和高频 (HF) HRV组件区分同情和寄同情音调的能力.
主要成果:
- 模型模拟表明,LF HRV最好从心率来预测交感声调,而HF HRV最好从心率来预测副交感声调.
- taVNS显著增加了心脏的副交感音调.
- OA-D导致心脏交感音调轻微下降.
结论:
- 开发的机械 HRV 模型为解释对神经调节和手动疗法的自主反应提供了可靠的框架.
- 塔VNS增强了副交感活动,而OA-D具有轻微的交感效应.
- 准确的HRV解释对于理解非侵入性干预的生理影响至关重要.

ECG Interpretation of Rhythms
Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....

Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
Assessment of apical pulse
Assessing the apical pulse is a critical nursing procedure, particularly indicated for:
Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
