Fig. 2. Method of measuring left ventricular diastolic (a) and systolic (b) areas (dotted lines). Left ventricular chamber diameter in diastole and systole (LVIDD, LVIDS) were calculated from cavity areas as: Left ventricular internal diameter=2 ${surd}$ (left ventricular internal area/ ${pi}$ ). Myocardial thickness in diastole and systole (MTD, MTS) were calculated from left ventricular internal and external areas as: Myocardial thickness= ${surd}$ (left ventricular external area/ ${pi}$ )-left ventricular internal diameter/2. RV=right ventricle; IVS=interventricular septum.
