What To Expect During Echocardiography. Echocardiography (echo) is painless; the test usually takes less than an hour to do. For some types of echo, your doctor will need to inject saline or a special dye into one of your veins. The substance makes your heart show up more clearly on the echo pictures. The dye used for echo is different from the dye used during angiography (a test used to examine the body's blood vessels). For most types of echo, you will remove your clothing from the waist up.
