Fitbit, yomwe ili ndi chimphona chaukadaulo ku US, Google, idalengeza dzulo kuti yalandila chivomerezo kuchokera ku US Food and Drug Administration chifukwa cha algorithm yake ya PPG (plethysmographic) kuti izindikire fibrillation ya atrial. Algorithm iyi idzapatsa mphamvu zatsopano zotchedwa Irregular Heart Rhythm Notifications pazida zosankhidwa zamakampani.
Atrial fibrillation (AfiS) ndi mtundu wamtundu wa mtima wosakhazikika womwe umakhudza anthu pafupifupi 33,5 miliyoni padziko lonse lapansi. Anthu omwe akudwala FiS ali ndi chiopsezo chochuluka kasanu chokhala ndi sitiroko. Tsoka ilo, FiS ndizovuta kuzindikira, chifukwa nthawi zambiri palibe zizindikiro zomwe zimayenderana nayo ndipo mawonetseredwe ake amakhala ongoyerekeza.
Zithunzi
Algorithm ya PPG imatha kuwunika mosadukiza kamvekedwe ka mtima wogwiritsa ntchito akagona kapena akupumula. Ngati pali chilichonse chomwe chingasonyeze FiS, wogwiritsa ntchitoyo adzadziwitsidwa kudzera pa Irregular Heart Rhythm Notifications Mbali, kuwalola kuti alankhule ndi wothandizira zaumoyo wawo kapena kufufuzidwa mowonjezereka za momwe alili kuti apewe mavuto aakulu a thanzi monga sitiroko yomwe tatchulayi.
Mtima wa munthu ukagunda, mitsempha ya magazi m'thupi lonse imatambasuka ndikumangika, malinga ndi kusintha kwa kuchuluka kwa magazi. Fitbit's optical heart rate sensor yokhala ndi algorithm ya PPG imatha kujambula zosinthazi mwachindunji kuchokera padzanja la wogwiritsa ntchito. Miyezo iyi imatsimikizira kuthamanga kwa mtima wake, komwe ma aligorivimu amawasanthula kuti apeze zolakwika ndi zizindikiro za FiS.
Mutha kukhala ndi chidwi ndi
Fitbit tsopano ikhoza kupereka njira ziwiri zodziwira FiS. Yoyamba ndikugwiritsa ntchito pulogalamu ya kampani ya EKG, yomwe imalola ogwiritsa ntchito kudziyesa okha kuti adziwe za FiS ndikujambulitsa EKG yomwe imatha kuwunikiridwa ndi dokotala. Njira yachiwiri ndiyo kuyesa kwanthawi yayitali kwa kugunda kwa mtima, komwe kungathandize kuzindikira FiS yopanda zizindikiro, zomwe mwina sizingadziwike.
Gawo la PPG algorithm ndi Irregular Heart Rhythm Notifications posachedwapa lipezeka kwa makasitomala aku US pazida zosiyanasiyana za Fitbit zotha kugunda kwamtima. Kaya idzafalikira kumayiko ena sizikudziwika panthawiyi.
