electrocardiogram (ECG) response

An electrocardiogram (ECG) is a test that measures the electrical activity of your heart. When your heart beats, electrical signals travel through it, triggering contractions that pump blood. An ECG uses small sensors called electrodes placed on your skin to detect these signals and record them as waves on paper or a computer. This helps doctors assess your heart’s rhythm, identify irregularities, and detect issues like blockages or damage. In essence, an ECG provides a snapshot of the heart's electrical function, offering valuable information about its health and performance.
