I-Apple yethule uchungechunge lwe-Apple Watch 4 futhi abagxeki bayihalalisile njengomkhiqizo omuhle kakhulu owethulwe kulo Septhemba 12 owedlule. Futhi akazishodi ngezizathu.
Enye yezinto ezintsha ezilethwayo yi ikhono lokwenza i-electrocardiogram. Akuyona into entsha ye-Apple Watch kuphela, iyintsha kuzo zonke izici futhi lokho kuzoba nzima kakhulu ukuyenza kabusha ezinye izinkampani. Empeleni, i-OTC electrocardiograph yokuqala (idivayisi yezokwelapha ezithengiswayo). Namuhla sizochaza konke ukuze ungamosheki.
Ake siqale ngezisekelo. I-electrocardiogram (ECG) isilinganiso esingaqondile somsebenzi kagesi wenhliziyo. Noma, ngamanye amagama, ngokuncipha ngakunye, inhliziyo iyaphindaphinda futhi idicilele phansi, yakha insimu kagesi ebanjwa ngama-electrode ngokuvamile atholakala esikhunjeni. Kulokhu, i-Apple Watch ine-electrode ebusweni bewashi obungezansi nenye esigaxeni sedijithali.
I-electrocardiograph ibamba lezi zilinganiso zikagesi futhi iziveze kugrafu. Sizobona ekunqobeni i-voltage (mV) naku-abscissa isikhathi (imizuzwana).
Akunasimo lapho i-electrocardiographs (i-Apple Watch ifakiwe) ikhiqiza amandla kagesi yenza inhliziyo, lokhu kuzokwenza i-ECG yonke ingasebenzi. Kepha kungcono ukukucacisa, ngoba ufunda yonke into laphaya.
Ama-electrocardiographs esibhedlela asebenzisa ama-electrode ayishumi (munye esitho ngasinye futhi eziyisithupha ku-thorax). La ma-electrode asivumela ukuthi sakhe imikhondo eyishumi nambili, okungukuthi, izilinganiso eziyishumi nambili ezihlukile (njengoba ama-electrode "ayibona" evela ezindaweni ezahlukahlukene) zomsebenzi ofanayo kagesi (owenhliziyo yakho), okwenza kube lula ukuthola izinguquko ezahlukahlukene.
Ngakolunye uhlangothi, i-Apple Watch inama-electrode amabili kuphela. Lokhu kusivumela ukuthi sithole okukodwa. Ngamanye amagama, isivumela ukuthi sikwazi "ukubona" inhliziyo ngombono owodwa. Kulokhu, njengoba ama-electrode womabili esemaphethelweni aphezulu, kungumholi I. Uma uke wenziwa i-ECG, uzobe ubonile ezinye izinhlamvu (I, II, III, aVR, aVL, aVF, nakuV1 okuya ku-V6) okuhambisana nokuvela kokujwayelekile okuyishumi nambili kwendabuko. Yebo, okokuqala okuvela, mina, nguyena othola i-Apple Watch.
Noma kunjalo, lokhu kudluliselwa okukodwa kunganikeza imininingwane ebaluleke kakhulu. Eqinisweni, uma ihunyushwe ngudokotela, ingahlola izifo eziningi. Noma kunjalo, ngicabanga ukuthi umsebenzi we-Apple Watch akukhona ukufaka ama-ECGs atholwe esibhedlela, kepha ukudlulisela umuntu kudokotela noma egumbini labezimo eziphuthumayo.
Ngokombono kadokotela, i-ECG ingumngani wakho omkhulu. Kuyindlela elula, eshibhile, esheshayo, yokuhlola enikezela ngemininingwane eminingi, okuningi kakhulu kunalokho ongakusola. I-ECG izosivumela ukuthi sazi ukuthi kungenzeka yini isifo senhliziyo esiyischemic (i-myocardial infarctions), isifo senhliziyo se-valvular, isifo senhliziyo esizelwe, ukushaya kwenhliziyo, ukungajwayelekile kwe-anatomical, ukungahleleki kahle kwe-hemodynamic, ukungalingani kwe-electrolyte, izifo ze-pericardial, ... Kafushane, izifo eziningi ezimbi kakhulu futhi kuyaphuthuma njengoba kuwukuhlasela kwenhliziyo (imbangela ehamba phambili yokufa kwabesilisa neyesibili kwabesifazane eSpain) engatholwa yi-ECG, ngisho ne-shunt. Futhi hhayi isifo senhliziyo kuphela, i-hyperkalemia, isifo esibi se-electrolyte, esingatholwa yi-ECG efana naleyo eku-Apple Watch.
Ngakho-ke, usizo lwe-Apple Watch - uDkt.Benjamin uthe kuleso sethulo - akulona kwi-ECG ngasese, kulele ekubeni yi-ECG esiyigqoka esihlakaleni sethu. Noma kunini, noma kuphi, singathola i-ECG ngemizuzwana engama-30. Lokhu kwenza kube lula ukuthola okuthile okubaluleke kakhulu ku-cardiology, i-ECG ngesikhathi sezimpawu. Lokhu akunjalo lapho uya kudokotela lapho kungenzeki lutho kithina - njengoba kuvame ukwenzeka ngesikhathi sokubonisana- futhi kwenziwe ne-ECG lapho kungenzeka khona ukuthi kungabonakali lutho ngoba azikho izimpawu ngaleso sikhathi.
I-Apple Watch iyodwa ibonakala ikwazi ukuthola isigqi sesinus (esijwayelekile), kanye nokuphazamiseka kwesigqi okufana ne-atrial fibrillation (AF). Kepha amandla weqiniso wokuxilonga we-Apple Watch - akumele siyikhohlwe - adlula kudokotela. Kuzoba kithi ukwenza i-ECG uma sikubona kufanelekile, kepha kuzoba kudokotela ukuthi ayitolike.
I-Apple Watch ECG izotholakala ekupheleni konyaka e-US., lapho inketho yabantu baseMelika izocushwa. Lokhu kukhawulelwa e-USA kungenxa yemvelo ye-ECG, njengoba kuyidivayisi yezokwelapha, idinga ukuvunywa yiziphathimandla ezahlukahlukene.
E-US, yi-FDA evuma amadivayisi wezokwelapha futhi, ngokusho kuka-Apple, isivele ivumile uchungechunge lwe-Apple Watch 4. ESpain, kufanele silinde i-AEMPS (iSpanish Agency for Medicines and Health Products) kanye ne-EMA (European Medicines Agency) ukuthi banikeze imvume. Noma kunjalo, iqiniso lokuthi i-FDA isivele livumile ukuthi livume kule ngxenye ye-Atlantic indaba yesikhathi.
Umbuzo ukuthi leli khono lizofika ngaphambi kochungechunge lwe-Apple Watch 5 (ngonyaka ozayo mhlawumbe). E-US kuhlelwe ukuphela konyaka ngaphandle kokukhulunywa ngomhlaba wonke, ngakho-ke mhlawumbe kuze kube yi-2019 ngeke siyibone i-ECG eSpain.
Noma kunjalo, isikhathi lapho samukelwa khona, kuyindaba yokuyisebenzisa. Akufani nenguqulo ye-LTE ye-Apple Watch ebithengiswa kuphela emazweni asekelwayo. Kulokhu, siyaqonda ukuthi lonke uchungechunge lwe-Apple Watch 4 lunehadiwe edingekayo yokwenza i-ECG.
