Ventricular fibrillation yog txheej txheem uas tshwm sim los ntawm qhov tshwm sim ntawm tachyarrhythmia. Qhov no qhia tau hais tias ib tug neeg muaj lub suab tsis tu ncua thiab nquag - mus txog 600 ib feeb. Pathology yog nrog los ntawm kev poob siab, tsis nco qab, pallor, discoloration ntawm daim tawv nqaij, ua pa hnyav, convulsions, thiab feem ntau qhov no ua rau coronary tuag. Txhawm rau tsim qhov kev kuaj mob no, nws yog ib qho tsim nyog los sau cov ntaub ntawv kho mob thiab electrocardiographic txog tus neeg mob. Thaum soj ntsuam qhov tshwm sim, koj yuav tsum ua qhov defibrillation tam sim ntawd, nrog rau kev kho mob plawv.

Kev piav qhia

Lub cim tseem ceeb ntawm ventricular fibrillation yog kev ua haujlwm ntawm myocardial. Cov txheej txheem yog nrog los ntawm kev cog lus ntawm lub plawv nrog ntau zaus ntawm 500-600 ib feeb. Nws yog ua ntej los ntawm flutter, uas qhov taw qhia yog 200-300 ib feeb.

Nws yuav tsum tau muab sau tseg tias thaum soj ntsuam fibrillation, yog tias tsis pab nyob rau hauv 5-7 feeb, tus neeg ntawd yuav tuag. Ib tug Fabkistus kws kho mob hu cov txheej txheem no "delusions ntawm lub plawv." Qhov no yog vim lub fact tias cov nqaij ntshiv nyob rau hauv lub cev cog lus chaotically, nyob rau hauv tsis muaj txoj kev ua raws li ib txwm atherosclerosis. Vim li no, lub plawv tsis tuaj yeem ua nws txoj haujlwm tseem ceeb. Lub paj hlwb thiab myocardium tsis tau txais cov as-ham thiab oxygen, vim tias lub plawv tsis ua haujlwm tseem ceeb tshwm sim.

Anatomical ua rau tshwm sim

Nws yog ib qho tseem ceeb los xav txog qhov ua rau ventricular fibrillation. Raws li hais saum toj no, flutter precedes no phenomenon. Yog tias koj tsis quav ntsej ob txoj kev, ces ib tug neeg yuav ntsib ventricular asystole. Qhov no yog ib tug pathology nyob rau hauv uas contraction tsis tshwm sim. Hauv qhov no, nws yuav nyuaj rau tus neeg mob ua txhua yam los pab. Fibrillation tsis tso ntshav. Qhov no ua rau kom txo qis, lub hlwb pib tshaib plab thiab tuag. Txhawm rau tiv thaiv qhov xwm txheej zoo li no, koj yuav tsum paub qhov laj thawj ntawm qhov tshwm sim.

txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua rau mob fibrillation thiab flutter ntawm lub ventricles, nws yuav tsum tau ua tib zoo saib xyuas lub cev ntawm lub plawv nws tus kheej. Nws muaj plaub chav. Muaj ob lub ventricles thiab ob lub atria. Vim lub impulses uas lub paj hlwb xa, lub plawv ua hauj lwm rhythmically thiab muab cov ntshav ncig uas tsim nyog rau lub neej. Sai li cov teeb liab cuam tshuam los yog txoj kev uas lawv pom tau hloov, tus neeg muaj qhov ua tsis tiav. Rau cov tsos mob ntawm fibrillation, nws yog ib qho tsim nyog kom lub impulse, es tsis txhob ntawm nws ib txwm txoj kev los ntawm lub hlwb mus rau lub plawv, pib ua ib ncig. Vim li no, myocardiumshrinks random. Lub sijhawm no, cov leeg tsis so. Hauv ob peb feeb, nws nres ua haujlwm tsis zoo.

