# Hello

This is a code highlithing test:

function myFunction(p1, p2) { return p1 * p2; // The function returns the product of p1 and p2 }

## ECG Module Metrics

The autogenerated table below shows the metrics calculated by the PhysioData Toolbox's ECG module.

Variable Name: | Unit: | Description: |
---|---|---|

HR_mean | BPM | Mean of the continuous Heart Rate, as interpolated from the accepted IBI data points. |

R_peakCount | count | Count of accepted R-peaks inside current epoch. |

IBI_mean | s | Arithmetic mean of the accepted discrete IBIs. IBI values are defined as: IBI(n) = Rt(n)-Rt(n-1), and are timestamped using: IBIt(n) = Rt(n). |

IBI_weighted_mean | s | Self-weighted mean of the accepted discrete IBIs; i.e., sum(IBIs.^2)/sum(IBIs) |

IBI_min | s | Min value of the accepted discrete IBI data points |

IBI_max | s | Max value of the accepted discrete IBI data points |

IBI_std | s | Standard Deviation of the accepted discrete IBI data points (SD normalized by (N-1) , where N is the sample size) |

IBI_count | count | Count of accepted IBI data points inside current epoch. |

IBI_coverage | % | The percentage-wise IBI coverage of the epoch; i.e., 100*(sum of the IBIs)/(Epoch Duration). |

HRV_rmssd | ms | The Root Mean Squared of the Differences between Successive IBIs (nonadjacent IBIs disregarded). |

HRV_ssdCount | count | Count of succesive IBIs inside current epoch. Nonadjacent IBIs are not considered succesive. |

HRV_pNN20 | % | Percentage of absolute differences between successive IBIs that are greater than 20 ms. |

HRV_pNN50 | % | Percentage of absolute differences between successive IBIs that are greater than 50 ms. |
