Heart Rate (HR), Interventricular septal thickness (IVS), left ventricular internal diameter (LVID), and left ventricular posterior wall thickness (LVPW) in diastole (d) and systole (s). Fractional shortening (FS%), left ventricular ejection fraction (EF%), Endsystolic volume index (ESVI), Enddiastolic volume index (EDVI). Aortic root diameter (Ao), left atrial diameter (LA), left atrial to aortic root ratio (LA/Ao). Mitral valve inflow (E peak velocity—EVmax, E/A ratio), aortic peak velocity (AoVmax) and peak gradient (AoGmax), peak velocity of mitral and tricuspid regurgitations (MR and TR). Data have been ordered as commonly stored during echocardiography.
