Final answer:
The Electro-oculargraph (EOG) is an eye-tracking technology used to record eye movements through the detection of electrical potentials and should not be confused with the electrocardiogram (ECG) or echocardiography (ECHO), which are related to heart diagnostics.
Step-by-step explanation:
What is Electro-Oculargraph (EOG)?
The Electro-oculargraph (EOG) is a type of eye-tracking technology used to measure the electrical potential of the human eye in order to track its movement. This technology should not be confused with devices related to the heart, such as the electrocardiogram (ECG) or echocardiography (ECHO). The ECG is used for recording the electrical activity of the heart and diagnosing irregular heart function by placing electrodes on the body, while ECHO uses ultrasound to obtain an image of the heart's structure and function.
An EOG involves placing electrodes around the eyes to detect eye movement, which is useful for various types of ophthalmological and neurological assessments. It is entirely different from an ECG, which is a critical and widely used diagnostic tool in cardiology that monitors heart electrical activity using surface electrodes.
