Hello. I am Karen, age 68, diagnosed with A-fib about four years ago and just started having PVCs in the last month or two. I have commented on other threads but not this one. I have a holter monitor until tomorrow and then will get results in a week or so. I am a little scared because I seem to be having PVCs all he time now whereas I only have A-fib a couple of times a week. The PVCs make me feel very weak, out of breath, and generally uncomfortable with adrenalin rushes, dizziness, sometimes slight nausea. I passed out for a second and fell doing yoga yesterday. I am also underdoing cancer treatment (lucky me) which might be adding to my discomfort.
