尽管医学发展迅速，心血管疾病仍然是世界上的头号杀手。在法国，每年有5万多人死于心律失常。高风险猝死患者的识别仍然是一个挑战。为了检测心律失常，目前霍尔特一般是记录24 ~ 72 h内的1~3导联心电图信号。然而，由于其外形因素（不方便用户）和成本，霍尔特的使用在人群中受到限制。本文提出了一种集成的单芯片可穿戴式霍尔特，即SoC-霍尔特，它能够记录1~4导联心电图。该单芯片SoC Holter是基于适当的算法架构设计方法。为了最大限度地降低能耗，CMOS技术（0.35µm）用于第一次实现和测试的原型。该系统具有信号调理、放大、滤波、模数转换和纳米控制等功能。低通滤波器由电流分配电路、负反馈电路和共模反馈电路组成。模拟电路的实现，测试和验证。对数字模块进行了仿真、实现和测试。因此，研制一种集成化、低成本、用户友好的单芯片霍尔特是可行的。因此，可以监测大量的高风险人群，例如重度吸烟者和肥胖者。该SoC Holter在器件工作时的功耗小于10 mW。
In spite of the rapid development of medicine, cardiovascular diseases are still the number one killer in the world. In France every year more than 50,000 people die suddenly due cardiac arrhythmias. Identification of high risk sudden death patient is still a challenge. To detect the cardiac arrhythmias, currently Holter is generally used to record 1~3 leads ECG (electrocardiogram) signals during 24h to 72h. However the use of Holter is limited among the population due to its form factor (not user-friendly) and cost. In this paper, we propose an integrated single chip wearable Holter named SoC-Holter, which enables to record 1~4 leads ECG. This single chip SoC-Holter is relied on adequation algorithm architecture design methodology. To minimize energy consumption, CMOS technology (0.35µm) is used to prototype the first implementation and test. The SoC-Holter has the following functions: signal conditioner and preamplifier, amplifier and filters, analog to digital converter, and Nano-controller. The low pass filter is composed of current division, degeneration and common-mode feedback circuits added to fulfill the required performance. The analog circuits are implemented, tested and validated. The digital bloc is simulated, implemented and tested. It seems that an integrated, low cost, and user-friendly single chip Holter is feasible. Consequently large number of high risk populations such as heavy smoker and obese may be monitored. This SoC-Holter consumes less than 10mW while the device is operating.
