I saw the cardiologist this afternoon. He says I am having PVCs (premature ventricular contractions). They might not be anything much, but also might indicate some underlying issue. So, I need to do an exercise nuclear stress test and a 48-hour holter monitor. Those tests are scheduled for next Tuesday, because it takes 3 days to get the necessary pre-certification from the insurance company. After that? I cannot get an appointment to have a doctor follow up with an interpretation of the testing until June 4.
