I am 100 percent pacemaker dependent.  My atrial wire was crushed during a mammogram.  I developed atrial fibrillation around the same time.  I still have about 4 years left on my pacemaker.  The doctors say its too risky (infections, etc.) to inserrt a new wire and want to wait until my pacemaker needs to be replaced in 4 years.  I am feeling more debilitated every day.  Do I insist that they replace the wire and pacemaker?
It depends on your indication of pacemaker ...and present ECG...as ventricular lead is there ...until it is working fewer chances of and sudden event...so You’re doctor can take decision of wait and watch confidently. As per indication ....take care
