Please, you need to speak to the vet that did the imaging so they can explain everything to you. We do not use those same units of measure in the U.S. so I cannot correlate their relevancy. Also the size of the dog needs to be taken into consideration with the measurements and you have not provided that information to us. All I can tell you is that the fractional shortening (FS) is a normal percentage. FS refers to the size of the ventricle and whether it is functioning normally. In general, normal fractional shortening (FS%) is 28%–45% in the dog; your dog's is 41.56% The Ejection fraction (EF) is also normal. EF is a measurement of the percentage of blood leaving your heart each time it contracts. Anything over 55% is normal. Your dog's is 73.61%. I have no idea why they are saying the heart is slow. You need to speak to them directly to get clarification.
