I was getting an ekg because I am going to have a hernia surgery. The ekg showed up as abnormal which I suspected it would because my heart skips a beat every now and then which it has been doing for about 8 years off and on. The doctor wrote on my ekg sinus rhythm vertical axis RBBB marked right-precordial repolarization distrubance secondary to RBB I am just trying to understand what each of these things means. I don t have health insurance right now so I did not want to do any further tests unless absolutely necessary. I have a good wind and do well in aerobic exercises so I haven t been worried. Since my hernia I haven t exercised as much and have been more stressed and I think that this is why the symptoms are stronger now.
