Electrocardiography (ECG) is a diagnostic procedure that involves the recording of the heart's electrical activity through the placement of electrodes on the skin. These electrodes detect minute electrical variations on the skin's surface that result from the depolarization and repolarization patterns of the heart muscles during each heartbeat. ECG is a widely utilized cardiology test, providing valuable insights into the heart's function.

The Allied Meditec E400 Series ECG machines present a range of options to meet diverse requirements. Within this series, three different models are available: the E402, E417, and E427. Each model is designed to cater to specific needs, ensuring optimal performance and usability.
