hi ,my brother is 21 and had his pace maker removed after a week of being fitted due to infection ,his heart is very complex and im concernd about haveing another fitted on the other side as he,s suffering from regurtation to the lungs and they dont know if the regurtation to the lungs may get worse ,but maybe ok with a complex pace maker which they were unable to insert all the wires previous ,also his arm is swelling now and is on a suction to loose the virus at the moment
