An electrocardiogram or ECG machine is a device used to monitor and record the electrical activity of the heart. Since each heartbeat produces an electrical impulse in the heart, the generated cardiac electrical potentials can be measured with sensors placed on the body at different locations. Abnormal electrical activity can indicate conditions such as heart attack, chest trauma, reduced blood flow to the heart, arrhythmia or heart deformities.

The demand for portable and accurate ECG monitoring has grown substantially. Despite the smaller size of these portable products, ECG devices still require precision filtering, high-performance processing power and integrated high-resolution graphics control that is separate from the main microcontroller core.
