A stress echocardiogram is a medical test that combines an ultrasound of the heart with physical exercise or medication to assess how well the heart functions under stress. During the test, a patient may walk on a treadmill or receive a drug that simulates exercise, while images of the heart are taken using ultrasound technology. This helps doctors evaluate blood flow to the heart muscle and identify any potential issues. The test is often used to diagnose conditions such as coronary artery disease or to assess the effectiveness of treatments. It is non-invasive and typically takes about an hour to complete, providing valuable information about heart health and function.
