(L-R): Echocardiograms of the bat’s heart, showing before and after dobutamine administration respectively. (IMAGE)
Caption
Still images taken of the echocardiograms (i.e. ultrasound to create images of the heart) of the bat’s heart. They show the two-dimensional (2D) short-axis view of the left ventricle (LV) chamber, before and after dobutamine administration. Both images show a moment during a contraction of the bat’s heart.
On the left image, there is a small gap in the middle of the LV chamber during a contraction of the heart. On the right, the LV chamber is completely closed during contraction, suggesting a more powerful pump of blood.
