Tūkinotanga o te tukanga repolarization.

Tūkinotanga repolarization protsesa - te pīari muri o te pūnaha Cardiovascular, i roto i te ngā - i te māuiuitanga o te wahi conductive me ka hikaka o te kiko ngakau. E āhuatanga taua huringa huringa matua te rere i roto i te hiko-. Nuinga o ngā wā whakakitea repolarization takahi T tōraro (whakaritea i aratau ranei) niho i roto i te ahu paerewa tuatahi, me te tuarua. Ko te taua pikitia, tahi ki te wāhikē raro isolines wāhanga ST kitea i roto i te mata, aVL me ahu manawa tuarima me te tuaono.

E mea pinepine e āhuatanga o disorders aueue o te pūnaha io pukuaroha enei tohu, ie cardiomyopathy mahi.

whakakitea ana tēnei cardiomyopathy te rite te takahi o te tukanga repolarization o te kiko uaua ngakau (myocardium) e taea te kōkiri i disorders āriponga me mahi manawataki ngakau. Ka taea te meinga tukanga repolarization takahi i te rōpū nui o fakatupu (etiological) āhuatanga. ngā enei āhuatanga katoa ki wha ngā rōpū e hāngai ana i runga i ngā noa i roto i te tukanga pathophysiology. Ko te rōpū tuatahi - mate e arahi ki te rangirua o te ture neuroendocrine o te pūnaha Cardiovascular, tae atu i te huarahi o disorders o pāhare pāporo ture me ngā taumata catecholamine. Ko te rōpū tuarua ngā pāpaka degenerative me inflammatory katoa o te kiko uaua o te ngakau. I tua atu, e taea te meinga tukanga repolarization waimaero e te kikī ranei hypertrophy myocardial. Ko te rōpū whakamutunga ngā te disorders tuarua ārahi ki te whakawhānui o QRS matatini (pā manga ventriculonector, WPW syndrome).

Ko te ofatiraa tino noa o te tukanga repolarization whanake rite te hypersympathicotonia hua. faaite tenei māuiuitanga ake i roto i te kōhungahunga me te āhuatanga e nui haere ngā taumata o hormones (Adrenaline me noradrenaline) rererua i rite ki te täkupu. I tua atu, takahi o repolarization i te myocardium Ka taea te meinga e kore e faateiteihia taumata o enei hormones i te toto, a ka nui ake te tūtohutanga ki cardiac kiko ki catecholamines. Ka rite ki te hua, i roto i te taumata taiki noa, i reira he oti hypersympathicotonia pikitia haumanu whakahuatia.

I roto i te pūtake o kōtītiti i te repolarization o te myocardium, te wahi nui rawa o te whai ake: mate ngakau coronary, huarahi waimaero me te raupapa o te wāhanga depolarization gmpertrofiya me overvoltage disorders ventricular kiko uaua i roto i te toenga kawehiko (i roto i te ngā - disorders o te konutai me te konurehu toenga).

Ngā tētahi rōpū motuhake o take kore-motuhake. I roto i te meka, repolarization waimaero o te kiko uaua ngakau i roto i tenei take kahore he aroaro kitea i runga i nga take whāinga. I roto i tenei take, e kore e tātaritanga me te pārōnaki tātaritanga whakakitea nga take nui o te mate.

E piki noa i roto i te iwi taitamariki taiohi taua disorders. Ko te nuinga o enei disorders Are rangitahi me ta koutou e mea e kore hiahia maimoatanga. Heoi, ara i roto i te ngaro o te whakahaere maimoatanga o enei tūroro titau dynamics tamau i roto i ECG raraunga. Kei te matua e hāngai ana maimoatanga o te repolarization myocardial i runga i te whakakorenga o te rongo ki te take pūtake, e ko, maimoatanga he pūāhua etiotropic.

Fele, Kei te maimoatanga te medicaments matatini arā o taiaki, propranolol, panangina, cocarboxylase me te huaora taka kortikotropnogo. I roto i tetahi take, i roto i te maimoatanga o tenei mate titau whakahauanga whakamātautau haumanu o te manawanui.
