What is the term for the record of the heart's electrical activity?

The term for the record of the heart's electrical activity is an electrocardiogram. It captures the electrical impulses that coordinate each heartbeat. By placing small electrodes on the skin, the device detects these voltage changes and creates a waveform that shows the timing and strength of the heart's electrical activity. This helps identify normal rhythm as well as abnormalities such as arrhythmias or conduction problems. The other instruments measure different things: a sphygmomanometer records blood pressure, a stethoscope lets you listen to heart sounds, and a pulse oximeter checks oxygen saturation.
