I lift three days a week and do cardio three days a week and I have been
having "missed" beats regularly for about five months.  I feel them.  They
occur when I am resting. (i.e. slower pulse)   I don't have them working out
or moving around.  I had a cardiac profile done last March and got a clean
bill of health.  Any thoughts on this???  Oliva
