Ventricular Tachycardia vs Ventricular Fibrillation
Arrhythmia txhais tau hais tias lub plawv dhia tsis zoo, thiab qeeb arrhythmias hu ua bradyarrhythmias thiab ceev ceev hu ua tachyarrhythmias. Muaj ntau hom arrhythmias. Lawv yog atrial tachycardia (monofocal lossis multifocal), atrial fibrillation, atrial flutter, atrioventricular nodal re-entry tachycardia, atrioventricular re-entry tachycardia, ventricular tachycardia thiab ventricular fibrillation. Ventricular tachycardia thiab ventricular fibrillation yog ob qho tib si loj arrhythmias. Ob leeg pib nyob rau hauv lub ventricles hauv qab lub atrioventricular node (uas yog lub thib ob natural pacemaker ntawm lub plawv). Myocardial infarction, o ntawm myocardium, cardiomyopathies, electrolyte imbalances thiab lwm yam metabolic abnormalities yuav ua rau ventricular tachycardia thiab fibrillation. Cov tsos mob ntawm ob qho tib si ventricular tachycardia thiab ventricular fibrillation yog palpitations, mob hauv siab, thiab ua pa nyuaj. Lawv yog cov txaus ntshai heev vim hais tias nyob rau hauv qee cov neeg mob uas muaj ventricular tachycardia thiab ventricular fibrillation ob leeg yog tshwm sim ntawm lub plawv nres. Yog li ntawd, nws yog ib qho tseem ceeb kom nkag siab tias ob qho xwm txheej no ua rau muaj kev hem thawj rau lub neej thiab xav tau kev nkag mus rau chav xwm txheej ceev.
Ventricular tachycardia
Ventricular tachycardia yog qhov txawv txav ntawm lub ventricular atherosclerosis nrog lub plawv dhia siab tshaj 100 neeg ntaus ib feeb. Ventricular tachycardia tshwm sim nrog palpitations, mob hauv siab, thiab ua pa nyuaj. Lawv kuj tuaj yeem nyob hauv lub xeev ntawm lub plawv nres. Electrocardiogram (ECG) qhia R tsis tu ncua thaum tsis muaj atrial atherosclerosis. Tag nrho R nthwv dej zoo sib xws thiab tsis tu ncua. Ventricular tachycardia tuaj yeem yog qhov dav lossis nqaim. Feem ntau QRS complex nyob rau hauv ECG uas cim lub ventricular contraction yog peb me me squares ntev. Yog hais tias lub complex yog dav dua peb lub me me square, nws yog hu ua ib tug dav complex ventricular tachycardia thiab, yog hais tias nqaim, nws yog hu ua ib tug nqaim complex ventricular tachycardia. Nws yog ib qho tseem ceeb rau kev sib txawv ntawm ob qho tib si hauv qhov chaw kho mob vim tias cov txheej txheem tswj kev sib txawv heev.
Ventricular tachycardia tuaj yeem ua rau pulseless lossis nrog mem tes. Cov kab mob ventricular tachycardia feem ntau muaj cov mem tes thaum lub broad complex tej zaum yuav los yog tsis. Pulseless ventricular tachycardia yog lub plawv nres thiab cov txheej txheem cardiopulmonary resuscitation tam sim ntawd yuav tsum tau siv los cawm tus neeg mob txoj sia. Rau cov lus piav qhia luv luv ntawm cov txheej txheem cardiopulmonary resuscitation saib hauv qab no hauv ventricular fibrillation.
Nyob rau hauv tag nrho cov tachycardias tus neeg mob yuav tsum tau mus rau hauv chav kho mob xwm txheej ceev, muab tso rau hauv ib lub txaj tiaj tus, IV nkag tau ruaj ntseg, oxygen muab nrog ib tug siab txaus tus nqi, lub plawv saib, thiab ib tug ECG yuav tsum tau noj. Ventricular arrhythmias tau yooj yim pom ntawm ECG. Nyob rau hauv dav tachycardia, tsis muaj mem tes yuav tsum ua rau CPR thaum muaj yuav tsum ua rau kev ntsuam xyuas kom paub seb cov ntshav siab qis dua 90mmHg, lub plawv dhia siab tshaj 150, mob hauv siab yog nyob ntawd, thiab lub plawv tsis ua hauj lwm muaj. Yog tias cov cim kev phom sij no nyob ntawd, tus neeg mob xav tau DC cardioversion tam sim ntawd ua raws li kev kho mob cardioversion. Yog tias tsis muaj kev phom sij, kev kho mob cardioversion tuaj yeem ua ntej. Potassium thiab magnesium qib yuav tsum tau kuaj thiab kho vim tias lawv ob leeg yog arrthymogenic. Nqaim txoj kev ventricular tachycardia xav tau vagal maneuvers, IV adenosine ntxiv rau cardioversion. Tom qab ua kom ruaj khov, cov tshuaj tiv thaiv qhov ncauj yuav tsum pib thiab txuas ntxiv mus.
Ventricular Fibrillation
Hauv ventricular fibrillation, tsis muaj QRS complexes. Tsis muaj mem tes, thiab tus neeg mob nyob hauv plawv nres. IV kab, oxygen siab txaus, thiab lub plawv saib xyuas yuav tsum tam sim ntawd. Tom qab ob lub pa cawm siav, CPR tuaj yeem pib. Yog tias lub plawv saib pom pom ventricular tachycardia lossis ventricular fibrillation (tsuas yog ob qho kev poob siab), defibrillation yuav tsum tau ua ntawm 360j. Qhov no yuav tsum tau ua raws li 1 feeb ntawm CPR. 1mg ntawm adrenaline yuav tsum tau muab IV thaum CPR mus dhia pib lub plawv. Yog tias lub plawv saib pom qee qhov kev sib tw, tsis muaj kev poob siab. Qhov laj thawj rau kev ntes yuav tsum nrhiav. Cov ntshav tsis muaj oxygen, ntshav siab carbon dioxide, cov tub ntxhais kub tsis tshua muaj siab, tsis muaj ntshav siab, ntshav ntim qis, nro pneumothorax, plawv tamponade, co toxins, thiab pulmonary embolism yog qhov tseem ceeb tiv thaiv.
Qhov txawv ntawm Ventricular Tachycardia thiab Ventricular Fibrillation yog dab tsi?
• Ventricular tachycardia muaj QRS complexes hauv ECG thaum fibrillation tsis.
• ventricular tachycardia tej zaum yuav nqaim lossis dav nyuaj thaum fibrillation tsis tuaj yeem faib.
• ventricular fibrillation ib txwm yog ib qho kev raug ntes thaum lub plawv tsis muaj zog tachycardia yog qhov raug ntes.
