Which test is NOT routinely used for diagnosing myocardial infarction?

Electroencephalogram (EEG) is a test that measures electrical activity in the brain and is primarily used for diagnosing conditions related to brain function, such as seizures, epilepsy, and other neurological disorders. It does not provide information about the heart or its functioning, making it unsuitable for diagnosing myocardial infarction (heart attack).

In contrast, a CT scan can be used to visualize heart conditions and assess the presence of coronary artery disease, whereas an echocardiogram helps evaluate heart structure and function by using ultrasound. A stress test assesses how the heart performs under physical exertion, which can reveal issues related to myocardial ischemia. All of these tests are related to cardiac assessment, highlighting the differences in their applications compared to an EEG.
