I thought I was doing so well and now my heart is pumping away at 140 ! No doctors appt available typical so panic is setting in . Had my cardio version last August and all was going well until this week when I've been getting out of breath and tired , that feeling of your legs turning to lead , and I've felt my heart fluttering , but irregular. Decided to put my keep fit heart monitor on and low and behold 140 , when it's been 70's . Here we go again . I shall pop into the surgery to use the blood pressure machine and at least the receptionist said if it was that high ' a doctor will see you ' , fingers crossed . Any words of wisdom ?
