Shortness of breath resulting in being unable to exercise ( 2x weekly one mile swimmer) could not complete 5 laps! Also walking any distance, normal housework ?all an extreme effort. Just did not feel ?right? or like myself. Went to urgent care on November 8th, sent to ER. After a whole day of EKG, chest x-ray, bloodwork to check heart enzymes, I was released and told to go to a cardiologist within 72 hours.
