2. A sense of security that now you have a safe reliable life-saving device implanted that will also improve your quality of life.
3. Infection risks, mainly at implant.
4. Rarely, removal of the device and leads if they become infected. This may require difficult lead extraction procedures.
4. Discomfort at implant site.
5. Necessity to monitor regularly.
6. Availability of remote monitoring so that your doctor will know in real time if anything is wrong.
6A. Confusion about remote monitoring in elderly patients.
7. Possibility of device malfunction or lead problems that may require revision of the implant.
8. Necessity to reprogram the device periodically to enable more effective control of the arrhythmia and heart function.
9. Necessity to replace the battery periodically, usually after at least 5 years, often much longer.
10. Necessity to upgrade the device as your father's condition changes.
There are other side effects but I would like to emphasize that, whatever the problems and they are not common, pacemakers are miraculous devices that save lives and enable improved quality of life. Just make sure that the doctor implanting the pacemaker is experienced and has a good track record and that the doctor following your father's device is experienced, responsible, honest, conscientious, and caring. These two doctors may be the same or different people.
