ECG-multichannel frontend for quick stimulus response based on FPGA with implemented real-time, online QRS detection algorithm

Nowadays, economic globalisation is one of the strongest influences in the field of bioelectronics. Due to this, a solid symbiosis is increasing between research and economics. Especially small and medium-sized businesses (SMBs) expect to become and remain a part of this symbiosis. The sector of medical biosignal processing demands effective, compact, low cost and low energy embedded systems that are capable to adapt to new conditions on the market. In this paper, a system solution for SMBs is described that comes with the above-mentioned factors. For this reason, an easily adaptable multichannel frontend as daughterboard combined with an open source, online, realtime QRS detection algorithm based on Field Programmable Gate Array (FPGA) was developed.
