Huringa phasic ECG i infarction myocardial

Ko te tikanga matua o te tātaritanga o te infarction myocardial - te tātaritanga o ngā paearu electrocardiographic mo maumaui o te tohatoha coronary. ECG - he ako mahuinga i myocardial whakau i te tātaritanga o te mate. e kore e taea te whakakapi te reira i tetahi atu, me te ECG i te blockades.

infarction myocardial necrosis ranei āhuatanga e huringa rangitahi i roto i muka uaua. e kore e kiko Necrotic tango wahi i roto i te whakahaere o te excitation. Na reira, i whakaritea ECG mo ngā wāhi o te necrosis ko te takahi o te depolarization o te myocardium ventricular, e faaite i te huringa o te matatini QRS. Tenei huringa Ko ki te whakaiti i te R-poipoi, me te faahohonuraa e o te Q. niho āhuatanga infarction myocardial e huringa hihiri i roto i te hiko-. E whakaatu ana te reira i te aroaro o toru rohe myocardial - te necrosis wahi pokapū, rohe whara a tawhio noa necrosis me ischemia rohe e takoto ana huri noa i te rohe papaka.

kia hipokina wahi kikokiko puta necrotic infarction myocardial te matotoru katoa o te uaua taiepa ngakau. huaina ana tēnei ko te transmural myocardial. Ki te he necrosis raro endocardium - subendocardial i raro i te epicardium - subepicardial, i roto i te matotoru o te uaua ngakau - intramural.

Te ECG, takitahi o nga momo haumanu o myocardial, kite tauira he pikitia, whakaritea nei e te hohonu localization, tohatoha, me te whakangaromanga o te ngakau tukanga uaua taahiraa. ECG tohu o myocardial infarction tēnā i runga i te atamira o te mate.

Angamaheni mō te infarction myocardial te wehea ki wha wāhanga: whakapeka, whakapeka, subacute, me te taahiraa o te scarring.

ECG infarction myocardial i roto i te wā whakapeka

tīmata te mate ki te wā whakapeka o infarction myocardial. Ko te wa i te ahua o te ischemia myocardial koi i mua i te hanganga o nga tohu o te necrosis tenei. Te ECG, te āhuatanga tenei wā e te ahua o te wāhanga whakaarahia arcuate ST, e hanumi i tetahi taha ki te R niho, i te tahi atu - ki te niho i hanga te kupu T. mo te pewa angamaheni Pardee infarction myocardial tohumate "hoki o ngeru" ranei.

ECG infarction myocardial i roto i te wā whakapeka

I roto i te wāhanga whakapeka o necrosis myocardial wahi hopea i hanga, me te whakawhanake miomalyatsiya (fakamolū infarction whakarerekē). i hanga te ECG te Q. niho pathological ia āta riro whanui, me te hohonu, e tohu ana i te whanaketanga o te necrosis. Tukutahi ki te ahua o te niho tīmata ki te peka ke ST wāhanga e whakaatu te whakaiti i roto i te rohe pakaru. I te wa ano haamata te reira ki te hanga i te koi T. tōraro prong

ECG infarction myocardial i roto i te wā subacute

I roto i te atamira subacute oti nga tukanga tuatahi o te whakahaere o te nawe. Ko te āhuatanga matua o tenei atamira, te ECG ko te hekenga äta i roto i te wāhanga ST me te aratau whakamutunga ki te hanganga o te hohonu, hangarite oka, niho coronary pera-ka karanga E. Kāniwha Q riro tona āhua i tenei wa, e noho tonu i runga i te tau, me te mau tonu hoki te ora.

ECG infarction myocardial nawe i roto i te taahiraa

Te atamira nawe, te hiri o te nawe. He āhuatanga āhuatanga o tenei wā ko te wāhi wāhanga ST i runga i te raina isoelectric. I te myocardial tohu Q niho rerekē, me te T. prong stably kino Neke wa, kia heke ai te uara o te kino T-poipoi, kia ara puta reira T. niho pai

A, no te e whāiti huringa ECG infarction myocardial rahi iti ki iti wāhikē i te aratau ST wāhanga ake ki raro ranei, i runga i te wāhi o te infarct rānei, ko T koaro poipoi

whakawhanake te nuinga infarction myocardial i roto i te ana roro maui. Localization o kanga necrosis myocardial kitea e te ahua tohu electrocardiographic āhuatanga o infarction i roto i te ahu tēnā.
