I should have put that sorry; BS ICD and 2 Guidant Leads. I read a few places about the leads being too close to the unit early on will cause problems and make the device seat in too closely to the unit making noise (I think that's the explanation).
I think with my problem is lead placement has always been too high...but then it's quirky, impedance will be high then 3 months later lowered then go really high which perplexes the dr's since they say they were supposed to be sutured in and tight by 6 months out.
hopefully I'll have enough info for the new EP in a couple of weeks and get this figured out; I'm just worried it won't work when it needs to because it senses noise when really my heart's being cranky like in June.
After having a good read, there does seem to be a lot of mention about your ICD. How Boston actually had them approved by the FDA but then changed their method of production for example, causing a recall I think. I did come across a couple of cases where the leads were at fault and not the ICD. One case was the RV lead, and this wasn't made by Boston so they washed their hands of it. From the sound of it, the ICD is likely to be fine, if there's a problem it's more likely to be one of the leads.
