Dilatation wa atrium kumanzere

Chifukwa ambiri, amene akufotokozera dilatation wa atrium chatsalira systolic kukanika. ndondomeko imeneyi yafotokozedwera kuchepetsa kumanzere yamitsempha yamagazi M'mimbamo kuponya kwa magazi mu msempha. Chifukwa cha dilation wa atrium kumanzere amachititsa kukula kwa yotsiriza systolic buku la ventricle kumanzere. Kukachitika kuti zimenezi zingachitike compensatory amakhala insolvent, kungakhale sekondale venous m'mapapo mwanga oopsa. Matenda dilatation molumikizana ndi m'mapapo mwanga wolumikizira oopsa ukuwonjezeka yamitsempha yamagazi bwino katundu, sitiroko mphamvu zimachepa. Kuwonjezera kuthamanga diastolic wa atrium chabwino ndi ventricle amachititsa venous kuchulukana.

mtima dilation ndi kuwonjezeka okwana buku thupi. Myocardium anatambasula woonda, koma ngati mukubwera hypertrophy, njira awiriwa kuletsa mzake kunja. Pappilyarnye M'mimbamo komanso anatambasula minofu minofu trabecular kwambiri flattened. Dilatation wa atrium kumanzere amachititsa yowonjezera orifice atrioventricular, zomwe zina kumayambitsa matenda zinchito. The ventricle kumanzere limayamba ndi kutambasula invaginates kuti patsekeke bwino yamitsempha yamagazi, umene buku ake amachepetsa.

Dilatation wa atrium anachoka njira compensatory atenge mbali mofanana zipangizo mu mtima wathanzi. Ngati mtima woipa alibe mphamvu zokwanira kuti akakokoloredwe kuchuluka kwa magazi, ndi kukula kutalika ulusi, izo zimakhala wokhoza kuchita ntchito. Komabe, izi amachepetsa mphamvu yopuma wa myocardium ndi kuwonjezeka kuchuluka kwa ntchito ndi pakufunikira oxygen. Anthu dilatation ayenera kutsatira chithandizo wofatsa, monga aliyense ngakhale ntchito zing'onozing'ono zachitika likuvutika m'malo a nkhondo mtima. Dilatation ndi wamba syndrome ndi chifukwa mtima kulephera. Matendawa akhoza kukhala matenda ndi poizoni chikhalidwe. Nthawi zambiri chifukwa dilation ndi mowa mtima kuwonongeka. Chifukwa chake monga autoimmune ndi matenda neuromuscular, komanso kwa mayitirokondiriyoni, endocrine ndi matenda kagayidwe kachakudya mu mtima.

Monga ulamuliro, dilatation akufotokozera ali aang'ono ambiri mwa anthu. mawonetseredwe chipatala ali chimaonetsera chaphindu mtima, angina onyenga, mtima arrhythmias, angina, thromboembolism. chipatala matenda si yeniyeni. Wodwala mwadzidzidzi kufa ndi matenda mwapang'onopang'ono mtima kapena chifukwa arrhythmia. Pamene matenda kawirikawiri wapezeka systolic kudandaula ndi tricuspid ndi mitral insufficiency. Palinso edematous syndrome ndi kutupa kwa mitsempha khosi.

The njira yaikulu matenda ndi echocardiography ndi scintigraphy. Infomeshoni zothandiza mukhoza kugwiritsa ntchito mayesero nkhawa ndi matenda masiyanidwe.

Mankhwalawa dilatation likukhudza ndendende chithandizo cha ku kulephera mtima, popeza mankhwala causal zimatheka ndi etiologies kudziwika. Amalangiza kuchepetsa kudya madzimadzi, okwanira
thupi, kudziletsa diuresis. Izo kutiletsa phwando ngakhale
Mlingo ka mowa. Ndi chitukuko cha cachexia mtima n'kofunika kwambiri michere kuti thandizo zakudya. Kuchipatala makamaka beta-blockers ntchito. Zikusonyeza ntchito thiazide ndi kuzungulira okodzetsa, mmene ulamuliro optional wa diuresis. Mothandizana ndi muzikangana okodzetsa aldosterone ntchito.