Txoj kev sib cav

Feem ntau, cov txheej txheem zoo li no tshwm sim los ntawm kev ua haujlwm tsis zoo ntawm lub atrioventricular node. impulses hla nws. Thaum lub sijhawm caws pliav tshwm sim nrog cov leeg hauv lub plawv, lossis muaj qhov cuam tshuam vim qhov tsis tuaj yeem txais lub teeb liab, thawj cov tsos mob tshwm sim hauv ib teev.

Nws yuav tsum tau muab sau tseg tias hauv cov neeg uas tuag vim qhov tshwm sim no, cov ntshav txhaws tau pom nyob rau hauv cov hlab ntsha. Qhov no yog qhov ua rau tuag.

Yog tias peb sib piv flutter thiab ventricular fibrillation, tom qab ntawd thawj qhov kev tshwm sim, qhov kev sib tshuam sib dhos yog pom ntau dua lossis tsawg dua. Thiab nrog rau qhov thib ob - lub voj voog ntawm kev txais ntawm impulses yog tsis xwm yeem. Nws yuav tsum raug sau tseg tias kev ua haujlwm ntawm lub plawv hauv ob qho tib si tsis muaj txiaj ntsig. Feem ntau, xws li pathologies tshwm sim hauv cov neeg uas tau raug mob plawv nres. Ntawm lub tshuab electrocardiogram, cov neeg mob no muaj Q nthwv dej, qhov kev xaiv no qhia tau hais tias qhov kev hloov pauv loj tshaj plaws tau tshwm sim hauv lub plawv, uas ua rau pom kev tuag arrhythmias hauv ib tus neeg.

Cov neeg mob uas muaj kev ua haujlwm tsis zoo ntawm hom electrophysiological yuav tsum tau kuaj xyuas tsis tu ncua los ntawm kws kho mob, txawm hais tias mob plawv tsis tau kuaj pom nrog cov xwm txheej zoo li no. Qhov no tuaj yeem ua rau ventricular fibrillation. Tus neeg mob ECG qhia tau tias QT lub sijhawm thiab kuaj pom tias muaj tachycardia.

Kev pheej hmoo yog cov neeg sivtshuaj. Tus kws kho plawv feem ntau yuav tsum tau kuaj xyuas los ntawm cov neeg uas muaj lub plawv nres, cuam tshuam cov dej-electrolyte metabolism hauv lub cev, puas myocardium. Cov neeg mob uas muaj kab mob hauv lub plawv, ischemia, cardiomyopathy, thiab malformation yuav tsum ceev faj. Feem ntau, qhov no syndrome yog tshwm sim los ntawm kev mob penultimate. Thaum ua qhov kev tawm dag zog lub cev muaj zog tshaj plaws, feem ntau nws yog tus uas provokes fibrillation thiab, vim li ntawd, kev tuag hauv cov tub ntxhais hluas.

Symptomatics

thawj qhov tshwm sim ntawm atrial thiab ventricular fibrillation yog qhov ua haujlwm tas li, qhov ua rau nyuaj rau kev txiav txim siab thaum kuaj mob. Lawv tshwm sim los ntawm extrasystole lossis tachycardia. Cov theem no, uas tshwm sim los ntawm kev qaug zog, tsis yog qhov tseem ceeb, vim tias cov ntshav tsis cuam tshuam.

Nrog rau kev txhim kho ntxiv ntawm qhov tshwm sim, tsis tsuas yog poob ntawm kev nco qab tshwm sim, tab sis kuj convulsions. Qhov no yog vim lub fact tias cov nyhuv twj tso kua mis nyob rau hauv lub plawv tsis ua hauj lwm nyob rau hauv ib tug neeg. Yog tias tus neeg mob tsis tau txais kev pab hauv lub sijhawm, cov ntshav ncig yuav nres, thiab kev kho mob tuag. Cov theem no twb pom tias nyuaj.

Cov tsos mob yuav muaj teeb meem nrog kev nkag siab ntawm lub ntiaj teb, lub plawv tsis muaj zog, tswj tsis tau cov quav thiab tso zis, tsis muaj cov tub ntxhais kawm txav, lawv qhov dilation thiab xim xiav rau ntawm daim tawv nqaij.

