Echocardiographic evidence for moderate LV hypertrophy induced by prolonged (3-day) β-AR stimulation.

Effect of permanent 3-days s.c. ISO infusion in male wildtype mice on regional dimension of (A) IVS, (B) LVAW and (C) LVPW, (D) LVID and (E) LV volume in end-diastole and end-systole and on (F) LV performance, as assessed by EF, FS and (G) heart rate. Saline-infused mice served as control. Animal numbers per treatment n = 9; values are shown as mean ± SE, *p < 0.05 vs. Control; unpaired student's t-test.
