Hi Melissa ...and Welcome!

Sorry to hear your EKG is causing concern. Cardio will get to the bottom of it. How is your MG? What meds are you taking? Is there any chance your meds are involved?

Hyperkalemia (too much potassium) can effect P-waves - - has any one checked your electrolytes?

Pls. let us know what cardio says...try not to worry 'til then.

Sue
