Finally, a cardiologist who is comfortable with the outputs from an Apple Watch. And one who understands and appreciates, as an athlete, my need to exercise. Especially, I valued his willingness to be a listener, not a talker.
I couldn't expect like this wonderful attention. Everybody were so nice especially Dr. Limberg and Dr. Hsi. They are professionals. I am very helpful that they got me.
