For practical reasons, the gender factor has been integrated in the a value, yielding to different a values for males and females. LVEDV: left ventricular enddiastolic volume; LVESV: left ventricular endsystolic volume; LVSV: left ventricular stroke volume; LVCO: left ventricular cardiac output; LVM: left ventricular myocardial mass; RVEDV: right ventricular enddiastolic volume; RVESV: right ventricular endsystolic volume; RVSV: right ventricular stroke volume; RVCO: right ventricular cardiac output; RVM: right ventricular myocardial mass.
