Cov lus qhia ntawm kev siv:
1. Paub meej tias cov hlau lead yog txuas rau cov ceg ntoo kom raug thiab qhov hluav taws xob ua tau zoo.
2. Thaum ua ECG, yog hais tias qhov ntau ntau tshaj li qhov ntau ntawm ECG daim duab thiab lub plawv dhia qeeb lossis nrawm dhau, kho qhov voltage thiab ntawv ceev rau qhov tsim nyog hauv lub sijhawm.
3. Thaum tus neeg mob ntxhov siab yuav siv tshuaj electrocardiogram, tsev neeg yuav pab ua tus electrocardiogram, thiab siv hom kev los ua taug txhuas-los ntawm taug txhuas cov kauj ruam ntawm kauj ruam.
4. Thaum lub sijhawm kuaj ECG, yog tias muaj kev txawv txav (muaj kev hloov tsis meej) pom hauv ECG tshwj xeeb, koj yuav tsum hu rau tus kws kho mob kom ncav sijhawm thiab txwv tus neeg mob' s kev ua ub no. Tom qab ECG ua tiav, cov ntaub ntawv ntawm tus neeg mob (suav nrog lub npe, hnub nyoog, sijhawm) yuav tsum sau thiab sau cia hauv lub sijhawm.
5. Tom qab nrhiav cov pa hluav taws xob sib xyaw kaum ob, yog tias muaj qoj Q tsis txaus hauv cov hlau lead III (ntawd, Q yoj ntau dua 1 ∕ 4R yoj), ib qho kev tshoov siab yuav tsum tau ntxiv. Yog tias R yoj hauv kev coj ua V1 thiab V2 yog qhov siab, lossis yog pos tom qab lub zog myocardial infarction, yuav tsum muaj V7-V9 ntxiv; yog tias tsam raug ventricular infarction yog xav tias tsam, hmoov txhuas V3-V6R yuav tsum tau ntxiv.
6. Yog tias koj tswj tsis tau qhov xwm txheej ceev, koj yuav tsum hu rau tus kws qhia qib siab kom ncav sijhawm kom muaj kev nyab xeeb txog kev noj qab haus huv.
