Hi, I just got a Pacemaker and I am noticing very slight dizziness but today I tried to do some weeding and got very dizzy from bending over. It took me about 15 minutes to get over it. I see my Cardiologist for the first time since getting it on Monday. Should I be concerned. The Pacemaker was installed due to fainting. I have a heart monitor in my chest. The heart monitor showed that when I passed out my heart stopped for 9 sec. Now I am dealing with dizziness. Thanks for any input.
