Abstract

The paper presents the implementation of a low cost, small size portable measuring system based on a personal digital assistant (PDA) for heart rate and blood pressure variability evaluation. The signals obtained from electrocardiogram (ECG) electrodes and non-invasive arterial blood pressure (BP) sensors are pre-processed using a set of filters for noise reduction and acquired using two analogue channels of a data acquisition board. A distributed processing of ECG and BP acquired data is performed. In the most interesting configuration, the PDA does the data acquisition, display and data communication while the main part of data processing is performed in a host laptop PC. Data communication is performed under an ad-hoc wireless network (802.11g).
