Mirza et al reported two equations for estimating the 2-minute walking distance (@MWD) for adult Malaysians. The authors are from Curtin University in Australia.
Patient selection: Malaysian 40 to 75 years of age
Parameters:
(1) gender
(2) age in years (female 0, male 1)
(3) resting heart rate in beats per minute
(4) peak heart rate in beats per minute
change in heart rate =
= (peak heart rate) - (resting heart rate)
estimated distance in meters =
= (31.2 * (points for gender)) - (1.1 * (age)) + (change in heart rate) + 196
