Txhawm rau nyeem ECG (electrocardiogram) ntawm tus neeg mob saib xyuas, ua raws li cov kauj ruam no:
Tshawb xyuas tus neeg mob cov ntaub ntawv pej xeem, xws li lawv lub npe, hnub nyoog, thiab poj niam txiv neej, kom ntseeg tau tias nws phim tus neeg mob koj saib xyuas.
Ntsuam xyuas lub hauv paus los yog so lub suab nrov. Nrhiav ib txoj kab ncaj nraim hu ua isoelectric kab, uas qhia tau hais tias lub teeb liab tsis tuaj yeem khaws cov khoom hluav taws xob. Xyuas kom lub monitor txuas tau zoo thiab cov hlau lead tau txuas nrog rau tus neeg mob lub hauv siab.
Saib cov waveforms ntawm ECG tracing. Txheeb xyuas qhov sib txawv ntawm cov waveform:
P yoj: Sawv cev rau atrial depolarization, qhia qhov pib ntawm atrial contraction.
QRS complex: Reflects ventricular depolarization, qhia qhov pib ntawm ventricular contraction.
T yoj: Sawv cev rau ventricular repolarization, qhia txog theem rov qab ntawm lub ventricles.
PR ncua sij hawm: Kev ntsuas los ntawm qhov pib ntawm P yoj mus rau qhov pib ntawm QRS complex, qhia txog lub sij hawm coj mus rau hluav taws xob impulse los ntawm atria mus rau lub ventricles.
QT ntu: Kev ntsuas los ntawm qhov pib ntawm QRS complex mus rau qhov kawg ntawm T yoj, sawv cev rau tag nrho ventricular depolarization thiab lub sij hawm repolarization.
Txheeb xyuas qhov sib dhos los ntawm kev soj ntsuam qhov tsis tu ncua thiab sib xws ntawm cov waveforms. Txheeb xyuas lub plawv dhia los ntawm kev suav cov lej ntawm QRS complexes hauv lub sijhawm tshwj xeeb (piv txwv li, ib feeb). Lub plawv dhia li qub poob ntawm 60-100 neeg ntaus ib feeb.
Txheeb xyuas qhov txawv txav lossis qhov tsis sib xws hauv ECG tracing, xws li arrhythmias, hloov ischemic, kev coj txawv txawv, lossis lwm yam mob plawv. Tham nrog tus kws kho mob lossis tus kws kho mob tshwj xeeb yog tias koj tsis paub meej lossis pom tias muaj qhov sib txawv ntawm qhov qub.
Lub luag haujlwm ntawm ECG (Electrocardiogram) yog ntsuas thiab sau cov haujlwm hluav taws xob ntawm lub plawv. Nws yog ib qho kev kuaj mob uas tsis muaj kev cuam tshuam uas siv los ntsuas lub plawv dhia, tus nqi, thiab kev noj qab haus huv ntawm lub plawv tag nrho.Lub ECG ua haujlwm los ntawm kev kuaj xyuas thiab sau cov cim hluav taws xob uas tsim los ntawm lub plawv thaum nws cog lus thiab so. Cov teeb liab hluav taws xob no tau khaws los ntawm cov hluav taws xob tso rau ntawm daim tawv nqaij thiab tom qab ntawd nthuav dav thiab nthuav tawm raws li daim duab ntawm lub monitor lossis daim ntawv strip.Lub ECG muab cov ntaub ntawv tseem ceeb txog lub plawv hluav taws xob thiab tuaj yeem pab txheeb xyuas ntau yam mob plawv, suav nrog: lub plawv tsis zoo. rhythms (arrhythmias): ECG tuaj yeem kuaj pom lub plawv dhia tsis xwm yeem, xws li atrial fibrillation, ventricular tachycardia, lossis bradycardia.Myocardial infarction (lub plawv nres): Qee qhov kev hloov pauv hauv ECG tus qauv tuaj yeem qhia tias mob plawv lossis ischemia (txo cov ntshav ntws mus rau lub plawv) .Structural abnormalities: ECG abnormalities tuaj yeem muab cov ntsiab lus hais txog cov xwm txheej xws li lub plawv loj, pericarditis, lossis muaj teeb meem ntawm lub plawv valve.Conduction abnormalities: ECG tuaj yeem ntes cov teeb meem hauv lub plawv hluav taws xob, xws li atrioventricular block lossis bundle ceg block.Drug effect los yog electrolyte imbalances: Qee cov tshuaj los yog electrolyte cuam tshuam tuaj yeem ua rau muaj kev hloov pauv hauv ECG qauv.Lub ECG yog ib qho tseem ceeb hauv kev kuaj mob thiab saib xyuas lub plawv thiab feem ntau yog siv rau hauv chaw kho mob, chav kho mob xwm txheej ceev, thiab thaum lub sij hawm kuaj xyuas. Nws pab cov kws kho mob soj ntsuam lub plawv kev ua haujlwm, txiav txim siab txog kev kho mob uas tsim nyog, thiab saib xyuas cov txiaj ntsig ntawm kev kho mob raws sij hawm.
