Which of the following is not an indication for electroencephalography (EEG)?

Electroencephalography (EEG) is a diagnostic tool that records electrical activity in the brain and is primarily used to evaluate neurological conditions. It is particularly effective in diagnosing and managing epilepsy and seizures, as it can capture seizure activity and other brain wave abnormalities. Additionally, EEG is useful in assessing sleep disorders by measuring brain activity during different sleep stages, helping to identify sleep-related issues.

Brain tumors can also be an indication for an EEG, as these tumors may disrupt normal brain function and electrical activity, potentially leading to seizures or other neurological symptoms.

In contrast, cardiac anomalies pertain to issues related to the heart and its function, which are outside the scope of EEG. While the brain and heart are both vital organs, their assessments require different diagnostic approaches. Cardiac conditions are evaluated through techniques such as electrocardiograms (ECG or EKG), imaging studies, and other cardiac-specific tests. Therefore, the relationship between cardiac anomalies and EEG is not relevant, making it the correct answer in this context.
