Systolic blood pressure was estimated every 30s using PPG and ECG in patients undergoing surgery.Nine features capturing information embedded in waveforms and derivatives were extracted from PPG and ECG signals.Dynamic feature selection was proposed based on feature robustness and the principle of ...
ECG信号虽然精准并且信息丰富,但是由于测量ECG信号常常要在身体多个部位连接传感器电极,在临床医疗领域外并没有得到太多的应用。现在各种可穿戴设备采用的都是光电容积脉搏波描记法(photoplethysmographic,PPG)来简单测量心率。 采用PPG原理的光学心率传感器往往有一个发光元件,测量心率时LED光射向皮肤,透过皮肤组织反射回...
