In this paper, I present age-compensated formulae for finding MR-R and CVR-R of healthy subjects resting in a supine position, CVR-R of healthy subjects breathing deeply, and CVR-R of healthy subjects standing upright.1) Age-compensated formula for finding MR-R of healthy subjects resting in supine position:Y=126.153-16.187*LogeX (X: age)2) Age-compensated formula for finding CVR-R of healthy subjects resting in supine position:Y=10.818-1.993*LogeX (X: age)3) Age-compensated formula for finding CVR-R of healthy subjects breathing deeply:Y=24.293-4.738*LogeX (X: age)4) Age-compensated formula for finding CVR-R of healthy subjects standing upright:Y=7.389-1.277*LogeX (X: age)How the autonomic nerve activities in the heart of subjects resting in supine position, breathing deeply, and standing upright are evaluated using the MCV Graph Method is described here. (MCV Graph Method stands for Mean and Coefficient Variation Graph Method.) Plotting of M and CV data measured by an ECG R-R Checker or a Plethysmograph P-P Checker on an MCV Graph, which is a quite new and easy-to-observe method, enables synthetic evaluation of both sympathetic and parasympathetic nerve functions. The MCV Graph Method can be used for measurement under various loads.
