Rakagadzirirwa ECG rinoshandiswa mumaroto emaroto

Nzira huru yekuongororwa kwemyocardial infarction ndiyo kuongorora kwekugadzirisa electrocardiographic ye coronary circulation disorders. ECG - chidzidzo chinonyanya kukosha kana pane chirwere chepfungwa, ichisimbisa kuongororwa kwechirwere ichi. Haikwanise kuchinjwa nedzimwewo, sezvakaita ECG mu blockades.

Myocardial infarction kana necrosis inoratidzirwa nekusingaperi-kushanduka mumashuga emasumbu. Necrotic tissue haibatanidzi mufaro. Nokudaro, paEECG pamusoro pewecrosis site, kukanganisa kwe ventricular myocardial depolarization inoonekwa, iyo inoratidzwa nekushandurwa mu QRS yakaoma. Iko kushanduka kunosvika pakuderera kweR wave nekudzika kwe Q wave.Myocardial infarction inoratidzirwa nekushanduka kwekuchinja mu electrocardiogram. Zvinoratidza kuvapo kwezvikamu zvitatu zvekurwadziwa kwemoyo - nzvimbo yepamusoro ye necrosis, nzvimbo yekuparara yakakomberedza necrosis, uye nzvimbo inoshandiswa inopoteredza nzvimbo yekukuvara.

Nharaunda yezvinyorwa zvisingashandurwi kana myocardial infarction inogona kuvhara kukwana kose kwemasimba rusvingo rwemoyo. Kurwisa kwemwoyo kwakadaro kunonzi kudarika. Kana necrosis iri pasi pe endocardium - subendocardial, pasi pe epicardium - subepicardial, muhupamhi hwemutsipa wemwoyo - mukati.

Pamusoro peEECG, pasinei nechirwere chechirwere chemukati, chimiro chekare chinowanikwa, chinotarirwa nenzvimbo, yakadzika, kupararira kwemoyo wemusana kunokanganisa uye danho rekuita. ECG zviratidzo zvemyocardial infarction zvinopesana zvichienderana nesiteji chechirwere.

Chimwe chiitiko chemyocardial infarction chinogoverwa muzvikamu zvina: acute, acute, subacute uye kupera kwepakati.

ECG neyomyocardial infarction mumusasa wakaoma zvikuru

Chirwere ichi chinotanga nechepamusoro payo ye myocardial infarction. Iyi ndiyo nguva kubva pakutanga kwemaitiro epamycardial ischemia pakuumbwa kwezviratidzo zve necrosis. Pamusoro peEECG, danho iri rinoratidzika nechitarisiko cheArched ST chikamu chinosanganiswa neR kuve kune rumwe rutivi uye T inotsigira kune imwe.Naizvozvo, Parc arc inowanzoenderana neyomukati myocardial kana chiratidzo che "cat's back" chinoumbwa.

ECG ne acute myocardial infarction

Muchikamu chakaoma chechirwere, nzvimbo ye necrosis inozopedzisira yaumbwa uye myomalacia inokura (kunatsiridza kwechigadzirwa chemyocardium). Chirwere chema Q chinowanikwa paEECG uye zvishoma nezvishoma chinova chakafara uye chakadzika, chinoratidza kukurudzirwa kwenzvimbo ye necrosis. Panguva imwe chete nechitarisiko chezino ichi, chikamu cheT ST chinotanga kuderera, izvo zvinoratidza kuderedzwa kwenharaunda. Panguva imwecheteyo inotanga kuumba rakakosha rakaipa mazino T.

ECG ne myocardial infarction mu subacute

Munguva yechirwere cheshuga, maitiro ekutanga echakupisa sangano apera. Chiratidzo chikuru cheEGG chemukati uyu ndechekuderedza zvishoma kwechikamu che ST ichienda kune mumwe oga uye kugadzirisa kwekupedzisira kwepakadzika, yakatarisa, inonzi "coronary wave." Panguva ino, Zubets Q inowana maitiro ayo, iyo inoramba ichishandurwa kwemakore mazhinji kana masara ehupenyu.

ECG neyemyocardial infarction muchikamu chechikamu

Muchikamu chechikamu, ruvara rwunogadzirwa. Chimwe chinhu chinowanikwa pachigadziro ichi ndechokuti nzvimbo ye ST iri pachidimbu chesoelectric. Pamusoro pekutamiswa kwechirwere chechirwere chechirwere chemafu uye chimiro chisina kumira T chinopupurira. Nokufamba kwemazuva, hukuru hwehuipi T inogona kuderera, kunyange mazino akanaka eT anogona kuonekwa.

Nekadiki-focal myocardial infarction, ECG kuchinja kunogumira kudengenyeka kwechikamu cheS ST kubva kune imwe nzvimbo zvichidzika kumusoro kana pasi, zvichienderana nenzvimbo yechipupuriro, uye kuchinja kweT wave.

Myocardial infarction inowedzera kunyanya mubhokisi rezasi. Kunzvimbo yekutarisa kweecrosis mumamotokari inoratidzirwa nechitarisiko che electrocardiographic zviratidzo zvinokonzerwa neparction mumutungamiri wakafanana.
