Chii chinokonzera magetsi emwoyo? Kusiyana kwemagetsi emagetsi emoyo akasiyiwa uye akarurama

Nheyo dzemagetsi yemwoyo (EOS) ndeimwe yemiganhu mikuru ye electrocardiogram. Iri izwi rinoshandiswa zvakashandiswa zvose muhutano uye muhutano hwekushanda, kuratidzira nzira dziri kuitika munhengo inonyanya kukosha yemuviri womunhu.

Nzvimbo yemagetsi emagetsi emwoyo inoratidza muongorori izvo zvinonyanya kuitika mumutsipa wemwoyo maminitsi ose. Iyi parameter ndeyomutengo wezvinhu zvose zvinokonzerwa nehupenyu hunoonekwa munhengo. Paunenge uchibvisa ECG, sarudzo imwe neimwe yehurongwa inonyora kushevedza kunopfuura pane zvakanyatsotsanangurwa. Kana iwe ukatumira tsika idzi kune hutano hutatu-hutano urongwa hwehutano, unogona kunzwisisa kuti majekiti emagetsi emwoyo ari kupi, uye kuverenga yecheno yacho nechekuremekedza nhengo yacho pachayo.

Ko electrocardiogram inobviswa sei?

Kuchengeta kweEGG kunoitwa mune imwe nzvimbo yepamusoro, zvakanyanya kunogona kudzivirirwa kubva kumakwikwi akasiyana-siyana emagetsi. Murwere anonyatsosvika pamubhedha, achiisa mutsipa pasi pomusoro wake. Kubvisa ECG, magetsi anoshandiswa (4 pamakumbo uye 6 pachifuva). Kunyora kwe electrocardiogram kunoitwa nekufema kwakanyarara. Muchiitiko ichi, kutengesa uye kugara kwepfungwa dzomukati, chinzvimbo chemagetsi emagetsi emwoyo uye mamwe emiganhu yakanyorwa. Iyi nzira iri nyore inokubvumira kuti uone kana pane kusakanganiswa mubasa remuviri, uye kana zvichifanira, tumira murwere kuti aone kubvunzurudza nemunhu anonzi cardiologist.

Chii chinoita kuti EOS igare?

Usati wataura nezvekufambisa kwemasikisi emagetsi, zvinokosha kuti unzwisise kuti chii chinokonzera chitendero chemoyo. Icho chigadziro chinokonzera kupfurikidza kwepfungwa pamamotocardium. Iko inofambisa moyo yehutachiona ishuputi yemisumbu fiber inobatanidza zvikamu zvakasiyana-siyana zvemuviri. Inotanga ne node ye sinus iri pakati pemiromo yezviputi zvakadzika. Uyezve, chirevo chacho chinoparidzirwa kune nhamba yeatrioventricular inowanikwa munzvimbo yezasi yeaniti yakakodzera. Bhaton inotevera inotora bundu reGeese, iro rinokurumidza kupindirana mumakumbo maviri - kuruboshwe uye kurudyi. Mumhepo, matavi echisimba cheGis anobva apfuura muPurkinje fibers, iyo inopinda mukati memwoyo wose.

Iko kushushikana kwakauya pamwoyo hakubvi kunokonzerwa nekutengesa nzira yeyo myocardium. Icho chivakwa chakaoma kunzwisisa uye maitiro akanaka, anonzwisisa zvishoma zvishoma mumuviri. Pakuvhiringidzika chero kupi zvako mumutambo wekutengesa, motokari yemagetsi yemwoyo inokwanisa kuchinja nzvimbo yayo, iyo ichanyatsogadziriswa pane electrocardiogram.

EOS nzvimbo yokusarudza

Sezvaunoziva, moyo wemunhu unoumbwa neatria maviri uye mabhiriki maviri. Mabhirikiti maviri eropa rekupararira (guru uye duku) rinovimbisa basa rinowanzoshandiswa nhengo dzose uye zvirongwa. Kazhinji, uwandu hwemyocardiyamu yezasi ye ventricle yakakura kupfuura iyo ye ventricle yakarurama. Icho chinotarisa kuti zvose zvinenge zvichinyanya kupfurikidza nechokumabvazuva chinonzi ventricle zvichange zvakasimba, uye magetsi emagetsi achave akatarirwa kwairi.

