Pulse rate

Maybe co-incidence but I am taking Ropinirole (8mg daily) and have noticed a drop in pulse rate. has anyone had a similar experience?
I do not measure my pulse rate but I take 8mg ropinirole and I did notice one yellow foot and one purple one in the shower every morning. I thought I was doing a fair amount of execise but I now do a daily session on an exercise bike, which is nothing like as tiring as walking. This seems to have helped with my circulation.
