Atrial fibrillation

Ib qho ntawm feem ces yuav tsum arrhythmia nyob rau hauv tib neeg - atrial fibrillation. Nws loj heev yog 0.5% ntawm tag nrho cov pejxeem. Prognostic tseem ceeb ntawm tus kab mob no yog tseem loj. Qhov kuaj pom ntawm atrial fibrillation tsub kom lub neej no ntawm cov neeg mob ob npaug, piv rau cov neeg uas tsis muaj kev ua txhaum conductivity muaj nuj nqi. Lub predominant muaj hnub nyoog ntawm cov neeg uas raug kev txom nyem ib tug mus tas daim ntawv ntawm tus kab mob - cov neeg laus. Paroxysmal atrial fibrillation yog ntau ntau nyob rau hauv cov tub ntxhais hluas.

Ob yam ntaub ntawv ntawm tus kab mob: paroxysmal (paroxysmal) thiab pheej. Tus thawj lub sij hawm ib tug kab mob arrhythmia tawm tsam yog nres rau ntawm lawv tus kheej los yog nrog kev pab los ntawm cov tshuaj. Kev kho mob rau daim ntawv no ntawm tus kab mob no yog raws kev coj kom ua tau thiab ces muaj ib tug ib txwm lub plawv dhia. Pheej atrial fibrillation yuav ua tau ib tug relapse twb arisen ua ntej lawm pathology los yog thawj tsau fibrillation. Nws ntawd kub ntev li xya hnub, thiab nres los ntawm cov tshuaj.

yog vim li cas

Atrial fibrillation tshwm sim tiv thaiv ib tug tom qab ntawm cov kab mob ntawm cov hlab plawv system. Qhov feem ntau heev tus kab mob uas ua rau yus txoj kev loj hlob ntawm lub arrhythmia hais txog coronary mob plawv (50-60% ntawm cov neeg mob), tawg (40-50%), coronary artery bypass grafting (5%), mob heart attack myocardial infarction. Fibrillation feem ntau tshwm sim nyob rau hauv cov neeg uas tsim txom lawv haus dej haus cawv. Nyob rau hauv cov ntaub ntawv no muaj dej cardiomyopathy, uas provokes cov tsos ntawm arrhythmia. Kis kab mob thiab mob ntawm dej-ntsha metabolism thiab pab txhawb kom lub rov tshwm sim ntawm tus kab mob.

txoj kev loj hlob mechanism

Atrial fibrillation muaj tshwm sim nrog cov kev ua txhaum ntawm sab laug atrium ntawm lub plawv. Nyob rau hauv qhov chaw ntawm lub myocardium muaj kev hloov ntawm hluav taws xob pulses hais tias tus active ua arrhythmia. Thaum lub sij hawm atrial fibrillation nres cai disorganization ntawm tag nrho cov hluav taws xob muaj dab (asynchronous, chaotic, cov neeg pluag arousal mob nqaij fibers). Nws tsim nyob rau hauv ib feeb mus rau 700 pulses, uas npog tej pawg me me ntawm fibers, uas cuam tshuam rau kev li qub systolic contraction. tsuas ib feem ntawm tus mem tes yog muaj nyob rau myocardium. Txawm li cas los, nws yog tsim ib tug tachycardia, uas yog tag nrho nrog rau arrhythmia.

cov tsos mob

Atrial fibrillation yog tsiag ntawv los ntawm cov nram qab no cov tsos mob: kev xav ntawm kev cuam tshuam thiab palpitations, tsis xis nyob los yog mob nyob rau hauv lub plawv, tsis muaj zog, kiv taub hau, hauv siab ceev ceev, ua tsis taus pa uas tshwm sim txawm nyob rau hauv tas, qaug zog, uas sau rau ib ntev lub sij hawm.

Nyob rau hauv tej rooj plaub, tus kab mob no yog tsiag ntawv los ntawm kev soj ntsuam daim duab yog erased. Nyob rau hauv cov ntaub ntawv no, cov neeg mob tsis txhob xav qhov raug disruptions ntawm mob ua si, zuag qhia tag nrho noj qab haus huv tsis tau tawg ntawm ib tug tsawg lub plawv dhia. Txawm li cas los, tsis muaj kev kho mob, qhov no hom ntawm arrhythmia tej zaum yuav txuam nrog txoj kev loj hlob ntawm cov teeb meem. Cov no muaj xws kab mob plawv, cerebrovascular kab mob, uas ua rau yus mob stroke, plab hnyuv infarction. Nws yog muaj pov thawj hais tias cov preservation ntawm atrial fibrillation ntau lub xyoo ua rau ib tug txo nyob rau hauv kev txawj ntse ua ub no. Yog li ntawd ua ib qho tseem ceeb diagnostic hom kev kawm, qhov tseem ceeb uas yog cov electrocardiogram. Nws yog qhov no yam ntxwv hloov cai arrhythmia: hauv lub qhaj ntawv ntawm lub P yoj mus rau lub QRS complex pathological yoj kuaj es tsis txhob f, uas muaj ntau loj, me, zoo lawm. Lawv ntev nce mus txog 700 rau ib feeb. Kev kho plawv, thaum tau tebchaws cov kev pauv nrog cog qoob loo yuav muab qhov no mob.
