I am a 42 year old male who is very anxious about his health, though to everyone else I appear well and healthy.

I got a couple of periods of Atrial Heart Fibrulation a while back but my heart went back to normal. I had lots of tests done and these were all normal.

I panic when I get ectopic beats. I know these can be normal but my doctor panicked me when he said I shouldn't get these during exercise and if I did it could be serious. Now when I go for a run I become super aware of my heart beating.

I think it jumped yesterday once when jogging very lightly when not out of breath at all and once today when stopping for a minute after running.

If I run hard I don't notice anything at all wrong.

Please help could do with some reassurance

Thanks
