Iyo EKG, kana Electrocardiogram, muchina unoshandiswa kutarisa uye kuongorora zvinogona kuitika zvemoyo mumurwere.Ma electrode madiki anoiswa pachipfuva, mativi, kana chiuno.Chiitiko chemagetsi chemoyo chinozorekodhwa papepa rakakosha regirafu kune mhedzisiro yekupedzisira.Pane zvinhu zvina zvakakosha pamushini weEKG.
Electrodes
Electrodes ine marudzi maviri, bipolar uye unipolar.Bipolar electrodes inogona kuiswa pamaoko nemakumbo kuyera musiyano wevoltage pakati pezviviri.Ma electrode anoiswa pagumbo rekuruboshwe uye nemaoko maviri.Unipolar electrodes, kune rumwe rutivi, kuyera musiyano wevoltige kana chiratidzo chemagetsi pakati peakakosha rengedzo electrode nenzvimbo chaiyo yemuviri uchiiswa pamawoko nemakumbo ese.Iyo referensi electrode ndeye yakajairika heart-rate electrode iyo vanachiremba vanoshandisa kuenzanisa zviyero.Vanogonawo kusungirirwa pachipfuva uye kutarisa chero kuchinja kwemoyo maitiro.
Amplifiers
Iyo amplifier inoverenga chiratidzo chemagetsi mumuviri uye inoigadzirira iyo yekubuda mudziyo.Kana chiratidzo che electrode chasvika kune amplifier chinotanga kutumirwa kune buffer, chikamu chekutanga cheamplifier.Kana yasvika pabuffer, chiratidzo chinodzikamiswa chobva chashandurwa.Mushure meizvi, iyo yekusiyanisa amplifier inosimbisa chiratidzo ne100 kuverenga zviri nani zviyero zvemagetsi masaini.
Kubatanidza Waya
Waya dzekubatanidza chikamu chakareruka cheEKG chine basa riri pachena mukushanda kwemuchina.Waya dzinobatanidza dzinoendesa chiratidzo kuverengwa kubva kune electrode uye kutumira kune amplifier.Idzi waya dzinobatanidza zvakananga kune electrodes;chiratidzo chinotumirwa kuburikidza navo uye chakabatanidzwa kune amplifier.
Output
Iyo inobuda mudziyo uri paEKG panogadziriswa magetsi emuviri wobva warekodhwa papepa regirafu.Michina yakawanda yeEKG inoshandisa inonzi paper-strip recorder.Mushure mokunge kubudiswa kunonyora chigadzirwa, chiremba anogamuchira zvakaoma-kopi yezviyero.Mimwe michina yeEKG inorekodha zviyero pamakomputa panzvimbo yepepa-strip rekodha.Mamwe marudzi emarekodha maoscilloscopes, uye magineti tape units.Izvo zviyero zvinotanga kurekodhwa muanalogi uye zvozoshandurwa kuita kuverenga kwedhijitari.
