Echocardiographic measurement of left ventricular size and function in diastole and systole in male mice 16 weeks of age

All measurements are in millimeters and were performed on M-mode images acquired with conscious mice. n = 4, mean ± S.E., Student's t test. IVS is interventricular septum; LVID is left ventricular internal dimension; LVPW is left ventricular posterior wall; d is diastole; s is systole.
