While having my blood pressure checked last time I was at the doctors, she noticed my heart s skipping a beat every 6 or 7 beats, so they did an EKG right there; apparently I ve (suddenly, it seems) developed PVCs. I m 60, but in good health; I jog, eat right, have no history of any heart stuff. She said it could be problematic, and we re watching it; it s just something I d never heard of. anything I should be doing differently in my life, or should I just not worry about it?
