I have been batteling these irregular heartbeats for many many years.......What I don't understand is that they or the anxiety will stay away for quite a while.......then as happened this past April, back they came with a vengence......since April I have had an EKG,Stress Test, Echo Cardiogram and they all have come back normal........then the anxiety and stress and irregular heart beats......what comes first ???stress or irregular heartbeats, or do the irregular heartbeats cause the anxiety ???? I'm very tired of this and the more I try to calm down and stop these skipped beats, it seems the more they happen........any help or advice is needed.....please.........thanks Steve
