Had my 4th box change yesterday on my dual PM, when I was in the recovery room I passed out 5 times, the Dr came out of theater to see me, the pacing team said I have. Noise on my Atrium lead ans is causing my ventricle to become confused so it won't pace, this is serious as I am 100 dependant. The Dr has turned off the atrium lead and they have reprogrammed my PM in DDD mode (I don't understand what this is) Dr says I should be OK with just the ventricular lead as pm was fitted due to low heart beat leading to blackouts. Nurse asked if I could have someone with me for the next two weeks just to be on the safe side, I have now come home and feeling very scared and confused I don't understand what is happening,I had just come around after a general so wasn't in a fit state to ask questionsi have had 2 leads for 23years and now only one will i be OK Dr gone on holiday for two weeks so not around to speak to me. I have a pacing app in two weeks. I am so anxious, scared and in pain as it was put under muscle.