Diagnosis

Nws yuav tsum tau muab sau tseg tias qhov tseem ceeb tshaj plaws ntawm qhov tshwm sim ntawm ventricular fibrillation yog qhov ua tsis taus pa thiab pulsation hauv cov hlab ntsha. Yog tias tus neeg tsis tau txais kev pab hauv 5 feeb,Tom qab ntawd cov kev hloov pauv pathological yuav tshwm sim hauv lub hlwb, nrog rau kev mob ntawm lub paj hlwb thiab lwm yam kabmob sab hauv.

ECG nyeem yuav tsum tau siv los ua qhov kev kuaj mob. Tom qab tus neeg mob tau raug tshem tawm ntawm qhov mob hnyav, ntau yam kev kuaj mob yuav tsum tau ua. Qhov no yuav pab nrhiav pom qhov tshwm sim ntawm qhov tshwm sim.

xeem ntxiv

Yuav tsum tau saib xyuas lub plawv. Ua tsaug rau qhov no, ventricular fibrillation tuaj yeem kuaj pom. Nyob rau ntawm ECG, kev ua haujlwm sib luag pom pom, nrog rau kev tsis txaus ntseeg hauv kev ua haujlwm ntawm lub plawv. Nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas qhov muaj magnesium, sodium, thiab tseem xyuas lub xeev cov tshuaj hormones uas cuam tshuam rau myocardium. Yuav kom nkag siab qhov ntev ntawm lub plawv thiab cov hlab ntsha loj, nws yog ib qho tsim nyog yuav tsum tau x-ray ntawm lub hauv siab cheeb tsam. Koj tus kws kho mob tuaj yeem xaj echocardiogram. Ua tsaug rau nws, cov teeb meem valve, txhua yam teeb meem nrog kev cog lus, thiab lwm yam yog pom tau yooj yim. Hauv qhov tsawg thiab hnyav, MRI lossis CT tau ua.

Kev pab ib zaug

Hauv ventricular fibrillation, kev kho mob yog qhov tseem ceeb heev. Koj yuav tsum muaj peev xwm muab kev saib xyuas xwm txheej ceev hauv lub sijhawm luv tshaj plaws, txij li cov teeb meem ntawm kev ua haujlwm ntawm lub plawv tuaj yeem ua rau tuag hauv ib lub vib nas this. Rhythm tsis tuaj yeem rov qab los ntawm nws tus kheej. Qhov zoo tshaj plaws, yuav tsum ua kom muaj kev kub ntxhov thaum muaj xwm txheej ceev, tab sis thaum tsis muaj cov cuab yeej siv, yuav tsum tau ua ib qho nyuaj rau lub hauv siab. Qhov no yuav tshem tawm qhov tshwm sim uas tau tshwm sim.

Yog tias qhov arrhythmia tseem nyob, lub plawv massage thiabua pa ua pa. Txhawm rau ua kom resuscitation yam tsis muaj cov cuab yeej tsim nyog, koj yuav tsum muab tus neeg mob tso rau ntawm nws nraub qaum, qaij nws lub taub hau rov qab. Lub puab tsaig yuav tsum tau thawb mus rau pem hauv ntej kom huab cua tuaj yeem nkag mus rau hauv lub ntsws. Yog tias tus neeg raug tsim txom tsis ua pa, yuav tsum tau ua pa tawm dag zog. Nws zaus yog mus txog 12 txhaj tshuaj txhua feeb. Thaum ua lub plawv tsis ncaj ncees lawm, koj yuav tsum ua kom txog li 100 clicks hauv 60 vib nas this. Nyob rau hauv cov xwm txheej uas ib tug neeg sim coj tus neeg mob mus rau lub neej ntawm nws tus kheej, 2 txhaj tshuaj thiab 15 lub siab ntawm lub hauv siab phab ntsa yuav tsum ua. Qhov no yuav yog qhov zoo tshaj plaws los pab. Yog tias muaj ob tus neeg, qhov piv ntawm 1 txog 5 tuaj yeem siv.
