Melissa.

I'm very sorry to hear of your heart issues. It is quite unfortunate.

Yet the only information I have is personal experience. So. I also had a thmyectomy, and now have trachacardia and irregular heart beats and random weakness not due to mg. They have not yet found what is wrong. But they are working on it so I'm not sure if they did someting by accident during surgery or what. Yet I feel your uneasyness.

Please let me know how things work out
