Hellinall. Haven't been on here in a while. I'm having my first stress test done wednWedne w/o contrast. I had a ST Jude dual lead pacer put in October 9 2017 for 2nd degree heart block and 34 years old. No medical history besides the pacer and spinal stenosis. Since I had the pacer put in every now and then I would get chest tightness and feel short of breath. Pulse always normal when it happened at 80. So I would call and all doctors say is ohh it's anxiety. They said the stress test is tomconfto I have nothing wrong. I guess though I'm not sure what to believe anymore. Also I am not in as great shape so how much should I worry about the stress test? Thanks all . Your posts have helped me move on from the incident as I call it. I quit going to ER for every ping and pang anyway.
