What is a common physical symptom indicating the need to stop an exercise test?

The presence of signs of poor perfusion is a crucial indicator that an exercise test should be halted. Poor perfusion can manifest in various ways, such as significant changes in blood pressure, limited blood flow to the extremities, or neurological symptoms like dizziness or confusion. These signs suggest that the body's ability to circulate blood and oxygen effectively is compromised, which puts the individual at risk during physical exertion.

Recognizing these symptoms is essential to ensure safety during exercise testing, as they may indicate inadequate cardiovascular function or potential complications that could lead to more serious health issues. Monitoring for signs of poor perfusion is a standard practice in exercise testing protocols and is critical for making informed decisions about an individual's ability to continue physical activity safely.
