'Aʻe' ana o ka repolarization kaʻina.

'Aʻe' protsesa repolarization - ka aʻe abnormality o ka mea'ōnaehana mānowai koko'ōnaehana, ma ka pau - ka pathology o ka lawelawe a me ka excitable hapa o ka naau'aʻaʻa. Oia loli i wehewehe aku kuhikuhi concomitant loli ma ka electrocardiogram. Loa pinepine hoike kue repolarization io (a hoonohonoho i contour) niho T i loko o ka mua a me ka lua o ka hae hiki aku ai. ʻO ia mau kiʻi, pu me ka offset lower ST Hoʻohana isolines malama i kēpau aVL a me ka lima a me ka ono precordial hiki aku ai.

Pinepine mau hoailona i ano o dysfunctional kāna hana o ke aloha o ko mākou hopohopo'ōnaehana, oa iaea ooieoeiiaeuiiai cardiomyopathy.

Kēia cardiomyopathy ua hoikea mai oia, e like me ka 'aʻe' ana o ka repolarization kaʻina hana o ka naau Muscle'aʻaʻa (myocardium) i hiki hoʻomaka conduction kāna hana a me ka naau pāpana hope. 'Aʻe' repolarization kaʻina hana hiki e kauoha ae la ia e kekahi pūʻulu nui o ka causative (etiological) kumumea. A pau kēia mau kumumea hui i eha pūʻulu ka nānā 'ana ma luna o na kumu i loko o ka pathophysiology keʻano o ka hanaʻana. Ka mua pūʻulu - maʻi e alakai ai i ka hoʻohuikau 'o ka neuroendocrine rula o ka mea'ōnaehana mānowai koko'ōnaehana, me na maomeka o kāna hana o ka potasiuma hooponopono a me ka catecholamine pae. Ka lua o ka pūʻulu ka loaʻa o nā mea a pau degenerative a me ka hoʻoʻino lesions o ka muscular'aʻaʻa o ka naau. Eia kekahi, hihia hoʻi repolarization kaʻina hana hiki e kena ae e kekahi overload a myocardial hypertrophy. Ka hope pūʻulu ka loaʻa o ka mea kiʻekiʻe kāna hana alakai i ka broadening o QRS luna '(blockade mau lala ventriculonector, WPW maʻi pale).

Ka loa e like me ka 'aʻe' ana o ka repolarization kaʻina e hoʻomōhala ana i like me ka hualoaʻa hypersympathicotonia. Kēia pathology hoike mai ai ia ia iho i loko o kakahiaka kamaliʻi, a ua wehewehe aku e hoonuiia pae o hormones (adrenaline a me ka noradrenaline) pāpālua ma e like me ke kūmau. Eia hou kekahi, 'aʻe' ana o repolarization i loko o ka myocardium hiki e kena ae ole ma ke kiekie pae o kēia mau hormones i loko o ke koko, a ua mahuahua pā lonoaʻili i cardiac'aʻaʻa i catecholamines. E like me ka hopena, i loko o ka maʻamau hōmona pae, he mea piha i hoike lapaʻau kiʻi hypersympathicotonia.

I waena o nā kumu o nā paewaewa ma ka repolarization o ka myocardium, ka nui kaʻana like o nā kēia: coronary naau maʻi, hoʻopōʻino maomeka a me ke kaʻina o nā pae depolarization gmpertrofiya a overvoltage muscular ventricular'aʻaʻa kāna hana i loko o electrolyte kaulike (i pau - kāna hana o ka paʻakai, a potasiuma koena).

A hoʻokaʻawale pūʻulu ninoieo o ole-kekahi kumu. I ka mea, hoʻopōʻino repolarization o ka naau Muscle'aʻaʻa ma keia hihia aohe mea i hiki mua ma ka Pahuhopu kumu. Ma keia hihia,ʻike, a me ka palena pauʻike, 'aʻole e hōʻike mai i kaʻiʻo kumu o ka maʻi.

Oia kāna hana i increasingly, he pono ole i loko o ui kanaka adolescence. Ka hapa nui o kēia mau kāna hana i transient a me ka mai e pono ai lapaau. Eia naʻe, a hiki i ka wa e kaawale aku o ka iapaau ana o kēia mau nā mea maʻi pono a eia iʻano ma ECGʻikepili. Lapaʻau o myocardial repolarization ua kuhikuhi ma muli o ka hoʻopau o ka waiū a hiki i ka causative ololi, i mea, lapaʻau mea etiotropic külana.

Holo nōhie, ka lapaau maupaʻa i ka luna 'medicaments oia hoi o kortikotropnogo hōmona, propranolol, panangina, cocarboxylase a me ka wikamina hoomakaukau. Ma kekahi hihia, i ka iapaau ana o keia maʻi pono OAXA lapaʻau ninaninau o ka hoʻomanawanui.
