Cardiac Doppler is a doppler test for your heart. Similar to an echocardiogram, a Doppler ultrasound (or Doppler echocardiography) is a test in which very high frequency sound waves are bounced off your heart and blood vessels. It may be recommended for patients with atherosclerosis or coronary artery disease.
It is used to assess blood flow through the coronary arteries (the blood vessels supplying the heart), the carotid artery (the main artery in the neck), the major arteries in the arms and legs, or in the heart itself (echocardiography).
Cardiac Doppler is a type of Color Doppler ultrasound.
