Adaptive Lifting Scheme for ECG QRS complexes detection and its FPGA implementation

For ECG QRS complexes detection, an Adaptive Lifting Scheme (ALS) has been developed and successfully implemented in Field Programmable Gate Array (FPGA). Realized under XUP Virtex-II Pro environment, the system consists of Top Configuration Module, Detection module and ALS module. Tested by the samples generated from the MIT-BIH ECG Database, its detection accuracy is higher than 99.681%, fulfilling ECG signal processing requirements. Comparing with the same algorithm realized with C codes under TI´s TMS320VC5509A DSP system, more than 20% of processing time is saved.
