Why the study?
Do changes in supine heart rate variability at 2400 m altitude predict acute mountain sickness on further ascent to 3000-4300 m?
Do changes in supine heart rate variability at 2400 m altitude predict acute mountain sickness on further ascent to 3000-4300 m?
Analyses of supine heart rate variability at 2400 m could offer potential markers for identifying climbers at risk for acute mountain sickness at higher altitudes.
Supine HRV changes at 2400 m may flag AMS risk on ascent; hypothesis-generating and requires prospective validation before clinical use.
Changes in supine HRV parameters at 2400 m were related to AMS at 3000-4300 m Thus, analyses of HRV could offer potential markers for identifying the climbers at risk for AMS.
