At the moment of a skipped heart beat I feel this horrible electrical pain, sort of like the esophagos and abdomen just go into a painful spasm.. Is this just a reflex from the excitement of the skipped heart beat/PVC.. I m not terribly worried about it because I ve been getting these spasms on and off for many years and nothing has really happened to me other than being terrified of them.. I suffer from thousands of PVC s a day probably from anxiety.. But these painful electrical spasms tend to rear their ugly head when I m overwhelmed with worry and stress..
