Definition: The term "electrocardiogram" refers to a test that measures the electrical activity of the heart. This test is commonly used in medical settings to diagnose and monitor various conditions, such as arrhythmias (abnormal heart rhythms) or cardiac arrest. The ECG is typically recorded by an electrocardiogram machine, which produces a series of alternating high-frequency beats on the skin, known as stfts. These beats are then analyzed using specialized software to create a visual representation of the
