A son of a friend of mine has a heart condition that hehas a pacemaker for and takes medication. He passed out and was medi-vac d to the hospital. He is in ICU now and is showing signs of swelling of the brain. not sure how long he was out before they realized that he didn t just pass out but was not breathing. what are symptoms to be watching out for and what would make him not a good recipient for a heart transplant due to this event?
