A high-quality, low-energy, small-size system-on-chip (SoC) solution enabling ECG mobile applications

ECG is widely used to monitor and diagnose cardiac conditions, but remains expensive and complex - limiting its reach to within the medical field. In this paper, we introduce the CardioChip: a single-channel, low-power, small-size ECG application-specific integrated circuit (ASIC) designed for personal mobile applications. We first show that the signal from the CardioChip Starter Kit, a wireless handheld device used to collect ECG from the index fingers, is comparable to a research-grade gel-based ECG (correlation = 98.6%). We next present a CardioChip-based R-peak detection algorithm that is able to reach a median sensitivity of greater than 0.98, and a median precision of 1. Lastly, we present a CardioChip-based respiratory rate algorithm and show that it is more accurate than a pneumography-based respiration device.
