Umphakathi Fitbit uthole isitifiketi sakhe namuhla I-Conformité Européenne (EC) ngohlelo lokusebenza lwe-ECG lwamawashi e-Fitbit Sense. Ihlola isigqi senhliziyo futhi ngaleyo ndlela ihlonze i-atrial fibrillation, isifo esihlasela abantu abangaphezu kwezigidi ezingu-33,5 emhlabeni wonke. Uhlelo lokusebenza lwe-EKG lwethulwa phakathi nesimemezelo somkhiqizo omusha ka-Agasti futhi luzotholakala kubasebenzisi be-smartwatch esisha se-Fitbit Sense emazweni amaningana e-European Union, okuhlanganisa ne-Czech Republic. Ngalesi sinyathelo, ukwazile ukuzibeka eceleni kuka-Apple Apple Watch, ephatha i-ECG evela ku-Series 4.
Ungaba nentshisekelo ku
Isifo senhliziyo sisaqhubeka nokuba ngesinye sezimbangela zokufa emhlabeni wonke, naphezu kokuba inkinga yezempilo egwemeka kalula. I-Atrial fibrillation yandisa ingozi yezifo ezimbi kakhulu njenge-stroke futhi kungaba nzima kakhulu ukuxilonga ngoba kuyisifo se-episodic esingase singabonisi noma yiziphi izimpawu. Ezinye izifundo zibika ukuthi abantu abangaba ngu-25% abaye baba nesifo sohlangothi babe nezinkinga nge-fibrillation ye-atrial. Ngeshwa, leli qiniso balithola ngemva kokushaywa unhlangothi.
“Ukusiza abantu ukuthi baqonde kangcono futhi baphathe impilo yenhliziyo yabo bekulokhu kuyinto ehamba phambili kwaFitbit. Uhlelo lokusebenza lwe-EKG lwenzelwe labo abafuna ukufunda okwengeziwe ngempilo yabo bese bexoxa nodokotela ngalokho abakutholile.” kusho u-Eric Friedman, umsunguli kanye ne-CTO yeFitbit futhi uyanezela “Ukutholwa kusenesikhathi kwe-atrial fibrillation kubalulekile, futhi ngijabule ngendlela emangalisayo ukwenza lezi zindlela ezintsha zitholakale kubantu emhlabeni jikelele. Bazobasiza ukuba bathuthukise impilo yenhliziyo, bagweme izinkinga ezinkulu futhi babe namandla okusindisa ukuphila.”
I-Fitbit Sense iyidivayisi yokuqala ye-Fitbit ene-EKG ekuvumela ukuthi uhlole impilo yenhliziyo okungahleliwe futhi isize ukuhlaziya isigqi senhliziyo esingajwayelekile. Abasebenzisi bavele babambe iminwe ku-bezel yensimbi yewashi imizuzwana engu-30 bese bathola okurekhodiwe ukuze babelane nodokotela wabo. Ngesikhathi sokufaka isicelo sokuthola isitifiketi se-CE, uFitbit wenze isilingo somtholampilo kulo lonke elase-United States. Ucwaningo luhlole ikhono le-algorithm lokuthola ngokunembile i-atrial fibrillation futhi lwabonisa ukuthi i-algorithm yedlule ngisho nevelu eqondiwe. Sekukonke, ithole amacala angama-98,7% futhi yayingenaphutha ngo-100% kubahlanganyeli abanesigqi senhliziyo esijwayelekile. I-Fitbit Sense iyidivayisi ethuthuke kakhulu yenkampani kuze kube manje futhi izidla umhlaba kuqala. Lena inzwa ye-electrodermal activity (EDA) ku-smartwatch esiza ukuphatha ingcindezi. I-Sense izophinda inikeze inzwa yokushisa kwesikhumba engalweni kanye nempilo yebhethri yezinsuku eziyi-6+.
Ukunikezwa komkhiqizo we-Fitbit Sense, ukubuka kwe-3QTR, ku Carisibopho kanye Graphite.
Ukuzinikela okubanzi empilweni yenhliziyo
Uhlelo olusha lwe-ECG luyingxenye yendlela ebanzi ye-Fitbit yokusungula impilo yenhliziyo. I-Fitbit iphayona ukuqapha izinga lokushaya kwenhliziyo ngobuchwepheshe bayo be-PurePulse, eyethule ngo-2014. Isebenzisa i-photoplethysmography (PPG) ukuze iqaphe ukushintshashintsha okuncane kwevolumu yegazi esihlakaleni ukuze ithole ukushaya kwenhliziyo. I-Fitbit iyaqhubeka nokuthuthukisa amathuluzi amasha ukusiza abantu baqonde kangcono futhi baphathe impilo yenhliziyo yabo.
Ukuqapha izinga lokushaya kwenhliziyo kwesikhathi eside (PPG) kanye nobuchwepheshe bokuqapha okungahleliwe (ECG) budlala indima ebalulekile, futhi i-Fitbit ihlose ukunikeza abasebenzisi ngazo zombili izinketho ngokusekelwe ezidingweni zabo ngabanye. Ukuqapha isigqi senhliziyo sesikhathi eside kungasiza ekuhlonzeni i-asymptomatic atrial fibrillation engase ingabonakali, kuyilapho i-EKG ingasiza labo abafuna ukuhlolwa futhi ingabonisana nempilo yabo nodokotela ngenxa yokuqoshwa kwe-EKG.
Ibhekisela ezenzweni zayo ezintsha zempilo yenhliziyo, uFitbit wethule ubuchwepheshe bePurePulse 2020 ngo-Agasti 2.0, okuwubuchwepheshe obuphambili kakhulu bokuqapha izinga lenhliziyo kuze kube manje. Manje ilandelela izinzwa eziningi kanye ne-algorithm ethuthukisiwe. Lobu buchwepheshe obuthuthukisiwe buhlinzeka abasebenzisi ngezaziso ezingaphakathi kwedivayisi nezinhlelo zokusebenza uma izinga lokushaya kwenhliziyo yabo lidlula noma lehla ngaphansi kwamanani amisiwe. Abasebenzisi abathola lesi saziso bangaqhubeka nokuphenya udaba kuhlelo lokusebenza lwe-Fitbit futhi kungenzeka baxhumane nodokotela wabo.
