What is the standard abbreviation for the test that records the heart's electrical activity?

• A. EEG
• B. ECG
• C. ECHO
• D. EMG

Answer: (B)

Recording the heart’s electrical activity is done with an electrocardiogram. Electrodes placed on the skin pick up the heart’s electrical impulses as it beats and translate them into a tracing that shows rhythm, rate, and conduction patterns. This electrical signal pattern helps detect issues like arrhythmias, ischemia, or conduction abnormalities. The standard abbreviation for this test is ECG, short for electrocardiogram, and it is the term used in most medical references. In contrast, EEG measures brain activity, EMG measures muscle electrical activity, and ECHO (echocardiography) uses ultrasound to visualize heart structure and movement rather than electrical signals.
