cardiovascular system
• mild systolic dysfunction of the left ventricle (LV), as shown by a reduction in fractional shortening at 5 and 14 weeks of age
• systolic LV wall thickness is significantly decreased at 14 weeks of age
• however, heart rate and heart weight to body weight ratio is normal at both ages
