Why the study?
Does heat and cold stress alter radial pressure pulse and heart rate variability in healthy subjects?
Does heat and cold stress alter radial pressure pulse and heart rate variability in healthy subjects?
Heat and cold stress induce opposite changes in radial augmentation index and high-frequency spectral energy of the radial pressure pulse, highlighting the physiological relevance of the 10-50 Hz spectral region.
No takes yet. Share an insight, caveat, or question.
Thermal effects on radial pulse indices in healthy adults should not change practice; leaves open utility of 10-50 Hz spectral analysis.
Huang et al. (2010) studied this question.
