Lub electrocardiogram saib yog ib qho tseem ceeb rau kev kho mob tam sim no.Txawm hais tias nws yog chav saib xyuas mob hnyav lossis ib pawg neeg saib xyuas dav dav, nws feem ntau nruab nrog cov khoom siv zoo li no.
Lub hom phiaj tseem ceeb ntawm ECG saib yog txhawm rau kuaj thiab tso saib ECG teeb liab tsim los ntawm tus neeg mob lub plawv mem tes.Cov kab hluav taws xob sab hauv ntawm lub tshuab ntsuas ECG tsis tshua muaj kev puas tsuaj.Feem ntau ntawm cov teeb meem yog ECG lead xov hlau, ECG electrodes thiab teeb tsa.
1. Qhov teeb meem ntawm ECG saib:Feem ntau, cov hlau lead ntawm ECG saib muaj 3 coj thiab 5 coj.Yog tias qhov teeb tsa tsis raug, lub waveform tsis tuaj yeem tshwm sim lossis lub waveform tsis raug.Yog li ntawd, thaum lub ECG saib tsis muaj ECG teeb liab lossis lub waveform tsis raug, ua ntej xyuas seb qhov chaw ntawm lub tshuab puas yog.Tsis tas li ntawd, feem ntau cov saib muaj cov kev lim dej digital uas tuaj yeem lim fais fab zaus cuam tshuam.Feem ntau ECG saib muaj ob lub lim dej ntau zaus, 50 thiab 60HZ, kom lub tshuab tuaj yeem siv tau rau ntau thaj tsam.
2. ECG txhuas hlau tawg:Txoj hauv kev ncaj qha tshaj plaws los ntsuas seb ECG cov hlau lead puas tawg yog siv multimeter.Feem ntau ECG saib tsis tuaj yeem tso saib ECG waveform ntev npaum li ib lub plawv ntawm cov xov hlau tawg.Lub cuab yeej tuaj yeem nias lub electrode kawg ntawm ECG ua rau tus ntiv tes.Yog hais tias lub monitor tuaj yeem tso cov suab nrov nrov, ces ECG txhuas txuas nrog.Yog tias tsis pom lub teeb liab ECG, ECG lead yog tej zaum tawg.
3.Qhov teeb meem ntawm ECG electrode daim ntawv:Qhov zoo ntawm ECG electrode tsis zoo, thiab txoj haujlwm tsis raug yuav ua rau lub tshuab electrocardiograph tsis ntsuas ECG teeb liab lossis ntsuas lub teeb liab tsis raug.Yog tias tsis muaj teeb meem nrog kev saib xyuas thiab ECG cov hlau lead, nws yog ECG electrode teeb meem.Ntau tus kws saib xyuas neeg mob niaj hnub no muaj kev txawj ntse, thiab feem ntau lawv tsis tuaj yeem lo txawm tias ECG electrode.Txoj kev zoo ntawm kev thov ECG electrodes yog siv cov ntawv xuab zeb me me ntawm ECG electrodes los maj mam rub lub stratum corneum ntawm tus neeg mob daim tawv nqaij.Ib me ntsis ntsev.(Ntshuam ECG electrodes feem ntau tsis muaj cov ntawv xuab zeb, thiab lawv tuaj yeem txuas ncaj qha rau tus neeg mob daim tawv nqaij kom tau txais ib qho zoo yoj, tab sis tus nqi kuj yog siab heev. Qhov zoo ntawm domestic ECG electrodes yuav tsis zoo, yog li tau txais ib daim ntawm sandpaper los tiv thaiv nws) Tsis tas li ntawd, qhov kev sib txuas hauv av tsis zoo ntawm cov saib yuav ua rau muaj kev cuam tshuam ntau heev, yog li yuav tsum siv lub ntsuas hluav taws xob thoob ntiaj teb los xyuas qhov voltage ntawm cov xaim hauv av kom ntseeg tau tias cov xaim hauv av zoo li qub.
