摘要
Nowadays,numerouscommercialelectrocardiographs(ECG)have500Hzoutputsamplingrate,i.e.,2mscorrespondingsamplinginterval.Medicalworkerswhohavenobackgroundofsignalprocessingmayworryaboutwhethersuchlow500Hzoutputsamplingratedatacouldsupporthigh-precisionestimationofelectrocardiogramparametersbybeingup-sampled.Withintentiontoclarifytheproblemtothemedicalworkers,thispapertakessomesimulatingexperimenttoillustrateit.TheexperimentchosetheRRintervalandRpeakamplitudeasrepresentativeparameterstobeestimated.Theobtainedresultswereasfollows:forRRintervalparameter,itsestimationerrorcanbeloweredtobelow0.3msbyup-sampling;forRpeakamplitude,itsestimationerrorcanbereducedtobelow2.0μVbyup-sampling.ItisbelievedthatotherECGparameterestimationcanalsobeimprovedsimilarlybyup-sampling500Hzdata.
