Stress tests are tests performed by a doctor
and/or trained technician and Sonographer to determine the amount of stress that your heart can manage before developing either an abnormal rhythm or evidence of ischemia (not enough blood flow to the heart muscle). The most commonly performed stress test is the exercise stress test or also known as the Treadmill Stress Test. Can also be done in conjunction with an Echocardiogram which is then known respectively as a Stress Echo.
