This article discusses two PD patients that previously had cardiac pacemakers placed for heart conditions that later underwent DBS STN. Considerations had to be made for placement of the DBS STN generator, sensor difficulties and device interference, and inability to use MRI (magnetic resonance imaging) to guide surgical placement of the DBS STN. Both patients experienced an improvement in their ParkinsonÕs as a result of the DBS STN surgery. After extensive monitored testing of the DBS STN, neither patient experienced any interference of the DBS STN with his/her pacemaker. The authors note that there have been documented cases of undesirable interaction of DBS STN and pacemakers, but suggest with surgical modifications and presurgical monitoring patients with pacemakers may be suitable candidates for DBS STN.
