There are different types of heart diagnostic tests to check the health of blood vessels and heart function, the two most commonly used of which are heart exercise test and stress echocardiography. Although these two methods have similarities, they differ in the type of investigation, accuracy, equipment and even application for different patients. The difference between heart exercise test and stress echo Stress echo is actually a combination of cardiac exercise test and echocardiogram. That is, the patient may exercise on a treadmill, and after that, the doctor will take detailed pictures of the heart with an echocardiogram to see if an area of ​​the heart is not pumping properly or not receiving enough blood flow. If the patient is not able to exercise, stress echo is done in the form of medication: drugs such as dobutamine or adenosine are injected into the body to stimulate the heart, then the function of the heart is checked with echo. The difference between exercise test and echocardiography in diagnosis Cardiac exercise testing mostly assesses the heart's electrical activity. The main items include: - **Heartbeat and its rhythm**: Checks how the heart beats during exercise and whether its rhythm is regular or disturbed. - **Reaction of the heart to stress and physical activity**: The tolerance of the heart and changes in blood pressure and heart rate during exercise are checked. - **Cardiac ischemia**: detection of areas of the heart that may not receive enough blood (vascular blockage). In addition to examining the electrical activity, stress echo measures the structure and function of the heart with visual details: - **Heart muscle function**: Checks whether all parts of the heart are contracting and pumping blood properly. - **Function of heart valves**: It is observed that the valves open and close properly. - **Blood flow and heart pumping**: The amount of blood supply to different parts of the heart and its changes are checked under conditions of stress or after medication. Simply put: exercise testing focuses more on the electrical activity of the heart, but stress echo is more accurate and visual and shows the actual function of muscles and valves. ### comparison table of heart exercise test and echo stress The exercise test is a basic test with an ECG, but the stress echo is a more advanced and more imaging form of it that is combined with echocardiography. Echo is better or exercise test? This is a common question of patients. The answer depends on individual circumstances: - If the person has the ability to exercise and needs an initial test, the exercise test can be sufficient. - If a more accurate diagnosis is required or the patient has limited mobility, stress echo will be a better option. summary - **Heart exercise test**: a basic test with ECG recording during activity. - **Stress Echo**: a more advanced version and an image that provides higher accuracy in diagnosing heart problems with the help of echocardiography. In simple words: **Exercise test is the most basic method; But stress echo is a combination of exercise test and heart echo and shows more detailed details of heart function.**
