An echocardiogram (echo) is a graphic outline of the heart’s movement. During an echo test, ultrasound (high-frequency sound waves) from a hand-held wand placed on your chest provides pictures of the heart’s valves and chambers and helps the sonographer evaluate the pumping action of the heart.
You should not consume alcohol, caffeine or tobacco (or other source of nicotine) for 24 hours before the test.
No special preparation is needed before having this procedure.
