An Echocardiogram (Echo) is a non-invasive test that uses ultrasound waves to create detailed images of the heart’s structure and function. It helps doctors assess heart health by visualizing the heart chambers, valves, and blood flow, making it essential for diagnosing heart diseases and monitoring heart function. Patients should opt for an echocardiogram when recommended by their doctor to evaluate symptoms like shortness of breath, chest pain, or irregular heartbeats.
