What are the types of cardiac stress tests?

The types of cardiac stress tests include:

  • Electrocardiogram: The sticky patches on your chest send signals to a machine that measures the electrical activity of your heart.
  • Stress echo: In this case, before you exercise a technician will move a device called a transducer over your chest. The transducer sends sound waves that bounce back to create images of your heart. After you exercise, the technician will use the transducer again, to take images while your heart is beating hard.
  • Nuclear imaging: A radioactive "tracer" will be injected through the IV. A special camera will record where the tracer collects in your heart. This shows the parts of your heart that have good blood flow.

The types of cardiac stress tests include exercise tests and chemical tests.
