Yea those Palps are very, very scary. They cause me to panic too, especially if I'm just sitting there. It was weird cause I play basketball a lot and I was wondering if there was something seriously wrong with my heart. I have them every now and then, but only mainly at work which puzzles me, I guess you can say stress LOL. They put me on a light dose of Toprol, but it doesnt help much. I am going to have yearly checkups to check my murmur.
