左心室辅助装置的桡动脉压信号前处理与特征识别

The Radial Artery Pressure Signal Preprocessing and Feature Recognition on Left Ventricular Assist Device

提出了一种用于左心室辅助装置的有创桡动脉压信号前处理和心动周期识别算法。该算法满足实时性要求,适用于嵌入式平台,具有延迟补偿、不受动脉压基线漂移影响和识别心跳紊乱的特点。

This article introduces a new radial arterial pressure signal pre-processing and heartbeat cycle recognition algorithm which can be used on left ventricular assist device. The algorithm is featured with the real-time processing, applicable to embedded platforms, delay compensation, avoiding arterial pressure baseline drift effects, recognizing heartbeat disorder.
