Charlene,
I am a 34 year old female and I too have PVC's. I seem to get them a few days before my period, during and up until I ovulate and then some. I definatly think its a hormonal thing.GOOD LUCK
There have been so many changes in your life, it is difficult to know which, if any, are responsible for the PVC recurrence. You could try stopping the birth control pills and use another method of contraception and see if it helps. Going back on the atenolol could also make you less likely to have PVCs, even if it does not completely eliminate them.
