Congratulations on a nice trip to our side of the moutain. The pacemaker may indeed by temporary. Your job now is to rest, walk, and breathe into your plastic thingy!
Welcome to recovery. I hope everything goes smoothly from now on. I had a temporary pacemaker but it was removed after a few days. They were worried about my heart rate going below 40 bpm (which it has done a few times since)
