Camera Heart Rate Variability is the first app that lets yourecord, plot and export time and frequency domain Heart RateVariability Features (as well as heart rate and RR intervals),without requiring any heart rate monitor. Camera HRV uses atechnique called photoplethysmography (PPG for short), whichconsists in detecting changes in blood volume during a cardiaccycle, by illuminating the skin and measuring changes in lightabsorption. PPG has become quite a popular non-invasive method forextracting physiological measurements such as heart rate and oxygensaturation. However, most applications today focus simply on heartrate or respiration rate. Camera HRV can assess cardiac autonomicregulation through quantification of sinus rhythm variability.Since HRV aims at quantifying autonomic regulations, it can be usedas marker of sympathetic or parasympathetic predominance, andtherefore become relevant in many applications. In athletes forexample heavy training is responsible for shifting the cardiacautonomic balance toward a predominance of the sympathetic over theparasympathetic drive, and HRV analysis attempts to quantify thisshift. Other applications span from stress monitoring, assessmentof pathological conditions and even emotional regulation duringfinancial decision-making. Main Features: - extracts, plots, storesand exports heart rate, rr-intervals, time and frequency domainheart rate variability features (AVNN, SDNN, rMSSD, pNN50, LF, HF,LF/HF) - configurable time window for feature extraction (30seconds to 1 minute) - automatic RR-interval correction - dataexport/storage on Dropbox or via email (csv format, exports rrintervals, and computed features).

VitaPulse: express diagnostics of the human organismstate«VitaPulse» — diagnostic mobile app that allows any personwithoutusing expensive medical equipment independently controlhis/herfunctional health state, learn level of healthassessment,adaptability of organism, level of stress, balanceexpenditure /recovering energy, as well as improve the quality oflife andreduce the risk of unexpected health problems. Algorithmsapp andinterpretation of obtained results are based on numerousscientificstudies and recommendations European Society ofCardiology and theNorth American Society of Pacing andElectrophysiology. Appsupports (full version only) Holtermonitoring - a method by whichdiurnal monitoring of functioning ofheart. It uses wearable heartrate sensor (eg. Polar H7, Mio Link),which provides registrationand transfer of information on the workof the heart in asmartphone. Demonstration Holtersession:https://youtu.be/iB9wzhoyTMc How does it work? Mobile apppulsediagnosis «Vita Pulse» real-time monitors changes in heartrhythm.This does not require any expensive special sensors ordevices,because the heart rate registration performed using onlythebuilt-in camera of your smartphone (there is synchronizationmodewith the heart rate sensors). App with using the camera readsbloodcirculation in finger, which gives necessary information onwork ofheart. After pulse being detected, the registration oftheinterpulse intervals and recording of the cardiointervalogramareconducted. The duration of each cardiac cycle differs fromtheprevious and app is estimated with an accuracy of onemillisecond.Sequential change durations cardiac cycles forms acomplex rhythmthat is analyzed by app. After finishing examinationprogramautomatically generates health-physiological conclusionandcalculates parameters of functional state, based on heartratevariability (HRV) - a modern method for research offunctionaldiagnostics. Why the need «VitaPulse»? 1. Regularmonitoring of thehealth status of all family members. Allows you tostop waitingwhen the disease was coming suddenly, and respond inadvance.Typically, first clinical manifestation of disease andtreatment,respectively to the doctor preceded by a long incubationperiod,when the disease is hidden matures. «VitaPulse» revealsthebeginning of the disease process in a timely manner. Booked -isforearmed and can take action. 2. Stress control. The mainreasonfor most of the diseases of modern man - it's stress. «Alldiseasesof the nerves» - there is a narrow-minded view. And in mostcasesit is absolutely true. «VitaPulse» help control the currentlevelof stress and live a long life. Information about what thestresslevel is dangerous, has been well studied by scientists andisexpressed as a clear digital indicators. These scientific datahavebeen developed and are now available to any user «VitaPulse».3.«VitaPulse» easily integrated into many methods of treatmentandself-medication. Massage, wellness exercises, physiotherapy,herbalmedicine, yoga, fitness, medication, etc. - all thisrequiresmonitoring. Regular monitoring of the functional statusbefore andafter the procedures will evaluate the effectiveness oftheselected method and, if necessary, correct it. 4.«VitaPulse»applies in sports practice for early detection ofproblems organismadaptation to physical stress and overtrainingstate,implementation of immediate control over the process ofphysicaltraining with a view to optimization, which is aprerequisite forachieving high results. App is compatible withPolar H7, Mio Linkand other heart rate sensors Bluetooth LowEnergy, and also abuilt-in heart rate sensor samsung.
