My father is vacationing in the Philippines, went to the Dr for cold symptoms, and his heartbeat is 20-30bpm, and an x-ray shows his heart is enlarged. The Dr there wants to give him a pacemaker ASAP and says he may not make the flight back home (Los Angeles, USA - 16hrs) with his condition to get it taken care of here. He is hesitant to get the surgery done in a foreign country and is trying to get back home. How likely is death if he tries to fly back home, or at least to Honolulu (11hrs) to get the surgery? He is 70 years old and in good health besides this surprise.
