With Lupus, almost anything is possible! However, I must say heart issues are rarely listed among the common issues that are present with Lupus.
I think this question is probably best addressed to your rheumatologist - I'm interested in what disease he was treating for when he prescribed the Plaquenil, and if he suspected it might help the erratic heartbeats.
Let us know what you find out!
