mhrv is a matlab toolbox for calculating Heart-Rate Variability (HRV) metrics
from both ECG signals and RR-interval time series. The toolbox works with ECG
data in the PhysioNet WFDB data format.
WFDB wrappers and helpers. A small subset of the PhysioNet WFDB tools are wrapped with matlab functions, to allow using them directly from matlab.
ECG signal processing. Peak detection and RR interval extraction from ECG data in PhysioNet format.
RR-intervals signal processing. Ectopic beat rejection, frequency filtering, nonlinear dynamic and fractal analysis.
HRV Metrics. Calculating quantitative measures that indicate the activity of the heart based on RR intervals using all standard HRV metrics defined in the literature.
Configuration. The toolbox is fully configurable with many user-adjustable parameters. Everything can be configured either globally with human readable YAML config files, or when calling the toolbox functions via matlab style key-value pair arguments.
Plotting. All toolbox functions support plotting their output for data visualization. The plotting code is separated from the algorithmic code in order to simplify embedding this toolbox in other matlab applications.
Top-level analysis functions. These functions work with PhysioNet records and allow streamlined HRV analysis by composing the functions of this toolbox. Supports multi-record batch analysis for calculating HRV features of large datasets.
