What does ECG stand for?

Explanation:
ECG stands for electrocardiogram, a test that records the heart’s electrical activity over time. The name reflects its function: electro- refers to electrical signals, cardio- to the heart, and -gram to a recording. This test helps assess heart rhythm and conduction, and can reveal arrhythmias or other cardiac issues. It’s not an echocardiogram, which uses ultrasound to visualize heart structure and pumping function; nor an electroencephalogram, which measures brain activity; nor electromyography, which evaluates nerve and muscle function.
