Battery running low and optimization.
My ICD battery is quickly losing voltage. In early November it was 9 months, mid November was 5 months, last week 2 months! I will be changing from Medtronic to St Jude, as that's the hospital's device contract. I am PM dependent due to SSS with no heartbeat when he brings it down to 30 bpm. I have diastolic disfunction with a stiffening and thickening heart/ideopathic cardiomyopathy. I had an optimization again last week, working on synchronizing my heartbeat. EP spent about 2 1/2 hours trying to synchronize, which was unsuccessful but he did the best he could. He changed from trying to synchronize the right side to the left side. He said I should get more blood into my lungs to reduce SOB and more blood to my LV. He said he's never done an optimization this way and he will keep a close watch on my heart function and report any symptoms. I asked him about the effect on the LV and he said he didn't know and he would watch for changes. I have always sent at least a weekly Carelink. Afterwards I had an EKG and he had me take a photo of it with my phone and said if I have an EKG taken to let them see your EKG on your phone or they'll immediately send me to cardiac ICU. He's hoping I can get a third lead, but my EF not low enough to fit the criteria. Awaiting for biopsy results and will appeal for a 3rd lead before he replaces my device.
