Last EKG wasn't normal, have been having SVT's and PVC's for years. Sometimes I am about to faint. Landed in ER's too many times. Cardio docs have all told me it's not bad. The last echo I did showed worsening of thickened mitral leaflets and the EF is now at an all time high of 76%. My appointment with yet another cardio doc is a while away. Can anyone explain this to me? Most of the day I am in a chair and breathless. My hands are both ice cold and there are signs of bruising along the veins. Rheum doctor believes this is all connected to circulation.
