Volume of the Heart:
Briefly, in the early days of M mode echocardiography, the
volumes of cardiac chambers were calculated by cubing the chamber diameter
(cube rule). That method overestimated the true volume; Teichholz method
corrects for that overestimate.
CUBE RULE >>>> V = D3
TEICHHOLZ >>>> V = [7.0/(2.4 + D)] * D3
where V = volume and D = diameter.
