Last night I had episodes (very short 5 seconds or less) it felt like an electric shock in my upper left side of my chest.  I also had one episode today at work in the late morning.  I just had blood work down and cholestrol was 169, triclycerides 75, glucose 94 etcccc
Hello and welcome to Chat Doctor forum. These electric shock like sensation is due to nerve irritation. It has nothing to do with cardiac symptoms.
