Echocardiogram is also known as an ultrasound scan of the heart, an echo, or sonar of the heart. EKG is also known as an ECG, a 12 lead EKG, or an electrocardiogram.

What is the difference between ECG and echo?

an echocardiogram. Although they both monitor the heart, EKGs and echocardiograms are two different tests. An EKG looks for abnormalities in the heart's electrical impulses using electrodes. An echocardiogram looks for irregularities in the heart's structure using an ultrasound.

Is Echo necessary if ECG is normal?

If your electrocardiogram is normal, you may not need any other tests. If the results show an abnormality with your heart, you may need another ECG or other diagnostic tests, such as an echocardiogram. Treatment depends on what's causing your signs and symptoms.
