The majority of people have PVC's and never notice them. If you are experiencing anxiety, it will certainly make the PVC's worse; however if this is beginning to control you life do see you Dr. for a medical screening exam to make sure you do not have a medical condition that is causing the PVC's.
Try not to use Dr. Google to much as that can send your anxiety into the high range. Also remember you may be having PAC's and not PVC's.
