  • atrial fibrillation episodes

    hi all,

    i had my icd interrogated today after a longer period than advised--delay due to a move and doctor/insurance change. the device is working fine and while there have been no ventricular events the medtronic tech reported that i do seem to have had a number of episodes of a-fib (more than have been reported in any previous interrogation). he said that these were all very minor episodes, with the longest one lasting barely over a minute, and the icd didn't need to respond in any way. according to him a-fib only becomes a problem when it is sustained for much longer periods of time (in the hours rather than minutes) and that as far as he knows this level of a-fib is not something i need to worry about. then again he isn't a cardiologist. speaking of cardiologists, i won't be seeing my new one till january (and i'm not sure either if i'll stick with him--he's not a hcm specialist but i'm having a tough time finding one here in denver/boulder).

    thoughts anyone?

    Re: atrial fibrillation episodes

    Well, the doctor is right in that less than a minute is not really a big problem. The concern is that there are more episodes than before and this could be a trend of increasing afib. And if the afib starts to creep up and be for longer periods of time, then you have a serious problem.

    However, if the ICD is set to cardiovert you when you go into afib, then you are cool. I would check and confirm that it will fix the afib. You don't want afib to go for more than a day, as if you go back into sinus (normal) rhythm after a long stretch (at least a day or two) of afib, then you can have a stroke.

    take care,
