I had 2 ECG graphs done in the past two years and they both show a
slight deviation.   I asked my doctor about the graph.  He said there
is a slight irregularity but, it maybe normal for me, but he does not
have an older ECG to compare it to.   He said that it's probably
nothing to worry about.   He said, that a cardiologist doctor would
know better how to read my ECG.    But he did not refer me to a
cardiologist because there was no good reason to do so.      I am
constantly tired and my doctor can't find out why (apparently I am in
great health).    I was curious if an abnormal hear beat to be a cause
of constant tiredness?     thank, here is a picture of my ecg.
