High altitude heart rate

WebBackground: Heart rate variability (HRV) during sleep in normal subjects at high altitude shows a decrease in parasympathetic tone associated with an increase in the sympathetic one, which tends to be reversed with acclimatization. However, periodic breathing (PB) during sleep may influence this effect detected by HRV spectral analysis. Web29 de out. de 2024 · How much higher is your heart rate at altitude? At sea level, oxygen saturation hovers around 98 to 100 percent, but at 14,000 feet, the saturation levels drops to 80 percent due to oxygen-poor air, requiring the heart to increase cardiac output, requiring a 10 to 30 percent increase in heart rate to maintain appropriate oxygen delivery to tissues.
