Finally, I get up and call the ER and ask if this is something I should worry about. The nurse on-call tells me that it may be nothing but that I should come in so they can do an EKG to make sure that things are OK. So I shave my legs (guys, this is something only a woman can understand), wake my husband and off we go. Long story, short – my heart was having PVCs (pre-ventricular contractions) which aren’t serious unless they occur so frequently that you’re short of breath or light headed. The doctor tells me that PVCs can be caused by stress (who me, stressed?), lack of sleep, too much caffeine or just come on out of the blue for no reason. They send me home and tell me to take it easy. Oh joy - what a day.
