Echogram stress test today

Wow that was very uncomfortable. I had to have a IV and they put some solution in to see my heart. Then you walk and then you walk faster on the treadmill and then faster. Then you jump off and your heart is racing and they make you hold your breath. Very hard to do when you can't catch your breath. Then they press very hard with the ultrasound probe until it hurts for about 40 minutes. I am wiped out today. Well I hope everything is ok and I still have my surgery on September 4th. Judy
