An electrocardiogram (ECG) or EKG, performed at rest is a non-invasive procedure that measures the electrical activity of the heart. It involves placing small adhesive electrodes on the chest, arms, and legs to detect the tiny heart signals produced by the heartbeat. These signals are then amplified and recorded on a graph paper or digital display.

An electrocardiogram at rest is a fundamental tool used to establish a reference point for an individual's heart function. This non-invasive procedure records the electrical activity of the cardiac muscle as it beats, producing a visual representation known as an electrocardiographic tracing. During a resting ECG, the patient typically lies down wh
