angina threshold
The exercise intensity level at which a patient begins to experience chest pain or discomfort.
Full Definition
The specific heart rate, workload, or rate of perceived exertion at which a cardiac patient first experiences anginal symptoms during exercise testing or training. This threshold is a critical safety parameter that determines exercise prescription limits and requires immediate attention during supervised sessions. Documentation of angina threshold helps establish safe exercise parameters and track patient progress over time.
Usage
Usage note: Distinguish from anaerobic threshold, which refers to metabolic rather than symptomatic limits.
In Context
- "The patient reached his angina threshold at 4.2 METs during the stress test." — Exercise test report
- "Exercise intensity must remain below the established angina threshold to ensure patient safety." — Treatment plan
