Got back from the Cardiologist appointment a little bit ago.  The doc did the EKG and echocardiogram which gave him a clearer picture of the heart.  I made sure to bring to his attention the edema (water retention) which is has been occurring for a couple months now.  So he asked if it was alright to put Lasix on board. Now he asks rather than assuming I am going along with everything and I am glad he respects that. Lasix is a diuretic and it will be given to him on an as needed basis. Also Kody came home with a Halter monitor for the next 24 hours.  This will give him a better idea of how Kody's daily activities are.  I will update more when the results of that come back.