Kana isu mupfungwa tichichinja nzvimbo yechirongwa kune imwe nhatu-dimensional coordinate system, zvichaonekwa kuti EOS ichave pane imwe nzvimbo kubva pane +30 kusvika +70 degrees. Kazhinji kazhinji aya ndiwo maitiro akanyorwa paEECG. I-axis motokari yemwoyo inogonawo kuva munzvimbo yakabva pane 0 kusvika +90 degrees, uye izvi, maererano ne cardiologists, ndizvo zvinowanzoitika. Sei kusiyana kwakadaro kuripo?

Kazhinji nzvimbo yemagetsi emagetsi emwoyo

Pane zvikamu zvitatu zvakakosha zveEOS. Rwakati rwuri rwuri kubva pane +30 kusvika + 70 °. Izvi zvakasiyana-siyana zvinowanika muwandu hwakawandisa hwevarwere vakatarisa kuti vaone nyanzvi yehupenyu. Mhedzisiro yakananga yemagetsi emagetsi emwoyo inowanikwa mudiki, asthenic vanhu. Muchiitiko ichi, kona yacho ichabva pane +70 kusvika + 90 °. Ikosi yemagetsi yemwoyo yakanyanyisa pasi, yakazara varwere. Mumakadhi avo, chiremba acharatidza maonero eEOS kubva pane 0 kusvika + 30 °. Chimwe nechimwe chezvinhu izvi zvinosarudzwa ndezvekuti hazvidi uye hazvirevi kururamiswa.

Nzvimbo yepamusoro yenzvimbo yemagetsi yemoyo

Mamiriro ezvinhu umo magetsi emagetsi emwoyo akarambwa hausi pachake kuongororwa. Zvisinei, kuchinja kwakadaro pane electrocardiogram kunogona kuratidza kusakanganiswa kwakasiyana-siyana mubasa renhengo inonyanya kukosha. Zvirwere zvinotevera zvinotungamirira kuchinje chakakomba mukushanda kwekuitisa chirongwa:

• Chirwere chemoyo weCoronary;

• kusingaperi kwemoyo kusakona;

• kushaya mwoyo kwepakasiyana-siyana;

• kuberekwa kusagadzikana.

Kuziva pamusoro pezvirwere izvi, nyanzvi yemapurisa achakwanisa kuona dambudziko munguva uye otumira murwere kuti asarapwa. Mune zvimwe zviitiko, pakunyoresa kusakanganiswa kweEOS, murwere anoda rubatsiro rwekukurumidzira mumamiriro ekuchengetedza kwakanyanya.

Kusiyana kwemagetsi emagetsi emwoyo kuruboshwe

Kazhinji kacho, kuchinja kwakadaro paEECG kunoratidzwa nekuwedzera kwerutivi rezasi. Kazhinji izvi zvinoitika nekufambira mberi kwemoyo kusakundikana, kana muviri usingakwanisi kuita zvizere basa racho. Hazvirevi kuti nyika yakadaro inogona kukura kana iine arterial hypertension inoperekedzwa nehutachiona hwemidziyo huru uye kuwedzerwa kweropaiti. Nezvose izvi, mhepo inobhururuka inomanikidzwa kushanda pakupfeka uye kubvarura. Rusvingo rwaro runoita, zvichiita kuti kuputsika kusingadzivisiki kwekufamba kwemhepo inotungamira myocardium.

Kutsauka kwemaikisi emagetsi emwoyo kune kuruboshwe kunowanzoitika nekuderera kwe aortic aorta. Muchiitiko ichi, stenosis yevini yemagetsi iri panopinda kubva kuruboshwe inonzi ventricle inoitika. Ichi chiitiko chinopesana nekuputsa kwemazuva ose kubuda kweropa. Chikamu chacho chinoramba chichiri mumuganhu we ventricle yeruboshwe, zvichiita kuti iwedzere, uye, somugumisiro, kuwedzerwa kwemadziro ayo. Zvose izvi zvinokonzera kushanduka nguva dzose muEOS semugumisiro wemafambiro asina kufanira emapurisa pamakrocardium.

