An electrocardiogram|heart tracing|ECG is a procedure that measures the electrical activity of your heart. A resting electrocardiogram and electrocardiograph ECG| EKG at rest|ECG during a resting state involves placing small sensors on your chest. These patches send signals to a machine that generates a visual representation of your heart's rhythm.

An electrocardiogram at rest is a fundamental tool used to establish a baseline for an individual's heart function. This non-invasive procedure monitors the electrical activity of the myocardium as it contracts, producing a visual representation known as an electrocardiographic tracing. During a resting ECG, the patient typically lies down while el
