MIMISAN 404 Posted July 29, 2015 My heart Dr. required me to have a pet scan because I have supraventricular tachycardia. He wanted this before he could give my doctor the ok as a low risk surgery person. Anyway, I was terrified of this and had put it off for years. Went in the morning at 8:30 and the whole thing took about an hour. After all my fear it was fairly easy. My only side effect was a low grade headache and now its behind me! Yea me!
