In each PACU I've worked in, situations like that were handled "silently," meaning that there was no overhead page, etc. Since we are all supposed to be ACLS certified, and our anesthesiologists are readily available to us, it's normal for us to monitor and manage those situations without outside assistance. We would, of course, notify the cardiologist involved immediately, but it sounds like that was done and he was aware and ok with her management. We pretty much are our own RRT in PACU.
