Hello, my dad has a pacemaker fitted last Thursday and he has been recovering well. Today, he said he felt a warm sensation internally from the pacemaker, he has been feeling okay all day but I think he was worrying a bit. I put my hand on the pacemaker but I did not feel much warmer then usual? He also has a device that reads his pacemaker and sends the information back to the cardiologist. Should I be worried or is this normal?
