What does ECG stand for?

Explanation:
ECG stands for Electrocardiogram, a recording of the heart’s electrical activity. The name breaks down into Electro- (electric), cardio- (heart), -gram (record). The test uses skin electrodes to pick up the electrical signals that coordinate heartbeats, producing a tracing with waves named P, QRS, and T that reflect different parts of the cardiac cycle. This helps detect rhythm problems, conduction issues, or heart muscle damage. The other terms refer to different tests: Echoencephalogram images the brain using ultrasound; Electromyogram measures muscle electrical activity; Electroencephalogram records brain electrical activity. Since the heart’s electrical activity is what ECG is meant to capture, Electrocardiogram is the correct expansion.
