The radial artery pressure signal preprocessing and feature recognition on left ventricular assist device / 中国医疗器械杂志

ABSTRACT

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.
