Clarifying the Myths: 10 Common Misconceptions about ECG-EEG Tests

The truth behind these essential medical procedures.


Tests for electroencephalograms (EEGs) and cardiograms (ECGs) are essential diagnostic instruments that evaluate the brain's and heart's electrical activity, respectively. Even though these tests are essential for medical diagnosis, there are a lot of common misconceptions about them that can cause confusion and false information.

This article will debunk ten common misconceptions about ECG-EEG tests, shedding light on the accurate information behind these essential medical procedures.

1. Misconception: ECG and EEG are the Same Thing

A common misperception is that the Electrocardiogram (ECG) and Electroencephalogram (EEG) tests are equivalent or have the same function. Actually, several facets of the body's electrical activity are the subject of these tests. 

The heart's electrical activity is captured by an ECG, which also measures the heart's contraction intensity and regularity. Conversely, an EEG tracks the electrical activity in the brain and aids in diagnosing neurological diseases, epilepsy, and seizures.

2. Misconception: ECG-EEG Tests are Painful

There's a widespread misperception that Seer Medical's ecg-eeg test hurts. Neither test causes any pain and is non-invasive. Electrodes are applied to the skin during an ECG to record the electrical signals from the heart, and electrodes are placed on the head during an EEG to monitor brain activity. 

While placing the electrodes may cause some discomfort, the tests are usually painless and well-tolerated.

3. Misconception: ECG-EEG Tests are Only for the Elderly

Another myth is that only older people or those with pre-existing medical issues can undergo ECG-EEG testing. People of all ages—from newborns to adults—can be subjected to these examinations. While EEGs are frequently used to evaluate brain function in patients of various ages, including children and adolescents, ECGs may be carried out during normal check-ups.
