Ntau tus tau hnov tias muaj tus kab mob no - mitral valve prolapse. Tab sis tsis yog txhua tus paub tias lub valve nyob qhov twg, qhov mob no txaus ntshai npaum li cas thaum lub cev tawm dag zog. Hauv qhov no, cov tub ntxhais hluas feem ntau nyiam cov hauv qab no: yog tias muaj mitral valve prolapse, lawv puas raug coj mus rau tub rog.
Nws nyob qhov twg?
Lub mitral valve nyob nruab nrab ntawm sab laug atrium thiab sab xis ventricle. Nws muaj ob lub valve uas qhib thaum lub sij hawm contractions ntawm sab laug ventricle. Oxygenated ntshav yog thawb los ntawm txoj cai atrium mus rau sab laug ventricle, los ntawm qhov uas nws ces nqa oxygen mus rau lwm yam kabmob. Lub mitral valve txwv tsis pub cov ntshav ntws rov qab mus rau sab laug ventricle.
Dab tsi yog mitral valve prolapse?
Lub sijhawm ua haujlwm, lub valve flaps haum snugly rau ib leeg thiab kaw vim qhov tseeb tias lub valve nruj txaus. Qee zaum nws yog me ntsis ncab, yog li nws tsis tuaj yeem kaw qhov nkag mus rau sab laug ventricle. Vim li ntawd, cov ntshavmuab pov rov qab rau hauv plab. Hauv cov tshuaj, tus kab mob no yog hu ua PMK. Muaj peb theem ntawm tus kab mob, uas nyob ntawm qhov degree ntawm deflection ntawm li qub:
- I degree - qhov mob hnyav tshaj plaws, thaum tus kab mob tshwm sim asymptomatically, tus neeg yuav tsis paub txog MVP;
- II degree - valve deflection yog qhov tseem ceeb dua, tuaj yeem ua rau mob hauv lub plawv nrog cov tshuaj tiv thaiv autonomic, kiv taub hau, pre-syncope thiab fainting, tab sis tsis xav tau kev kho mob;
- III degree - qhov loj ntawm cov ntshav rov qab yog qhov tseem ceeb, yuav tsum muaj kev phais mob los kho qhov ntws.
Yog koj muaj mitral valve prolapse, koj puas koom nrog pab tub rog?
Yog tus neeg muaj MVP ntawm I-II degree, tus kab mob tsis tas yuav kho. Feem ntau nws tshwm sim yam tsis muaj tsos mob. Lub xub ntiag ntawm prolapse tsuas yog txiav txim tau los ntawm echocardiography. Nyob rau hauv tus txheej txheem ntawm kev kuaj mob, nws muaj peev xwm txiav txim siab lub degree ntawm sagging, tus nqi ntawm rov qab ntws thiab muaj concomitant mob. Visually, prolapse tuaj yeem kuaj pom tsuas yog nrog cov ntshav muaj zog reflux mus rau sab laug ventricle thaum mloog lub plawv dhia. Nyob rau hauv cov ntaub ntawv no, mos systolic yws raug kaw. Yog li ntawd, lo lus nug ntawm seb puas muaj mitral valve prolapse, seb lawv puas raug coj mus rau tub rog, unambiguously "yog" tuaj yeem teb tau thaum tus kab mob tsis tshwm sim nws tus kheej (theem I-II). Nyob rau hauv cov ntaub ntawv no, tus kab mob no tsis cuam tshuam rau lub cev kev ua si, ib tug active txoj kev ua neej. Hauv lwm qhov xwm txheej, qhov xaus ntawm tus kws kho plawv yog xav tau.
Yuav kho PMK li cas?
Ntawm thawj thiabtheem ob ntawm kev kho mob tsis tas yuav tsum tau. Yog tias muaj cov tshuaj tiv thaiv vegetative, kiv taub hau, mob hauv cheeb tsam ntawm lub plawv, tshwj xeeb tshaj yog thaum lub cev tawm dag zog, kev kho mob muaj nyob rau hauv kev tshem tawm cov kev tshwm sim. Kev phais mob yog ua nrog qib thib peb MVP, thaum cov ntshav muab pov rov qab rau hauv cov kwj muaj zog, ua rau mob plawv tsis ua haujlwm. Hauv qhov xwm txheej hnyav, lub valve tau hloov nrog cov khoom siv dag zog, tab sis tom kawg muaj lub neej kev pab cuam tsawg: kwv yees li 15 xyoo. Thaum hnav, nws yuav tsum tau hloov dua. Feem ntau, tus kab mob no tau kuaj pom hauv cov tub ntxhais hluas thaum lub sijhawm loj hlob, thaum lub plawv tsis muaj sijhawm los tsim kom sai. Qhov no yog thawj mitral valve prolapse. Hauv qhov no, cov lus nug ntawm seb puas muaj mitral valve prolapse, txawm tias lawv raug coj mus rau tub rog, koj tuaj yeem teb "yog", tab sis tsuas yog nrog thawj qib ntawm MVP.
