Description of Test ECG electrodes will be attached to your
chest. The electrodes are small, sticky patches with wires. Your
resting blood pressure and ECG readings will be taken. The
cardiac stress test is done on a treadmill or a stationary bike.
You will slowly start walking or riding. At regular intervals,
the speed and elevation will be increased. Your ECG, blood
pressure, heart rate, and symptoms will be closely monitored.
The test may be stopped early if you feel extremely tired, get
chest pain, have trouble breathing, or if you have any symptoms
that suggest heart problems. Significant changes in the ECG will
also stop the test. After exercise is complete, your blood
pressure, heart rate, and ECG will be monitored until levels
return to normal. Your doctor may also order a blood flow
imaging exam. This is called a nuclear stress test. A small
amount of radioactive chemical will be injected into a vein when
you are exercising at your peak. Scans will be taken while you
lie in different positions under
