EKG, ko Electrocardiogram, na'ura ce da ake amfani da ita don saka idanu da kimanta yiwuwar matsalolin zuciya a cikin majiyyaci.Ana sanya ƙananan na'urorin lantarki akan ƙirji, gefe, ko kwatangwalo.Sa'an nan kuma za a yi rikodin ayyukan lantarki na zuciya a kan takarda na musamman don sakamako na ƙarshe.Akwai abubuwa na farko guda huɗu akan injin EKG.
Electrodes
Electrodes sun ƙunshi nau'i biyu, masu bipolar da unipolar.Za a iya sanya na'urorin lantarki na bipolar akan duka wuyan hannu da ƙafafu don auna bambancin ƙarfin lantarki tsakanin su biyun.Ana sanya na'urorin lantarki akan ƙafar hagu da duka wuyan hannu.Unipolar electrodes, a gefe guda, suna auna bambancin ƙarfin lantarki ko siginar lantarki tsakanin na'urar magana ta musamman da ainihin saman jikin yayin da ake sanya su a kan hannu da ƙafafu biyu.Lantarki mai magana shine al'ada na bugun zuciya wanda likitoci ke amfani da shi don kwatanta ma'auni.Hakanan za'a iya haɗa su da ƙirji kuma a kula da duk wani canjin zuciya.
Amplifiers
Amplifier yana karanta siginar lantarki a cikin jiki kuma yana shirya shi don na'urar fitarwa.Lokacin da siginar na'urar ta kai ga amplifier an fara aika shi zuwa ma'ajin, sashin farko na amplifier.Lokacin da ta kai ga ma'ajin, siginar yana daidaita sannan a fassara shi.Bayan wannan, ƙararrawa daban tana ƙarfafa siginar ta 100 don ƙarin karanta ma'auni na siginar lantarki.
Haɗa Wayoyi
Wayoyin haɗawa wani yanki ne mai sauƙi na EKG tare da bayyananniyar rawa a cikin aikin injin.Wayoyin haɗin kai suna aika siginar da aka karanta daga na'urorin kuma aika zuwa amplifier.Waɗannan wayoyi suna haɗa kai tsaye zuwa na'urorin lantarki;Ana aika siginar ta hanyar su kuma an haɗa su zuwa amplifier.
Fitowa
Fitowar na'ura ce a kan EKG inda ake sarrafa ayyukan lantarki na jiki sannan a rubuta a kan takarda mai hoto.Yawancin injinan EKG suna amfani da abin da ake kira rikodin rikodi na takarda.Bayan fitarwa ya rubuta na'urar, likita yana karɓar kwafin ma'auni.Wasu injinan EKG suna rikodin ma'auni akan kwamfutoci maimakon na'urar rikodi ta takarda.Sauran nau'ikan masu rikodin su ne oscilloscopes, da na'urorin tef na maganadisu.Za a fara yin rikodin ma'aunin a cikin analog sannan a canza shi zuwa karatun dijital.
