Man alive, that's a mess of trouble at once. If it's any reassurance my mother's pacemaker installation went off smooth as an oil change & she was up & feeling fine-ish four days later. According to her they sent her to a unit that did nothing but pacemakers & it was like pulling into a Jiffy-Lube for an oil change: six people were resting on beds in various stages of preparation, someone would come in & call "Next!" & they would take you out, *NASCAR torque wrench noises*, you'd get moved into recovery, "Next!"
