Radial Pressure Pulse and Heart Rate Variability in Heat- and Cold-Stressed Humans

Figure 3

A typical radial pressure pulse waveform in this experiment. Measures of morphology include AIr, calculated as (late systolic pressure (p2)-diastolic pressure)/(systolic pressure (p1)-diastolic pressure) × 100%, and DAI was calculated as (early diastolic pressure (p3)-diastolicpressure)/(systolic pressure (p1)-diastolic pressure) × 100%. Diastolic pressure was zero in radial pressure pulse waveform.
