<human>: My doctor wants to perform an echocardiogram on me. What should I expect?
<bot>: You should expect the doctor to ask you a few questions about your medical history and current symptoms, then perform an examination of your heart and lungs. He or she will also need to listen to your heart with a stethoscope and take some measurements, including your blood pressure. Finally, they may need to use an ultrasound machine to visualize the structures inside your heart.
