Originaly, it had been a dull pain in her strunum when she would walk...off & on. But last night after I left, she got out of recliner & walked up a few steps to the kitchen & then, she was experiencing the classic symptom. Left arm pain, jaw pain & the such. When I saw her later, & when she was feeling better, that she told me the ems told her that they could take her to the E.R. or she could drive herself since the ekg wasn't really showing much. It wasn't until today when the cardiologist was involved did we really realize what was going on.
