Reducing Anxiety and Heart Rate

"Gotta tell you I used the breath work to a great advantage a couple of weeks ago.  I had to have emergency oral surgery.  I was hooked up to EKG and BP cuff.  I was not prepared mentally it emotionally for going under the knife or anesthesia.  Everything was elevated.  I felt horrible anxiety laying there waiting. Watching my blood pressure at 155/120.  (Way higher than normal) and heart rate 101-110.  So, all I could do was to breathe.  And I brought everything down into the normal zone in less than  10 minutes. Might have taken less time but I was being poked etc.  and anxiety disappeared too. Whew!!"
