Is echocardiogram and electrocariogram the same?

No, an echocardiogram and an electrocardiogram (ECG or EKG) are not the same. An echocardiogram uses ultrasound waves to create images of the heart's structure and function, while an electrocardiogram measures the electrical activity of the heart through electrodes placed on the skin. Both tests are important for diagnosing heart conditions but serve different purposes.
