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)

  • Determine if there is adequate blood flow to your heart during increasing levels of activity
