Circuits, Systems, and Technologies for Detecting the Onset of Sudden Cardiac Death Through EKG Analysis

This article discusses the circuits, systems, and technologies that can be put together to design an electronic-vest that is capable of recognizing a cardiac event and alerting emergency services personnel. The discussion includes state-of-the-art in electronic textiles, analog/radio-frequency circuits, flexible antenna design, sensor design, signal processing, and fault tolerant and dynamic reconfiguration of sensors and processing components. Preliminary design, analysis, and prototyping issues are discussed to demonstrate the feasibility of implementing the technologies.
