Frederick's syndrome tau txais nws lub npe nyob rau hauv kev hwm ntawm Belgian physiologist, uas txhais tau tias nws yog ib qho kev sib xyaw ua ke ntawm kev ua tiav transverse (atrioventricular) thaiv thiab atrial fibrillation, nyob rau hauv lwm yam mob - atrial flutter. Kab lus no tham txog Frederick's syndrome: tsev kho mob, kuaj mob, kho tus kab mob.
Mechanism of the Syndrome
Cov txheej txheem ntawm Frederick's syndrome yog raws li hauv qab no: los ntawm lub atria mus rau lub ventricles, lub conduction ntawm impulses kiag li nres; disorderly, chaotic, feem ntau tshwm sim excitation thiab contraction ntawm ib co pab pawg neeg ntawm atrial nqaij fibers. Cov ventricles zoo siab los ntawm lub tshuab pacemaker nyob ntawm lub atrioventricular hlws ris los yog nyob rau hauv lub conduction system.
Caus ntawm Frederick's Syndrome
Tus kab mob no tuaj yeem tshwm sim tom qab mob hnyav hauv lub plawv, uas feem ntau nrog cov txheej txheem ntawm o, sclerotia lossis degeneration hauv myocardium. Cov txheej txheem no suav nrog, piv txwv li, kab mob plawv ischemic, feem ntau nyob rau hauv daim ntawv mob ntev, mob plawv nres.myocardial infarction, myocarditis, cardiomyopathy, angina thiab lwm yam. Nrog rau cov kab mob zoo li no, cov txheej txheem sclerotic tsim nyob rau hauv lub plawv cov leeg, vim tias cov ntaub so ntswg loj hlob tsis tsim nyog, uas hloov cov cell qub uas paub txog lub cev thiab muaj peev xwm ua tau hluav taws xob impulses. Yog li ntawd, conduction yog cuam tshuam thiab blockade tshwm sim.
daim cardiogram qhia dab tsi
Ib qho electrocardiogram feem ntau raug txiav txim kom paub meej tias tus neeg mob nrog Frederick's syndrome. Ntxiv mus, nws yog qhov zoo dua los ua qhov kev kawm thaum nruab hnub txhawm rau ntsuas lub plawv dhia ntawm lub sijhawm sib txawv thiab sau cov ntaub ntawv tiav ntau dua.
Yog tias muaj kab mob ntawm ECG, nthwv dej ntawm atrial fibrillation lossis flutter raug kaw, thaum tus neeg noj qab haus huv yuav tsum muaj cov hniav. Lub ventricular atherosclerosis ua nodal los yog idioventricular, thiab feem ntau tsis-sinus ectopic.
R-R ntu ntu tas li thiab muaj lub suab tsis tu ncua. Tus naj npawb ntawm contractions ntawm lub ventricles yog sau nyob rau hauv ib tug npaum li cas tsis pub tshaj 50-60 zaug ib feeb. Lub ventricular complexes feem ntau dilated thiab deformed.
Kev kho mob tshwm sim thiab cov tsos mob
Tsuas yog nrog kev pab ntawm electrocardiogram tuaj yeem lees paub tseeb tias Frederick's syndrome hauv tus neeg mob. Lub tsev kho mob uas nrog nws nyob rau hauv lub neej txhua hnub, uas ib tug neeg yuav tsum tau xyuam xim rau, yog ib tug tsis tshua muaj, tab sis raug mem tes nrog lub plawv dhia ntawm tsawg kawg yog 30 thiab tsis ntau tshaj 60 zaug ib feeb. Lub plawv dhia poob vim tias kev siv lub peev xwm txo qislub siab. Nyob rau hauv lem, cov saum toj no ua rau oxygen starvation ntawm lub hlwb.
Cov neeg mob feem ntau yws yws ntawm qhov tsis muaj zog, kiv taub hau, ua tsis taus pa, tsis zoo ntawm kev noj qab haus huv txawm tias tom qab ua haujlwm lub cev me ntsis. Yog hais tias ib tug neeg tsis xyuam xim rau Frederick's syndrome, cov tsos mob hnyav zuj zus tuaj, lub plawv nres ntev li 5-7 vib nas this yuav tshwm sim. Tsis tas li ntawd, tsis nco qab vim ventricular tachycardia yog ua tau.
Kev kho mob
Ntau zuj zus, cov kws kho mob pom zoo tias tib txoj kev kho kom raug rau kev kho mob ntawm Frederick's syndrome yog kev cog qoob loo ntawm cov neeg mob ntshav qab zib. Ntawd yog, ib qho hluav taws xob tau muab tso rau hauv lub ventricle, uas ua rau muaj kev cuam tshuam thiab ua rau lub zog ua rau myocardial contraction.
Qhov zaus ntawm kev sib cog lus yog teem ua ntej nyob ntawm tus neeg mob tus mob thiab lub cev ua si.
Ntxiv nrog rau pacing, anticholinergics kuj tseem siv. Cov no yog cov tshuaj tshwj xeeb, piv txwv li, atropine. Txawm li cas los xij, tsis ntev los no lawv cov kev siv tau raug tso tseg vim muaj ntau yam kev mob tshwm sim, suav nrog kev cuam tshuam tsis zoo rau tus neeg mob lub siab, piv txwv li, kev loj hlob ntawm atropine psychosis.
Feem ntau, kev kho mob nyob ntawm hemodynamic stability thiab ua rau atrioventricular block.
Yog li, Frederick's syndrome yog qhov mob hnyav heev ntawm cov leeg nqaij hauv lub plawv, tus cwj pwm los ntawm kev ua tiav transverse blockade ua ke nrog atrial fibrillation.
Txawm li cas los xij, tam sim no nrog txoj cai thiab sijhawmib zaug kuaj pom, qhov tshwm sim no kho tau, tom qab ntawd tus neeg mob tuaj yeem rov qab mus rau qhov qub thiab ua rau lub neej zoo li qub.
