The ultrasound test is pretty cool from what I recall. Mine was in color and it was intriguing seeing the moving parts. My test was inconclusive so they decided to do the heart cath.
The heart cath was pretty straight forward and probably even more routine today than it was 30 years ago. You’re awake during the procedure and it was interesting seeing the dye move through your body. The fluid travels very quickly and feels warm where it travels. Noticeably warmer in the brain and groin areas!! It was most comforting for me to see that all veins and arteries were clear. Just additional information should the physicians determine they’d like for you to have one.
Rest up and good luck!
