I have ask my doctors but want answer my question on that they get very still when metion. im on medience for all this and one is at night so my heart will slow down because if it doesn t it beats differently and feels like its trying to stop but they said it trying to reset it self when it beats like that ...it will beat will hard and then beat normal again it feels like it skipping a beat when this happens. It use to do this once in a while ut now is occasionally now. please give me aa anwers on this illness that I have so I can except the issues and the changes that may happen in the future. thank you janette drake
