Kuphwanya ndondomeko repolarization.

Violation protsesa repolarization - ndi chosayenerera yotsatira ya mapeto a mtima, makamaka - ndi kudwala mbali conductive ndi okonda wa minofu mtima. asinthire yodziwika kusintha kwenikweni concomitant mu electrocardiogram lapansi. Ambiri zambiri akuwonetseredwa kuphwanya repolarization zoipa (kapena anakonza pa mizere) dzino T mu yoyamba ndi yachiwiri kumam'phunzitsa muyezo. Chithunzi thunzi, pamodzi ndi kuchepetsa m'munsi cha ku Switzerland gawo isolines anati mu kutsogolera aVL ndi wachisanu ndi chimodzi kumam'phunzitsa precordial.

Kawirikawiri zizindikiro ndi khalidwe la matenda osokonekera wa mantha dongosolo wachifundo, mwachitsanzo zinchito cardiomyopathy.

cardiomyopathy Izi chidawoneka kuphwanya repolarization ndondomeko ya mtima minofu minofu (myocardium) kuti akhoza kuyambitsa matenda conduction ndi ntchito mtima mungoli. Violation ndondomeko repolarization bwino zimayamba ndi gulu lalikulu la causative (etiological) Zinthu. Mfundo zonsezi ophatikizana m'magulu anayi potengera mfundo wamba mu njira pathophysiology. Woyamba gulu - matenda chopatsa kusokonezeka kwa neuroendocrine lamulo dongosolo mtima, kuphatikizapo njira ya matenda a lamulo potaziyamu ndi milingo catecholamine. Gulu lachiwiri zikuphatikizapo onse zotupa osachiritsika ndi yotupa kwa minofu minofu ya mtima. Komanso, chakhungu repolarization ndondomeko bwino zimayamba ndi zimamuchulukira kapena m'mnyewa wamtima hypertrophy. Gulu chathachi chikuphatikizapo matenda yachiwiri zikubweretsa poonetsa wa QRS zovuta (anatseka misewu nthambi ventriculonector, WPW syndrome).

Kuphwanya ambiri ndondomeko repolarization akufotokozera chifukwa hypersympathicotonia. kudwala kumeneku kumaonekera ana aang'ono ndipo amakhala ndi kuchepetsa mahomoni (zikuwonjezereka masiku ano ndi noradrenaline) kawiri poyerekezera ndi mwakale. Komanso, kuphwanya repolarization mu myocardium akhoza anachititsa osati ndi milingo okwera mahomoni izi mu magazi, ndipo inachuluka kudziwa minofu mtima kuti makatekolamaini. Chifukwa, mu timadzi ta m'thupi wabwinobwino, pali wathunthu anasonyeza matenda chithunzi hypersympathicotonia.

Pakati zimayambitsa monyanyira mu repolarization wa myocardium, ndi gawo lalikulu kwambiri zotsatirazi: matenda a mitima, zimagwirira mkhutu ndi ndondomeko ya gawo depolarization gmpertrofiya ndi overvoltage akulu matenda yamitsempha yamagazi minofu bwino electrolyte (makamaka - matenda a soda ndi bwino potaziyamu).

A gulu osiyana tichipeza zimayambitsa si yeniyeni. Ndipotu, mkhutu repolarization ya mtima minofu minofu Pankhaniyi palibe pamaso kuonekera pa zifukwa cholinga. Pankhaniyi, matenda ndi matenda masiyanidwe silinena zimayambitsa kwambiri matenda.

Matenda oterowo ayamba zofala achinyamata unyamata. Ambiri mwa matenda amenewa ndi kufupika ndipo safuna chithandizo. Komabe, ngakhale sitili pa kasamalidwe chithandizo cha odwala awa amafuna mphamvu zonse mu ECG deta. Chithandizo cha repolarization m'mnyewa wamtima kwenikweni zochokera Kupha kukhudzana ndi chinthu causative, ndiye mankhwala etiotropic khalidwe.

Kwenikweni, mankhwala limapangidwa ndi medicaments zovuta ongokhala timadzi, propranolol, panangina, cocarboxylase ndi vitamini kukonzekera kortikotropnogo. Mulimonsemo, pa chithandizo cha matenda amafuna kuvomerezedwa matenda Kupenda wodwala.
