I had my pacemaker, a St. Jude Identity XL DR, implanted on July 4th. I was looking at the paper printout of the settings they gave me and I noticed that there were 2 columns. One column labeled 'initial' and the other labeled 'actual'.
In a few cases the figures were not the same. For example, in the Ventricular Stimulation configuration the initial figure is set as unipolar and the actual column indicates bipolar. Another example is the max hear rate is 110 in the initial column and 130 in the actual.
Can anyone fill me in on what the difference is between these two columns. Also, what is the difference between unipolar and bipolar?
