概括
与对照组相比,通过皮肤进行的迷走神经刺激 (taVNS) 并没有改善主要抑郁症 (MDD) 患者的结果. 然而,根据基线阴道声调 (RMSSD) 的分层揭示了taVNS对低RMSSD个体的好处,这表明了个性化的治疗方法.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 心脏病学 心脏病学
背景情况:
- 大型抑郁症 (MDD) 与自主功能障碍有关,其特征是交感过度激活和副交感衰减.
- 穿皮漫神经刺激 (taVNS) 是一种非侵入性方法,用于调节副交感系统并恢复自主平衡.
研究的目的:
- 研究taVNS对MDD患者和对照者的情绪,心脏和炎症反应对MDD患者和对照者的急性压力的影响.
- 探索基线阴道声调的实用性,通过RMSSD测量,用于对taVNS的分层治疗反应.
主要方法:
- 一个单盲,交叉,随机对照试验,涉及110名参与者 (59名MDD,51名对照).
- 在急性压力模式下,参与者接受了活跃的taVNS和假刺激.
- 后期分析根据基线RMSSD (低与高) 对参与者进行了分层分类,并分析了连续的RMSSD效应.
主要成果:
- 在使用taVNS的MDD患者和对照人群之间没有观察到结果的显著差异.
- 在低RMSSD组中,taVNS使心脏应激反应正常化,并降低了TNF-α水平.
- 在高RMSSD组中,taVNS增加了心率,TNF-α,并降低了心率变化率 (HRV).
结论:
- 仅凭诊断标准可能无法预测taVNS在MDD中的疗效.
- 基于RMSSD的分层是个性化 (ta) VNS治疗结果的一个有希望的方法.
- 鼓励进行进一步的研究,使用RMSSD分层重新评估HRV数据.

Factors Influencing Heart Rate
6.1K
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

Decreased pulse rate

Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...
