Pulse HRV by Camera BLE ECG

ECG for Everybody

Mayelana nalolu hlelo lokusebenza

Hlola: Ukushaya kwenhliziyo (Ukushaya kwenhliziyo), Ukuguquguquka Kwezinga Lenhliziyo (HRV), Ukufaneleka, Izinga Lokucindezeleka, izibalo ze-Cardio zilandelela ukuqhubeka nokunye usebenzisa ikhamera ye-smartphone, i-ECG noma i-BLE (idivayisi eyengeziwe iyadingeka).

Uhlelo lokusebenza luthola ukushaya kwenhliziyo lisebenzisa:
1. Ikhamera ehlanganisiwe (PPG-Photoplethysmography signal processing)
2. I-BLE inikwe amandla idivayisi eyengeziwe yokufaneleka
3. I-ECG yeselula izwa i-extender idivayisi eyengeziwe etholakalayo ngoku-oda kusengaphambili

Isignali ye-PPG-Photoplethysmography ithathwa kusetshenziswa ikhamera ye-smartphone ngokubeka umunwe kulensi yekhamera. Isignali ye-PPG ingumphumela wezinguquko zevolumu yegazi ekujikelezeni kwe-peripheral.

Uhlelo lokusebenza luhlinzeka ngemiphumela yokuhlaziya efingqiwe (njengamakilasi aqala Kokumpofu .. kuya kuMgijimi) kusetshenziswa ukuhlaziya kwe-HR kanye ne-HRV (Ukuguquguquka Kwezinga Lenhliziyo).

Eminye imiyalelo yokuhlaziya ukuhlaziya:

Izinga lokushaya kwenhliziyo elivamile kubantu abadala lisukela ku-40 kuya ku-70 beat ngomzuzu. Izinga lokushaya kwenhliziyo eliphansi lapho uphumule lisikisela ukusebenza kwenhliziyo okusebenza kahle kakhulu kanye nokuqina okuphelele.

Ukuhlukahluka Kwezinga Lenhliziyo
I-HRV ihlotshaniswa nempilo yenhliziyo, ingcindezi, ukuqeqeshwa kwezemidlalo, impilo yemizwa, nokuqina.
I-rMSSD (I-Root Mean Square of Successive Differences) iyinkomba eqinile yezinga lokufaneleka lilonke. Zama ukuba ne-rMSSD engaphezu kuka-40ms, ulandelele ukuqhubeka kwakho kugrafu yomlando wohlelo lokusebenza.
Amagrafu we-HRV abonisa izinguquko ku-pulse.

I-Cardio
Thola izinzuzo ku-Cardio usebenzisa isibalo sezindawo nemiyalo kuhlelo lokusebenza.

Ukuhlaziya isikhathi
Ngokuvamile, ukuhlaziywa okude kunikeza imiphumela ethembeke kakhulu.
* Imizuzwana engu-10-15 yanele Isilinganiso Senhliziyo
* Ukuhlaziywa kwemizuzwana engama-30 kunikeza izilinganiso ze-HRV
* Ukuhlaziywa komzuzu owodwa kunikeza izilinganiso ezithembeke kakhulu ze-HRV
* Ukuhlaziywa kwemizuzu emibili+ kuyadingeka ukuze kuhlaziywe okuthembekile

I-ECG yawo wonke umuntu https://ecg4everybody.com isisesigabeni sokuqala futhi sivulekele ukubambisana. Idivayisi yethu ye-Mobile ECG sensing extender isilungele uku-oda kusengaphambili. Kuyisixazululo esiyingqayizivele seselula se-ECG senzwa esingasebenza ngaphandle kwama-electrode futhi sithwebule amashaneli e-ECG ayisithupha anomklamo wamanani aphansi weshumi nambili.

Lolu akulona uhlelo lokusebenza lwezokwelapha.
