Dear Rodrigo, Your approach seems correct. Indeed, this is the approach implemented by the LoadBeatRR. That's why i find strange that you don't get good results with LoadBeatRR. In any case, you can use your approach, if that's working for you. Kind regards |

Constantino, really appreciate your help and your time. Thanks for great library. I have made those tests. Even doing filters I think that the values of HR are not corrects. However, I made another approach: I produced a new ASCII file (attached), starting with '0' and following by a Sum of my R-R Intervals, the same intervals of old file 'rr.csv''. I think I produced similar data standard of 'example.beats' file from RHRV site tutorials. Then I loaded this new file with function LoadBeatAscii(). I had note that this approach gives me near (or even equals) "hrv.data$Beat$niHR" values that I have read from Polar. And values form "hrv.data$Beat$RR" are the same of 'rr.csv'. I think this approach is correct to generate file for RHRV load. Am I right? Best! |

Dear Rodrigo, I am getting erros due to the fact that there are a couple of zeros in your file (rows 829 and 830). After deleting them, I am also getting very high HRs due to the fact that rows 631 and 632 have values 284 (.284 seconds). You can remove them using FilterNIHR(). Hope this helps Kind regards |

Hi, I am using LoadBeatRR function to read my "rr.csv" file with scale="0.001": "hrv.data = LoadBeatRR(hrv.data, "rr.csv", scale = 0.001, RecordPath = ".")" However, after Load function, I saw that "hrv.data$Beat$time" is filled, and when I build NIHR with function: "hrv.data = BuildNIHR(hrv.data)" The field "hrv.data$Beat$niHR" and "hrv.data$Beat$rr" is filled with strange values, like 200+ bpm in HR, e.g. And I know the values from HR to compare with. 1) The "rr.csv" file is attached. 2) This file is generated by another app, with Polar H7 RR intervals readed directly from sensor and applied calc: (rr / 1024.0) * 1000.0, accord docs from Polar. In short, I would like to use RHRV with RR intervals file because I already have it. Can you please provide some help? Thanks |
