ICD lead threshold increase - Cardiac Sarcoid
Just got back from the cardiologist. He interogated my newly implanted biventricular ICD ( Nov 8, 2018) and noted and increase in RV threshold voltage from 1.5 to 2.0V. What would cause this? He told me to discuss it with the doctor treating my Sarcoid. I was diagnosed with Cardiac Sarcoid in 2013 and have had an ICD since then. Could this be an indication of increased sarcoid activity in my heart? I have been on prednisone, tappered from 20 to 8 mg/day.
Can anyone shed some light on this for me.
