Resting ECGs are recommended if there is a history of premature heart disease in your family, if you have risk factors for heart disease or if other tests or symptoms indicate one is needed. Stress tests record the heart's electrical activity during exercise. The patient steps onto a treadmill and begins to walk. The heart's electrical activity is then observed on a screen and recorded while a patient exercises. Like resting ECGs, stress tests are recommended if there is a family history of premature heart disease, if risk factors are present or if other tests or symptoms indicate one is needed.
Echocardiograms provide information about the heart's structure.
A microphone-shaped instrument called a transducer is placed on the chest. It sends ultrasound waves that reflect off the surface of the heart, forming a moving image seen on a screen. An echocardiogram is recommended when a doctor suspects a problem with the heart or its pumping ability. Patients with very early signs of heart disease can work with a doctor to reduce their risk. The test is simple and painless and takes only a few minutes.
