Matau poraka peka paihere

Ko te pā o matau paihere peka poraka kurupae - i Hokona kawenga whakararuraru i roto i te ventricles o te ngakau. Te reira i tupu i roto i te 0.2% o te kuao iwi. Ki te tau, i tenei arrhythmia auau piki ki 0.45%. Tenei mate ko te tata tonu puta i roto i te toa hawhe o te taupori.

Ko te take matua e pāngia e te whanaketanga o tenei mate ko te whakaeke ngakau i roto i te wāhanga whakapeka. Iwi o wha tekau nga tau te pā o te waewae matau paihere o tana mārire, he reira kahore hononga ki abnormalities o kiko cardiac. I roto i te tahi atu te wā i te whanaketanga o tenei momo o arrhythmia whakatairanga takawhita (60% o te katoa o te wā). I roto i te wā onge e meinga ai e kōhikohiko congenital (hypoplasia o te wāhanga myocardial tuatahi). Ano, ko te putanga o te kāwanatanga pāngia e te aroaro o hē ngakau: hē ventricular, taiepa Atrial, whāiti te mangai o te uaua tana pukapuka. Thromboembolism o te ipu, me ma'i pūāhua mate pūkahukahu taunutia arata'i ki totoro o te mānawanawa matau, ka taea e tenei whakapataritari i te ahua o arrhythmias.

Ētahi āhuatanga e whai wāhi ki te whanaketanga o tenei huru he cardiomyopathy, uma whētuki puhuki, ahu whakamua Duchenne, hyperkalemia, tuwhena rawa raau (novokainamidom, quinidine, glycosides cardiac), pokanga i runga i tenei okana (ventrikulotomiya poutū), pukupuku cardiac, syphiloma. He tohu haumanu o mate e kua meinga reira oti pā o tika poraka manga paihere. E whakaritea ētahi tūroro i huringa i roto i auscultation: wāwāhi i te tuatahi (iti noa), a ka tuarua i te reo (atu noa).

He hiko-kitea e whai ake tātaritanga paearu e: piki haere te ventricular matatini, tiketike niho R, i He i kitea ai i roto i te tuatahi manawa ahu, serrated R, rite tautuhi i te maui ahu niho e kua he rerekē uara; S aronga discordant, ST.

Matau paihere peka poraka, te maimoatanga o e, rite reira kia titiro ki Kia nui, e kore e rapua tetahi motuhake taka. Te reira i hoki e kore e rapua edokardialnoy whakaongaonga, i roto i te noa te wā kei mea ai i roto i tikanga ki te ārai i roto i te take o ngakau whakaeke. Ki te tika te maimoatanga o mate, e arahi tonu ki te ahua o tenei momo o te arrhythmia. Ko te pā o matau paihere manga poraka kurupae tupu i roto i te iwi o muri ake rōpū, i roto i nei i reira ko kahore organic pāpaka o te cardiac kikokiko kua he āhua pai waitohunga. e kore Tiro taratahi o te arrhythmia taea te haere ki tonu AB AB kōpuku pā.

E ai ki te ako, te takanga tukutahi o enei abnormalities arahi ki te rangirua iti o te kawenga i te atria ki te ventricles. Heoi, te taea ino o te haumanu te akoranga o tenei mate Tuhinga ki whakaiti o ngātere i te pūhui AB. A, no te āpiti i tenei momo o te arrhythmia tika ki takawhita, hoki te tino faingataa tenei mate, riro teitei i raro i enei tikanga lethality. He āhuatanga kino ko te aroaro o cardiomegaly, kore ngakau congestive, wā systolic elongation. Ko te pā o matau paihere peka poraka kurupae, puta ki te papamuri o myocardial infarction, tata kore e haere ki tetahi arrhythmia hāngai ki pōrearea o te pae i roto i te AB. Na reira, e tata kahore taumata tiketike o te tahuti tenei momo o te māuiuitanga. Heoi, ko te aroaro o pōauautanga cardiac nui, kia reira hoki taimaha me te haafifi ratou maimoatanga, e ai kia hauarea.
