Anne: > Victor (around 5-6 years old) seems to have tachycardia tonight... Anne, the large abdomen and the weakness may suggest a number of things, but he most likely of all of them is heart disease. Of course, it could just be weight gain from the prednisone. At any rate, knowing how close you are to Victor - I think it would be worthwhile to take him in for an exam and an X-ray to make sure he's not acumulating fluid in his abdomen because his heart is pumping efficiently.
