Kodi Magawo Anayi A Makina a EKG Ndi Chiyani?

EKG, kapena Electrocardiogram, ndi makina omwe amagwiritsidwa ntchito powunika ndikuwunika zovuta zamtima zomwe zingachitike kwa wodwala kuchipatala.Ma electrode ang'onoang'ono amayikidwa pachifuwa, mbali, kapena m'chiuno.Ntchito zamagetsi zapamtima zidzalembedwa pa pepala lapadera la graph kuti likhale ndi zotsatira zomaliza.Pali zinthu zinayi zazikulu pamakina a EKG.

Ma electrode

Electrode imakhala ndi mitundu iwiri, bipolar ndi unipolar.Ma electrode a bipolar amatha kuikidwa pamanja ndi miyendo kuti ayese kusiyana kwa magetsi pakati pa ziwirizi.Ma electrode amaikidwa pa mwendo wakumanzere ndi manja onse.Komano, ma elekitirodi a unipolar amayesa kusiyana kwa voteji kapena chizindikiro chamagetsi pakati pa maelekitirodi apadera ndi malo enieni a thupi pamene akuikidwa pa mikono ndi miyendo yonse.Electrode yowunikira ndi electrode yamtima yomwe madokotala amagwiritsa ntchito kuyerekeza miyeso.Angathenso kumangirizidwa pachifuwa ndikuyang'ana kusintha kulikonse kwa mtima.

Amplifiers

Amplifier amawerenga chizindikiro chamagetsi m'thupi ndikuchikonzekera ku chipangizo chotulutsa.Chizindikiro cha electrode chikafika pa amplifier chimatumizidwa ku buffer, gawo loyamba la amplifier.Ikafika ku buffer, chizindikirocho chimakhazikika ndikumasuliridwa.Pambuyo pake, amplifier yosiyanitsa imalimbitsa chizindikiro ndi 100 kuti muwerenge bwino miyeso ya zizindikiro zamagetsi.

Kulumikiza Mawaya

Mawaya olumikizira ndi gawo losavuta la EKG lomwe lili ndi gawo lodziwikiratu pakugwira ntchito kwa makinawo.Mawaya olumikizira amatumiza chizindikiro chowerengedwa kuchokera ku maelekitirodi ndikutumiza ku amplifier.Mawayawa amalumikizana mwachindunji ndi ma elekitirodi;chizindikirocho chimatumizidwa kupyolera mwa iwo ndikugwirizanitsa ndi amplifier.

Zotulutsa

Zomwe zimatuluka ndi chipangizo pa EKG pomwe ntchito zamagetsi za thupi zimakonzedwa ndikujambulidwa papepala la graph.Makina ambiri a EKG amagwiritsa ntchito chojambulira chojambulira mapepala.Pambuyo polemba zolemba chipangizocho, dokotala amalandira kopi yolimba ya miyeso.Makina ena a EKG amajambulitsa miyeso pamakompyuta m'malo mwa chojambulira pamapepala.Mitundu ina ya zojambulira ndi oscilloscopes, ndi maginito tepi mayunitsi.Miyezoyo imayamba kujambulidwa mu analogi kenako ndikusinthidwa kukhala kuwerenga kwa digito.
