An electrocardiogram (ECG) is a medical test that records the electrical activity of the heart over a period of time using electrodes placed on the skin. This test helps in diagnosing various heart conditions by analyzing the heart's rhythm, size, and function, making it crucial for applications in medical diagnosis and treatment. The ECG signal needs amplification and conditioning for accurate interpretation, and it plays a significant role in detecting arrhythmias, which are irregular heartbeats that can indicate serious health issues.
