In this draft, our purpose is to construct a wearable multi-lead electrocardiogram (ECG) recorder with dry metal electrodes. In general, such as arrhythmia, myocardial ischemia or other heart-related symptoms, using one lead ECG measurements is difficult to accurately diagnose, three-lead ECG should be measured at least. In order to offer sufficient identification information, our scheme is a three-lead ECG solution with recording mode and real-time display mode. Besides, our proposition using dry metal electrodes provide a comfortable sensation, less skin-irritating, easy clean surfaces, reusable capability, and more durability. Due to these advantages, dry metal electrodes are suitable to integrate with underwear. The whole system includes an embedded microcontroller, a memory card interface, analog front-end circuits, user interface devices, power regulators, and so on. All elements integrate within a 5.8cm x 6.8cm four-layer printed circuit board (PCB) to meet the wearable request.
