Implementation of luo-rudi phase 1 cardiac cell excitation model in FPGA
Dynamic simulation of complex cardiac excitation and conduction requires high computational time. Thus, the hardware techniques that can run in the real-time simulation was introduced. However, previously developed hardware simulation requires high power consumption and has a large physical size. Du...

Dynamic simulation of complex cardiac excitation and conduction requires high computational time. Thus, the hardware techniques that can run in the real-time simulation was introduced.
