摘要: Several devices and measurement approaches have recently been developed to perform ballistocardiogram (BCG) seismocardiogram (SCG) measurements. The development of a wireless acquisition system (hardware software), incorporating novel high-resolution micro-electro-mechanical (MEMS) accelerometer for SCG BCG signals data treatment is presented in this paper. A small accelerometer, with sensitivity up 0.164 µs/µg noise density below 6.5 µg/ Hz used applications. also incorporates electrocardiogram (ECG) acquisition, the software enables real-time visualization ECG (sensor positioned on chest). It then calculates metrics related cardiac performance as well correlation from previously performed sessions echocardiogram (ECHO) parameters. preliminarily clinical study over 22 subjects (including healthy cardiovascular patients) was test capability system. Data between exams performed. high resolution MEMS provides better signal wave recognition, enabling more consistent diagnostic technique analysis.
