Results from 24 ecg said I have lots of svts, constant ectopic beats and a wandering atrial pacemaker. But that was info over the phone so need to find out implications if I can get to see my doctor within next few weeks. He did not sound unduly concerned, but then he wouldn't, would he? Half an atenolol takes my pulse down. I've also has a few BP spikes to 160/105 but quite short lived. So I am worried as I need to know things. My heart always feels better when I go for a walk, it's sitting around I feel it is struggling, maybe at 68 it is. I suppose the very worst scenario is that it stops altogether.
