I have exprienced strange electical like spasms accross my chest and back, down both arms and sometimes up my neck.They last only a second to 30 seconds and are now and then. One day I had 5 in a row. Another day I expeienced them all day long at least every half hour. I have had an EKG and a cardiac nuclear image and stress tests which said the blood flow was normal. The spasms stop me in my tracks. My blood pressure is good,cholesterol is 180. I also have made another app with cardiologist.
