Heart function determined by ejection fraction (EF) and fractional shortening (FS). Heart size in diastole (d) and systole (s) represented by left ventricular anterior wall (LVAW) thickness, left ventricular internal diameter (LVID), left ventricular posterior wall (LVPW) thickness, left ventricle (LV) volume and LV mass in Aase and Bellomo VEGF-B-/- and littermate control mice. ECG recordings are shown as PQ, QRS and QT interval, heart rate in beats per minute (bpm) and amplitudes of P and R peak. Results are expressed as mean ± S.E.M. n = 4–9.
