Electrocardiogram (ECG)

Menene ECG?

Electrocardiogram (kuma ana kiransa EKG ko ECG) gwaji ne da ke yin rikodin lokaci da ƙarfin siginar lantarki waɗanda ke yin bugun zuciya. Ta hanyar duban ECG, likitoci na iya samun fahimta game da bugun zuciya da kuma neman rashin daidaituwa.

Yadda Apple Watch ke ɗaukar ECG

Tun da Series 4, Apple Watch ya ƙunshi ginanniyar firikwensin zuciya na lantarki. *Da'irar:Lu'ulu'u na baya yana taɓa wuyan hannu, kuma yatsanka ya taɓa Digital Crown. Wannan yana haifar da rufaffiyar da'irar a cikin ƙirjin ku, yana ba da damar agogon don auna motsin wutar lantarki a cikin zuciyar ku. *Jagora Guda Daya:Wannan yayi daidai da aJagora IECG a cikin yanayin asibiti. Yana iya gano rhythm (Regular vs. Iregular) ammaba zai iya gano ciwon zuciya, lahani na tsari, ko ischemia ba(wanda ke buƙatar ECG na asibiti guda 12).

Fibrillation na Atrial (Afib)

Babban yanayin ECGs masu amfani da su ke nema shine Atrial Fibrillation. *Menene shi:Ƙungiyoyin na sama (atria) suna bugun hargitsi kuma ba bisa ka'ida ba, ba tare da daidaitawa da ƙananan ɗakunan ba (ventricles). *Hadarin:Jini na iya taruwa a cikin atria, ya zama guda, kuma ya tafi kwakwalwa, yana haifar da abugun jini.

Iyakoki (Abin da Ba Zai Iya Yi ba)

The Apple Watch ECG app ne FDA-barrantar, amma yana da tsauraran iyakoki. Yanaba zai iya bagano: * Ciwon zuciya (Myocardial Infarction) * Ciwon jini * Hawan jini * Ciwon zuciya * Sauran arrhythmias (kamar tachycardia na ventricular)

Lokacin da za a ɗauki ECG

• Alamomi:Idan kun ji "faɗawa," bugun zuciya mai sauri, ko bugun bugun zuciya.
• Sanarwa:Idan kun karɓi "Sanarwar Rhythm mara ka'ida" ko faɗakarwa "High/Ƙarancin Ƙimar Zuciya".
• Na yau da kullun:Lokaci-lokaci (misali, sau ɗaya a wata) idan kuna da abubuwan haɗari, amma ɗaukar shi yau da kullun ba tare da bayyanar cututtuka gabaɗaya ba dole ba ne ga manya masu lafiya.
