Electrocardiography shine tsarin samar da electrocardiogram (ECG ko EKG), rikodin - jadawali na ƙarfin lantarki da lokaci - na aikin lantarki na zuciya ta amfani da na'urorin lantarki da aka sanya akan fata.Waɗannan na'urorin lantarki suna gano ƙananan canje-canjen lantarki waɗanda ke haifar da ɓarnawar tsokar zuciya ta zuciya tare da sake sakewa yayin kowane zagayowar zuciya ( bugun zuciya).Canje-canje a cikin tsarin ECG na yau da kullun yana faruwa a cikin cututtukan zuciya da yawa, gami da rikicewar bugun zuciya (kamar fibrillation na zuciya da tachycardia na ventricular), ƙarancin jini na jijiyoyin jini (kamar ischemia na zuciya da bugun jini), da rikicewar electrolyte (kamar hypokalemia da hyperkalemia). ).
A cikin ECG-lead 12 na al'ada, ana sanya na'urorin lantarki guda goma akan gaɓoɓin majiyyaci da kuma saman ƙirji.Gabaɗaya girman ƙarfin wutar lantarkin zuciya ana auna shi daga kusurwoyi daban-daban goma sha biyu (“jagora”) kuma ana yin rikodin na tsawon lokaci (yawanci daƙiƙa goma).Ta wannan hanyar, gabaɗayan girma da alkiblar dipolarization na wutar lantarki na zuciya ana ɗauka a kowane lokaci a cikin zagayowar zuciya.
Akwai manyan abubuwa guda uku zuwa ECG: P wave, wanda ke wakiltar depolarization na atria;hadaddun QRS, wanda ke wakiltar depolarization na ventricles;da kuma T, wanda ke wakiltar repolarization na ventricles.
