While waiting for a cardiology clinic visit, how should I record the relationship between activity and chest discomfort?

Record what you were doing before each episode of discomfort, the intensity of the activity, the start and end times, the location, the sensation, whether it was accompanied by shortness of breath or dizziness, and how it changed after stopping the activity. Do not intentionally increase exercise intensity to test symptoms; if discomfort persists, clearly worsens, or is accompanied by severe symptoms, contact emergency services immediately.
