ECG vs. EKG vs. EEG

An ECG is an acronym for echocardiogram, EKG is acronym for electrocardiogram, and EEG is an acronym for electroencephalogram.

An ECG  is a more advanced testing procedure in comparison to the EKG. The echocardiogram uses ultrasound, or echoing high-frequency sound waves, to create a visual image of your heart. This helps doctors view the internal structure of your heart and how well blood is able to flow through it. Doctors can also get an accurate read on the size and shape of your heart, as well as the level of heart valve function. Echocardiograms are typically used to diagnosis blood clots, infections, and can be used to detect previous heart attacks. By indicating the velocity of blood flow as it leaves the heart, an echocardiogram can indicate whether the heart is pumping efficiently. An ECG can be performed with an external tranducer moved over the heart area or a transesophageal ECG where a thin, flexible tube is inserted into your mouth and down your esophagus.

An EKG can be an effective diagnostic tool for measuring the electrical efficiency of your heart. A healthy heart beats at a certain rhythm. An EKG displays the patterns of your heart as it beats, to determine abnormalities in heart rhythm. It can detect changes in the thickness of the heart walls, or potential damage to the heart muscle and tissue. It is performed by attaching various leads to your chest area.

An EEG is a test that also measures electrical activity, but in the brain and nerves. The electrical signals in your brain, or brain waves, are recorded in peaks and valleys on a graph. It can help determine a seizure, epilepsy, a tumor, or a stroke. EEG is also used to detect head injuries, sleep disorders, dementia, or Alzheimer’s Disease, and more. It is performed using metal discs called electrodes stuck to your scalp.
