Abstract:
This work presents the design and the implementation of a two-channels recording system and its adaptation to a FPGA-based acquisition system. The recorded signals are Electrocardiogram (ECG) and Intraventricular Pressure (IVP). Elements and circuits needed to incorporate the newly developed recording system to a previously developed FPGA-based Conductance Catheter System SCC are also presented. The result is a fully integrated system, in which the evaluation of each channel is carried out. ECG amplifier is evaluated by means of frequency response and common mode rejection ratio. Filter frequency response and two calibration methods, over 0-150 mmHg and 150-300 mmHg ranges, are used to evaluate PIV channel. Finally analogical to digital conversion and communication between two-channels recording system and FPGA-based acquisition system are tested. Satisfactory results are obtained.
