在COVID-19后的学生中,体育活动显著改变了心率变化,这表明潜在的心脏和神经系统影响. 这突显了康复个体的同情度和心血管应变的增加.
科学领域:
- 心脏病学 心脏病学
- 运动医学 运动医学
- 自主神经系统研究 自主神经系统研究
背景情况:
- COVID-19 感染可能导致长期的心血管并发症.
- 自主神经系统的失调是COVID-19后的一个潜在问题.
- 了解COVID-19后个体对身体活动的心脏反应至关重要.
研究的目的:
- 为了调查COVID-19感染后学生的心率变化 (HRV) 指标.
- 评估身体活动后的心脏并发症和自主神经系统功能.
- 在COVID-19后的队列中,在运动后识别HRV参数的变化.
主要方法:
- 在使用自行车人体表仪进行5分钟的体力活动后,探索了11个心率变化指标.
- 使用电心电图 (ECG) 记录通过变量脉计.
- 分析了ECG数据,使用专门的计算机程序 ("心脏reg"",心脏prog").
主要成果:
- 与对照组相比,COVID-19学生的心律调节指数显著增加 (p<0.05).
- 活动后,交感声调指标 (压力指数,VBI,VRI,LF/HF) 增加,而心脏间隔变化系数下降.
- 在感染群体体体育活动后,心电图显示了心脏功能障碍和心动减速.
结论:
- 短期的体力活动将心血管指标转移到COVID-19后的"紧张区域".
- COVID-19对心血管和神经系统的能力产生了负面影响,影响了运动反应.
- 这些发现加深了对患有COVID-19后心血管功能障碍的年轻成年人HRV变化的理解.

Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...
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.
Pre-Procedural Preparation
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:
Assessment of apical pulse
Assessing the apical pulse is a critical nursing procedure, particularly indicated for:
Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...
