Key Difference – AFIB vs VFIB vs SVT
Cov tsos mob ntawm lub plawv dhia yog hu ua arrhythmias. Cov xwm txheej uas yuav tau tham hauv tsab xov xwm no yog ob peb ntau yam ntawm arrhythmias uas nws pathogenesis tshwm sim los ntawm qhov tsis xws luag hauv kev ua haujlwm ntawm lub plawv. Atrial fibrillation (AFIB) yog ib qho mob arrhythmia uas nws tshwm sim hauv cov neeg laus dua 75 xyoo. Ventricular fibrillation (VFIB) yog qhov ceev heev thiab tsis xwm yeem ventricular activation uas tsis muaj kev siv tshuab hu ua. Sustained ventricular tachycardia (SVT) feem ntau tshwm sim los ntawm qhov muaj cov mem tes siab heev uas yog nyob rau hauv 120-220 neeg ntaus / min. Nyob rau hauv fibrillations, contractions ntawm lub plawv cov leeg yog uncoordinated thiab irregular, thiab lawv tshwm sim nyob rau hauv ceev ceev. Tab sis nyob rau hauv tachycardia, txawm hais tias cov contractions tshwm sim nyob rau hauv ib tug ceev npaum li cas lawv yog zoo sib koom tes. Qhov no yog qhov sib txawv tseem ceeb ntawm AFIB thiab VFIB thiab SVT.
AFIB yog dab tsi?
Atrial fibrillation yog ib qho mob arrhythmia uas nws qhov tshwm sim muaj ntau rau cov neeg laus dua 75 xyoo. Cov tub ntxhais hluas muaj feem yuav raug cuam tshuam los ntawm daim ntawv paroxysmal ntawm tus kab mob. P nthwv dej tsis muaj nyob hauv ECG thiab muaj qhov tsis sib xws QRS complexes.

Tshuaj Kho Mob
- Pom pom thawj zaug atrial fibrillation
- Paroxysmal atrial fibrillation - fibrillation nres tsis pub dhau xya hnub txij li pib
- Persistent atrial fibrillation - xav kom cardioversion nres
- Permanent atrial fibrillation - tsis muaj qhov tshwm sim lossis ua rau muaj kev cuam tshuam

Kev tswj hwm
- Kev siv tshuaj tiv thaiv arrhythmic los tswj tus nqi ventricular
- Cardioversion nrog lossis tsis siv cov tshuaj tiv thaiv coagulants
Ob lub tswv yim tseem ceeb muaj rau kev tswj hwm lub sijhawm ntev ntawm atrial fibrillation.
Txoj kev tswj hwm tus nqi siv cov tshuaj tiv thaiv hauv qhov ncauj nrog rau AV nodal cov neeg ua haujlwm qeeb los tswj tus nqi uas lub plawv cog lus. Antiarrhythmic tshuaj ua ke nrog cardioversion thiab qhov ncauj anticoagulants yog siv nyob rau hauv lub atherosclerosis tswj lub tswv yim.
VFIB yog dab tsi?
Kev ua kom lub ventricular nrawm heev thiab tsis xwm yeem uas tsis muaj kev siv tshuab yog hu ua ventricular fibrillation (VFIB). Tus neeg mob yuav pulseless thiab tsis nco qab. Kev ua pa kuj tso tseg nyob rau qee kis.
Nyob hauv ECG, cov txheej txheem tsim tau zoo tsis tuaj thiab cov nthwv dej tsis zoo. Kev nrawm nrawm kuj tuaj yeem pom nyob rau hauv tus mob no. Ventricular fibrillation feem ntau provoked los ntawm ectopic cardiac beats.
Yog tias qhov fibrillation tshwm sim hauv ob hnub los ntawm kev mob myocardial infarction, kev kho mob tsis tsim nyog. Tab sis yog tias qhov fibrillation tsis cuam tshuam nrog ib qho myocardial infarctions, txoj hauv kev tau txais rov tshwm sim ntawm atrial fibrillation yog qhov siab heev. Feem coob ntawm cov neeg mob tuag vim mob plawv nres.

Kev tswj hwm
- hluav taws xob defibrillation
- Kev txhawb nqa lub plawv thiab qib siab
- Kev hloov pauv ntawm ib qho kev cog lus cardioverter-defibrilator
SVT yog dab tsi?
Sustained ventricular tachycardia (SVT) feem ntau yog tshwm sim los ntawm qhov muaj cov mem tes siab heev uas yog nyob rau hauv 120-220 neeg ntaus / min ntau.
Tshuaj Kho Mob
- kiv taub hau
- Hypotension
- Syncope
- Kev mob plawv
- Thaum lub sijhawm auscultation txawv txav hauv lub plawv, lub suab xws li kev siv zog sib txawv ntawm thawj lub siab lub suab tuaj yeem pom.
ECG qhia tau hais tias lub plawv dhia ceev ceev nrog QRS complexes. Qee zaum kuj tseem tuaj yeem soj ntsuam P nthwv dej.
Daim duab 03: SVT
Kev tswj hwm
Kev kho mob ceev yuav tsum tau nyob ntawm seb tus neeg mob hemodynamic li cas. Nyob rau hauv tej yam kev mob xws li pulmonary edema thiab hypotension qhov twg tus neeg mob yog hemodynamically compromised, DC cardioversion yog tsim nyog los stabilize tus neeg mob. Rau cov neeg mob uas hemodynamically ruaj khov, cov tshuaj infusions ntawm chav kawm I lossis amiodarone feem ntau yog siv. Yog tias kev kho mob tsis ua tiav qhov xav tau, DC hloov dua siab tshiab yuav tsum tau siv kom tsis txhob muaj qhov tshwm sim tuag taus.
Qhov Zoo sib xws ntawm AFIB thiab VFIB thiab SVT yog dab tsi?
- Nyob rau hauv tag nrho peb yam xwm txheej yog qhov txawv txav ntawm lub plawv dhia.
- Qhov tsis xws luag hauv kev coj ua ntawm lub plawv yog qhov laj thawj tseem ceeb rau cov kab mob no.

Summary – AFIB vs VFIB vs SVT
Atrial fibrillation yog ib qho mob arrhythmia uas nws qhov tshwm sim muaj ntau rau cov neeg laus dua 75 xyoo. Kev ua kom sai heev thiab tsis xwm yeem ventricular yam tsis muaj kev siv tshuab yog hu ua ventricular fibrillation. SVT lossis sustained ventricular tachycardia feem ntau tshwm sim los ntawm qhov muaj cov mem tes siab heev uas yog nyob rau hauv 120-220 neeg ntaus / min. Hauv tachycardias, cov contractions zoo sib koom ua ke tab sis tshwm sim ntawm qhov nrawm nrawm thaum nyob rau hauv fibrillations cov contractions yog ceev, tsis xwm yeem, thiab uncoordinated. Qhov no yog qhov sib txawv ntawm AFIB thiab VFIB thiab SVT.
