I also have had pain down my arm tingling and pain up my jaw. I had heart tests but nothing showed up except slight mitral valve. All my dads male relatives have died from sudden death including my cousin who died 5 years ago from this. With neurocardiogenic syncope I know I am at greater risk for this. My dad has a pacemaker and then he got a defibrilator he has congestive heart failure with only 20% output in his heart and now is having pulmonary problems. I have more symptoms of congestive heart failure then my dad. His chf DR. said he wouldn't touch my case with a ten foot pole. I get so discouraged especially when my insurance wont pay for me to see Dr. Khruna because he is not in my network. My cardiologist and neurologist both wrote in and they wont approve it. I saw him 2xs and loved him. He now wants to do tests but if anything would happen or show up during ,my insurance wont pay.
