Side effects from the pacemaker

Hi on 10/13/08 my mother had a pacemaker placed because her HR was 27 bpm. After the surgery she has been dizzy, confused and forgets thing, depress, emotional. She has not been back to work yet because she is a medication nurse. We have had a EEG, CAT Scan done and nothing has shown up. Where do we go from here?  I was also wondering can the pacemaker be set to high they have it set at 60 bpm.? They are trying to tell us that it might be her inner ear I do not believe it.

Have you found out how much her pacemaker is working?  If it is working at 100%, she could have these symptoms.  My mom's pacemaker was working at 100% when sitting and a little less than 100% when walking around.  She was dizzy, confused, forgot things, tired, and depressed.

Yes, it is working at 100%. When I was at the doctors office they explained that it is working everytime her heart beats. They told us that the lower right side of  her heart is bad. They said the pacemaker is set at 60bpm to keep her heart at a steady beat but when her blood pressure is taken the lower number is always in the 80's.  I tryed to ask could the pacemaker be set to high for her body.
