In addition to my questionable MVP diagnosis, the EKG I got last week came back in the report with all normal except a "mild intra-atrial conduction defect". Does anyone know what this means?
This means that the conduction between right and left atrium if prolonged. Clinically this does not mean a lot.
I would not worry too much. If you had a normal echo (except for MVP) it would be very reasuring.
