Lak,
Thanks for the post.
Systemic Lupus Erythematosus (SLE, or Lupus) is not a primary cardiologic disorder. You may wish to post your question on the Rheumatology site to learn more about the proper diagnostic criteria, long-term outcome, ANA levels, etc.
Cardiac manifestations vary from patient to patient, for some they are a major compnent of the disorder, but for others not that prominent. The cardiac manifestations that are described usually do not include arrhythmias as a prominent manifestation. Typical cardiac manifestations include pericarditis, myocarditis, pulmonary hypertension, and Libman-Sachs endocarditis.
Establishing the diagnosis of Lupus should be done by a rheumatologist or experienced internist. The diagnosis is tricky and relies more on the clinical symptoms/signs than it does on lab work.
I'm sorry to not be able to provide more, but this is simply not a diagnosis that falls under the realm of diseases that cardiologists frequently see.
Hope that helps.

Please don't worry about an elevated sed rate if you had just had a chest cold. I mean, certainly discuss it with your doctor but I'm assuming he or she said it was elevated a bit, not something extraordinarily high. A Sed rate is a very non-specific test, mostly indicating inflammation. It is perfectly normal for it to have been a little elevated if you had a chest cold with some inflammation.
You can have lupus with a negative ANA but that's pretty unusual. I think you are worrying way too much!
Good luck.
doctor can't figure out what is causing low potassium,low blood pressure or tingling in hands,calves,head, chest,back shoulders any idea. I've been in hospital 8 times in 12 weeks with no results and still feeling bad.
