In March my Mother had a replacement pacemaker box fitted. As soon as she came back to the ward she complained of intense pain in her sternum, she was told by the nurses that she was suffering from indigestion, they gave her Gaviscon. Although she was still in pain they discharged her two hours later. The pain didn't subside and she started to vomit and was unable to eat, 3 days after the procedure she was back at the hospital (warfarin clinic) and she told them of her symptoms, they told her it was indigestion and she should get herself some Zantac. The following morning - 4 days after the procedure- she complained of the pain and light headness then she collapsed and died at home. She didn't have any pain before the procedure, do you think something has gone wrong during the replacement? She suffered from Atrial Fibrillation and had a "1 wire " pacemaker.She did say that she thought her treatment was particuarly rough compared to when she had her first pacemaker fitted. Help me please make some sense of this?
