I’ve been dealing with kind of a sudden onset bradycardia, HR low 50’s to 60, and trying to figure out why its happening. I had an EKG today and the nothing abnormal other than the slow heart rate. I have been diagnosed with Sjogren’s and carry anti-Ro antibodies. I don’t know if I carry anti-cardiolipin antibodies. Here’s 1 case report of anti-Ro causing arrhythmia: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3110856/
If anyone has heard of this, or has it, please share it. Thanks.
