连续监测数小时的ECG信号，结合活动状态，对于预防心血管疾病非常重要。传统的ECG霍尔特通常不便于携带，因为它有许多电极附接到胸部并且因为它很重。提出了一种可穿戴、低功耗的环境感知心电监护系统，该系统集成了智能手机内置的运动传感器和自行设计的心电传感器。可穿戴ECG传感器由完全集成的模拟前端（AFE）、商用微控制单元（MCU）、安全数字（SD）卡和蓝牙模块组成。由于采用AFE设计，整个传感器体积非常小，仅为58 × 50 × 10 mm，适合穿戴式监护应用，一轮心电采集的总功耗仅为12.5 mW。借助智能手机内置的运动传感器，该系统可以计算和识别用户的身体活动，从而为连续的心电图监测提供上下文感知信息。实验结果表明，该系统在提高心律失常的诊断准确率和识别最常见的异常心电图模式在不同的活动的性能。总之，我们提供了一个可穿戴的，准确的和节能的系统，用于长期和环境感知的ECG监测，而无需在动力传感器设计上增加任何额外成本，而是在广泛使用的智能手机的帮助下。
Continuously monitoring the ECG signals over hours combined with activity status is very important for preventing cardiovascular diseases. A traditional ECG holter is often inconvenient to carry because it has many electrodes attached to the chest and because it is heavy. This work proposes a wearable, low power context-aware ECG monitoring system integrated built-in kinetic sensors of the smartphone with a self-designed ECG sensor. The wearable ECG sensor is comprised of a fully integrated analog front-end (AFE), a commercial micro control unit (MCU), a secure digital (SD) card, and a Bluetooth module. The whole sensor is very small with a size of only 58 × 50 × 10 mm for wearable monitoring application due to the AFE design, and the total power dissipation in a full round of ECG acquisition is only 12.5 mW. With the help of built-in kinetic sensors of the smartphone, the proposed system can compute and recognize user’s physical activity, and thus provide context-aware information for the continuous ECG monitoring. The experimental results demonstrated the performance of proposed system in improving diagnosis accuracy for arrhythmias and identifying the most common abnormal ECG patterns in different activities. In conclusion, we provide a wearable, accurate and energy-efficient system for long-term and context-aware ECG monitoring without any extra cost on kinetic sensor design but with the help of the widespread smartphone.
