Left ventricular internal diameter: wall thickness ratio and the left atrial-to-aortic root diameter ratio in healthy domestic swine according to their body weight in 10 kg increments. LVIDd - internal left ventricular dimensions at end-diastole; IVSd - end-diastolic thickness of the interventricular septum; LVIDs - internal left ventricular dimensions at end-systole; IVSs - end-systolic thickness of the interventricular septum; LPWs – left ventricular posterior wall in end-systole; LA/Ao - left atrial-to-aortic root diameter ratio.
