No, I've not had a heart cauterization but had a heart ct scan this year. I was told that my arteries were good. I've had stress test and nuclear stress test and all were good. I do not have AFib but I do get skipped beats and I've been told it's an electric impulse issue but not serious. I have a large hiatal hernia that is possibly causing some of my symptoms; pulmonologist believes it might be pressing on my lungs. I believe it is the cause of some shortness of breath but I've had it for a long time and just recently my symptoms of fatigue and inability to walk any distance or climb steps of any height have gotten much worse. If I knew that the hernia was the reason for my inability to function, I would schedule repair surgery as soon as possible. It is not an easy surgery with recuperation taking a while along with possible complications. I've also been warned that a major concern is the hernia returning or tearing loose even before I leave the hospital. My fear is that I will go through this surgery and my condition will not be better. As I stated, I also have asthma and I read some concerns about being given metropoplol with asthma drugs. Thanks for all your suggestions.
