Ukuphulwa mitral valve umsebenzi

Valve mitral liyisici esibalulekile kakhulu ohlelweni womuntu senhliziyo nemithambo yegazi. Ngakho-ke, iyiphi ukuphambuka e isebenze yayo nomthelela omubi kakhulu empilweni yethu nenhlalakahle. Sinikeza ukuthola mayelana ukuqokwa valve mitral, kanye ukwephulwa emsebenzini yayo, izimpawu zabo kanye nemiphumela. Ngizothanda futhi ukuba uqaphele ukuthi, ngenxa yanoma yisiphi izimpawu yokwephula umsebenzi "imininingwane" we imisipha yenhliziyo kuphoqelekile ukuvakashela wenhliziyo, ezosiza eBandleni lokuqala uphethwe esiteji izifo kunokwenzeka.

Umsebenzi we-valve mitral kumuntu senhliziyo esilimele

Valve kuyinto ichopho kwezicubu ekhethekile zezinzwa futhi itholakala ohlangothini lwesobunxele kwenhliziyo yomuntu. It kuvimbela ukugeleza reverse igazi ngokufaka ATRIUM kwesokunxele kusukela i-ventricle engakwesobunxele ngesikhathi ukusikwa okuqhubekayo myocardium. Lapho inhliziyo eyikho engumqemane, valve by odlula lemali edingekayo wegazi ivaliwe. Uma enezinto sebeqala ukuxhumanisa up uvalwe, inhliziyo uyakhula begodu hypertrophy okwagcina kuholela ukwephula emsebenzini wakhe. The njalo kunazo ihlangabezane kule izifo ensimini ezifana mitral umphini uphawu (noma prolapse) futhi ukuhluleka kwawo. Sinikeza sibhekisise ngalinye zalokhu kwephula umthetho emsebenzini imisipha yenhliziyo.

prolapse

Mitral valve prolapse, okuyinto is phetho uphawu, kuvamile. Lesi sifo ngokuvamile asymptomatic. Nokho, kwenzeka ukuthi kuhambisana iphika, ubuhlungu futhi palpitation zenhliziyo.

Kunezizathu eziningana ukuthi kwandisa ingozi yokungenwa prolapse. Laba bachazwa ngezansi izizathu.

1. UPawulu. In amadoda, lesi sifo itholwa kakhulu izikhathi ezingaphezu engxenyeni fair lesintu.
2. Ubudala. Ingozi yokuba mitral prolapse inyuka kakhulu ngeminyaka.
3. umlando womndeni. Uma othile emkhayeni wakho wahlushwa isifo esifanayo, ke kukhulisa ematfuba lapho ivela khona futhi.
4. kwezinso Bezakhiwe (azalwa naso noma ushintsho atholwe).

esingamahlalakhona mitral

Kukhona izinhlobo ezimbili mitral valve: oyingozi futhi ezingalapheki. kuphakama Eyokuqala ekubhujisweni imisipha papillary, imisebenzi kuhlinzwa, umsipha uyadabuka ukulele kubangelwa isilethikusebenza, endocarditis infective, futhi ukulimala ahlukahlukene. Ifomu okungamahlalakhona kungase kube umphumela rheumatism senhliziyo esilimele, izifo letindzala, izifo lezinceku noma azalwa naso, izimila nezinye izimo.

Isigaba elula yalesi sifo umphini mitral esingamahlalakhona 1 degree. Ukubonakaliswa eyinhloko lesi sifo ukubukeka nokububula inhliziyo. Njengomthetho, iziguli ukuphila okumatasa futhi abanalo izikhalazo. Lapho mitral esingamahlalakhona wesibili noma degree lesithathu kuya umsindo inhliziyo kufushane ungeze ukuphefumula futhi inhliziyo palpitations lapho uvivinya umzimba. I esiyingozi kakhulu ukuphila komuntu izigaba 4th futhi 5, lapho kuqale nokuqala ukwenzeka izinguquko esiwohlozayo e imisipha yenhliziyo, futhi ngenxa yalokho yini izifo kwegazi siba sibi ukusebenza kwezinye izinhlaka.
