Tracey, I am wondering if you happen to have a sjogrens diagnosis. There are quite a few people that have types of erratic, tachycardia(rapid heartrate) and other little issues that can confuse the doctors.

People with myasthenia gravis can have sjogrens as their tagalong AID. I would ask your doc to make sure he has covered all the bases of as it can be hard to pinpoint the heart issues with sjogrens. Good luck. gto
