He is alright. He is home. The stress test showed what great shape he is in. If you asked me they didn't test him with the correct stress. They needed to do the test with difficult child standing in the room yelling. Anyway they did talk to husband about breathing and working on dealing with the stress on his body due to difficult child and other issues in husband's life. He is going to bed now (husband) and difficult child is already asleep. A relaxing evening. Thanks for your thoughts and prayers.
