Gyara ECG yayi canje-canje a cikin infarction na sirri

Babban Hanyar ganewar asali da tsokar zuciya infarction - da bincike na electrocardiographic sharudda ga keta da jijiyoyin zuciya wurare dabam dabam. ECG - binciken da ba za a iya gwadawa ba idan akwai ciwon zuciya, yana tabbatar da ganewar cutar. Ba za'a iya maye gurbinsu da wani ba, kamar ECG a cikin garuruwa.

Ƙaƙwalwar ƙwayar cuta ko ƙwayoyin ƙwayoyin ƙwayoyin cuta yana nuna halin canjin da ba a sake faruwa ba a cikin ƙwayoyin tsoka. Kwayoyin necrotic ba ya shiga cikin tashin hankali. Sabili da haka, a kan ECG a kan shafin necrosis, an gano wani ɓangaren ƙananan kwakwalwa na katako, wanda aka nuna ta canji a cikin ƙwayar QRS. Wannan canji ya ƙunshi raguwar rawanin R da zurfafa ƙwaƙwalwar Q. Ƙarƙashin ƙananan ƙwayar cuta yana nuna yanayin ƙwayar canji a cikin electrocardiogram. Yana nuna ci gaba da ɓangarori uku na ciwon zuciya - cibiyar tsakiya na necrosis, ɓangaren lalacewar kewaye da kwayar necrosis, da kuma yankin mai ƙaddarawa a kusa da yankin rauni.

Yankin canza jiki a cikin ƙwayoyin jiki idan akwai wani ɓarna na ƙananan ƙwayar cuta zai iya rufe dukan kauri daga murfin murji na zuciya. Irin wannan ciwon zuciya yana kiransa mai juyi. Idan necrosis yana ƙarƙashin endocardium - subendocardial, karkashin epicardium - subepicardial, a cikin kauri daga cikin zuciya tsoka - intramural.

A kan ECG, komai yanayin asibiti na ƙwayar cuta, an lura da tsarin yau da kullum, wanda aka ƙaddara ta wuri, zurfin, yada lalacewar ƙwayar tsoka da kuma mataki na tsari. ECG ãyõyin tsokar zuciya infarction bambanta dangane da mataki da cutar.

Haka kuma cutar ta fara tare da babban mataki na infarction m. Wannan shi ne lokacin daga farawa na ischemia mai matsananciyar cututtuka ga samuwar alamomin necrosis. A kan ECG, wannan mataki yana nuna bayyanar wani sashi na ST wanda ya haɗa da R a kan gefe ɗaya da kuma T a kan ɗayan. Saboda haka, Pardi arc na hali na fatar hawan na sirri ko kuma alamar "cat".

ECG tare da ƙananan infarction m

A cikin babban mataki na infarction, an kafa shafin necrosis kuma myomalation na tasowa (softening of myocardium canzawa). Kwayar maganin Q a kan ECG ya zama mai zurfi da zurfi, wanda ke nuna ci gaba da yankin necrosis. A lokaci daya tare da bayyanar wannan tasirin, matakin ST yana fara karuwa, wanda ya nuna raguwa a cikin lalacewar yankin. A lokaci guda fara fara kirkiro hakori.

A lokacin matakan da suka dace, an fara tafiyar da tsarin farko na kungiya. Babban alamar ECG na wannan mataki shi ne rage ragowar sashen ST na zuwa isoline da kuma ƙarshe na karshe na zurfafawa, wanda aka kwatanta da shi, abin da ake kira coronary waves. A wannan lokaci, Zubets Q ta samo siffarsa, wadda ba ta canzawa har shekaru da yawa ko rayuwa.

A cikin wasan kwaikwayo, ana kara karar da wuya. Halin halayen wannan mataki shine wuri na sashen ST a kan layi mai layi. Game da ƙaddarar da aka canjawa wuri da ƙwararren ƙwayar Q da kuma hakikanin hakikanin hakikanin hakikanin T.Bayan lokaci, girman girman t T teza zai iya ragewa, ko da haƙƙin hakori na T zai iya bayyanawa.

Tare da infarction ƙananan ƙananan ƙwayar cuta, gyaran ECG an iyakance shi zuwa wani ƙananan motsi na sashen ST daga isoline sama ko ƙasa, dangane da wurin da ƙananan infarction, da kuma canza tayin T.

Ƙarƙashin ƙwayar cuta na tasowa ya fi girma a cikin ventricle hagu. An gano ma'anar necrosis a cikin myocardium ta hanyar bayyanar alamomi na lantarki da ke nuna alamar ƙaddamarwa a cikin matsala.
