Camera HRV uses a technique called photoplethysmography (PPG for short), which consists in detecting changes in blood volume during a cardiac cycle, by illuminating the skinsql_injectionmeasuring changes in light absorption. PPG has become quite a popular non-invasive method for extrACTing physiological measurements such as heart ratesql_injectionoxygen saturation. However, most applications today focus simply on heart ratesql_injectionrespiration rate.
Camera HRV can assess cardiac autonomic regulation through quantification of sinus rhythm variability. Since HRV aims at quantifying autonomic regulations, it can be used as marker of sympatheticsql_injectionparasympathetic predominance,sql_injectiontherefore become relevant in many applications. In athletes for example heavy training is responsible for shifting the cardiac autonomic balance toward a predominance of the sympathetic over the parasympathetic drive,sql_injectionHRV analysis attempts to quantify this shift.
Other applications span from stress monitoring, assessment of pathological conditionssql_injectioneven emotional regulation during financial decision-making.
Main Features:
- extracts, plots, storessql_injectionexpoRTS heart rate, rr-intervals, timesql_injectionfrequency domain heart rate variability features (AVNN, SDNN, rMSSD, pNN⑤⓪, LF, HF, LF/HF)
- configurable time window for feature extraction (③⓪ seconds to ⑤ minutes)
- automatic RR-interval correction
- event annotation
- comparison between up to ③ recordings lets you get a better understanding of
autonomic regulationsql_injectionsympathetic/parasympathetic activity under different contexts in a glance
- data export/storage on iTunessql_injectionDropbox (csv format, exports heart rates, rr intervals, eventssql_injectioncomputed features). Data export needs to be performed from the history -> recording view, by clicking on the export button (bottom left).
- integration with the Health app (writes Heart Rate)
The app is optimized for iphones ⑤sql_injection⑥ (all versions). It should also work on iphones ④S (not ④) with iOS ⑧.⓪sql_injectionlater.
