Exercise Stress Testing


The exercise stress test — also called treadmill test, is used to provide information about how the heart responds to exertion. It usually involves walking on a treadmill at increasing levels of difficulty, while your electrocardiogram, heart rate, and blood pressure are monitored.

Indications (Why do I need a Stress test)
