Keep an eye on it and let others know whats going on. Watch your recovery time. Have a plan. In the majority of these incidents you have to be seen when you are having the symptoms. As an athlete know that by the time you get in to see the doctor things may have already been stabilized. If so then only detailed blood tests will show changes. Doc in the Boxes all have EKG machines and are often closer and faster to get into than a regular ER.
When my wife was in her 50s she started getting out of breath doing simple things. Both of us being ex Army Medics and me a PA-C, and she a Nurse we always have an emergency treatment bag. On one of her incidents she popped open our Aid Bag and slammed a coupe of Nitro Tabs.... RATS... Symptoms were immediately relived... OK... On to the cardiologist...
