I had a follow-up appointment with a cardiologist today related to this
-- he was baffled as to why they even sent me to him: "I have a next step for: go home and play some soccer." His rationale: "You're a young guy, who has never experienced any chest pain. Your heart motion was completely normal during the stress test. You're out playing soccer every day. You broke the treadmill during the test. You have normal blood pressure. You do not have a family history of heart issues. When I put all of the pieces together, I struggle to see how your stress test could be called 'abnormal'."