Kusiyana kwemajekisi emagetsi emwoyo kurudyi

Iyi nyika inoratidza zvakajeka hutachiona hwezvenyika yakanaka. Shanduko yakafanana inowanikwa kune dzimwe zvirwere zvekufemerwa (semuenzaniso, muhutachiona hwechirwere kana chirwere chisingaperi chisingakonzereri chirwere). Mamwe maitiro epenjemukari emwoyo anogonawo kukonzera kuwedzera mune ventricle yakarurama. Chokutanga pane zvose, zvakakosha kucherechedza stenosis yemapurmonary arteri. Mune mamwe mamiriro ezvinhu, kukundikana kwechigunha chinonzi tricuspid chinogona kutungamirirawo kuonekwa kwechirwere chakafanana.

Ndeipi ngozi yekuchinja EOS?

Kazhinji kazhinji kuperevedza kwesimbi yemagetsi yemwoyo kunosanganiswa nehutachiona hweimwe kana imwe mhepo. Ichi chimiro chiratidzo chekugara kwenguva refu isingagumi uye, sekutonga, hakudi kuti chirwere chemhepo chinokurumidza. Iko ngozi chaiye ndiko kushanduka kwemaikisi emagetsi maererano nekudzivirirwa kwechikwata. Muchiitiko ichi, kushungurudzika kwakaputsika pamakemikariyoyo, zvinoreva kuti kune ngozi yekusungwa kwemwoyo kamwe kamwe. Izvi zvinoda kupindira nokukurumidzira kwechirwere chemapirini uye kurapwa mune chimwe chipatara.

Nekuvandudzwa kwehutachiona huno, EOS inogona kurambwa zvose kune kuruboshwe uye kurudyi, zvichienderana nekuona kwekuita. Chikonzero chekuvharidzirwa kunogona kuva myocardial infarction, kuparadza kunotapukira kumutsipa wemwoyo, pamwe nekushandisa mamwe mishonga. Iyo inowanzoshandiswa electrocardiogram inokubvumira kukurumidza kuona, uye naizvozvo, kupa chiremba mukana wekurapa kurapwa uchifunga nezvezvinhu zvose zvinokosha. Muzviitiko zvakakomba, zvingave zvakakodzera kuisa pacemaker (pacemaker), iyo inotumira kutse zvakananga kumutsipa wepanyama uye nokudaro inoita kuti hutano huve hwakanaka.

Ko kana EOS ichishandurwa?

Chokutanga pane zvose, zvakakosha kufunga izvi, pachedu, kukanganisa kwemaziro emoyo hakusi iyo yekuisa kugadziriswa. Nzvimbo yeEOS inogona kukurudzira kuongororwa zvakanyanya kune murwere. Pachishanduko chipi zvacho pa electrocardiogram, nyanzvi yezvematori anogona kugona. Chiremba ane ruzivo achakwanisa kuziva chimiro uye chirwere, uyewo, kana zvichidikanwa, nyora kumwe kuongorora. Inogona kuva echocardioscopy yekuona mamiriro ezvinhu eatria uye mhepo inobhururuka, kutarisa ropa uye dzimwe nzira. Mune zvimwe zviitiko, kubvunzurudzwa kwevanyori vanofananidza kunotarisirwa kugadzirisa nyaya yekuenderera mberi kwekutarisira murwere.

Pfupisa, tinofanirwa kusimbisa pfungwa dzinokosha dzinokosha:

• Yakawanda yeEOS inokosha ndiyo yakabva kune +30 kusvika + 70 °.

• Kurongedza (0 kusvika + 30 °) uye nzvimbo (vertical (+70 to + 90 °) zvinowanikwa mukati memwoyo zvakanyatsonaka uye hazvirevi kukura kwehutachiona.

• Kuparadzana kweEOS kuruboshwe kana kurudyi kunogona kuratidzira kukanganisa kwakasiyana-siyana mumutambo wekutengesa wemwoyo uye kunoda mazano anyanzvi.

• Kushandurwa kweEOS kunoonekwa pamusana pehupenyu hakugoni kuiswa sekuongororwa, asi iyo ndiyo nguva yekushanyira nyanzvi yehupenyu.

Mwoyo inhengo inoshamisa inogonesa kushanda kwehurongwa hwose hwemuviri womunhu. Chero kushanduka kupi kunoitika mauri, hakubatsiri kukanganisa basa rehupenyu hwose. Nguva dzose maongorori ezverape uye nzira ye ECG ichabvumira kuzivisa munguva yekuonekwa kwezvirwere zvakakomba uye kudzivisa kukura kwezvinetso zvose munzvimbo iyi.
