Lub luag hauj lwm thiab tus nqi ntawm ECG Lead Wires nyob rau hauv Emergency Medicine
Tso lus
Nrog kev txhim kho txuas ntxiv ntawm kev kho mob thev naus laus zis, daim ntawv thov ntawm electrocardiogram hauv cov tshuaj kho mob xwm txheej ceev tau dhau los ua ntau thiab ntau dua. Ntawm lawv, electrocardiogram lead hlau plays lub luag haujlwm tsis tuaj yeem hloov tau raws li tus choj txuas rau cov neeg mob thiab cov khoom siv tshuaj xyuas electrocardiogram.
1. Cov hauv paus ntsiab lus thiab cov ntsiab lus ntawm ECG cov hlau lead
ECG cov hlau lead yog siv los txuas tus neeg mob lub cev mus rau cov xov hlau electrode ntawm cov cuab yeej saib xyuas ECG. Hauv kev xyaum kho mob, peb feem ntau siv 12 coj los tsim ECG nto. Cov hlau lead no tau muab faib ua limb leads thiab hauv siab ua. Cov hlau lead no ntes cov hluav taws xob ua haujlwm ntawm lub plawv los ntawm electrodes thiab hloov mus rau hauv ECG waveforms, uas tuaj yeem soj ntsuam lub plawv los ntawm ntau lub ces kaum thiab pab kws kho mob kuaj mob plawv.
2. Lub luag haujlwm ntawm ECG ua rau cov tshuaj kho mob xwm txheej ceev
2.1 Kev kuaj mob sai ntawm arrhythmia
Hauv kev kho mob xwm txheej ceev, ECG yog ib qho ntawm cov cuab yeej tseem ceeb rau kev kuaj mob plawv xws li arrhythmia. ECG coj, uas yog ib feem tseem ceeb ntawm ECG cov ntaub ntawv, tuaj yeem tau txais tus neeg mob lub ECG cov cim qhia sai thiab pab cov kws kho mob txiav txim siab seb lub plawv dhia puas zoo li qub thiab seb puas muaj teeb meem xws li arrhythmia.
2.2 Saib xyuas lub plawv ua haujlwm
Hauv cov tshuaj kho mob xwm txheej ceev, cov neeg mob yuav tsum tau kuaj xyuas ECG tas li vim muaj lub plawv nres thiab lwm yam laj thawj. ECG cov thawj coj tuaj yeem kuaj pom qhov txawv txav ntawm lub plawv ua haujlwm raws sijhawm los ntawm kev soj ntsuam ECG cov cim tsis tu ncua, muab cov kws kho mob nrog lub hauv paus tseem ceeb hauv kev kuaj mob los qhia txog kev kho mob thiab kev saib xyuas tom ntej.
2.3 Kev kho mob xwm txheej ceev ntawm cov hlab plawv
Thaum muaj xwm txheej ceev, kev kho mob plawv xws li myocardial infarction yuav tsum tau kuaj xyuas sai thiab raug. ECG cov thawj coj tuaj yeem muab cov ntaub ntawv ECG cov ncauj lus kom ntxaws los pab kws kho mob txiav txim siab seb cov neeg mob puas muaj myocardial infarction thiab lwm yam mob raws sijhawm, txhawm rau ntsuas kev kho mob xwm txheej ceev kom txo tau tus neeg mob lub cev tsis zoo thiab kev tuag.
3. Kev siv ECG Leads hauv Kev Kho Mob
3.1 ECG Saib Xyuas
Los ntawm kev siv ECG cov thawj coj, cov neeg ua haujlwm kho mob tuaj yeem saib xyuas cov neeg mob xwm txheej ceev thiab tshawb xyuas qhov mob arrhythmias, myocardial ischemia, thiab lwm yam.
3.2 Kev kuaj ECG
Daim ntawv thov ntawm ECG ua rau cov kws kho mob kom tau txais cov ntaub ntawv zoo - ECG cov ntaub ntawv zoo, uas pab txhawm rau txheeb xyuas cov kab mob plawv thiab siv cov kev kho mob raws sijhawm, yog li txhim kho cov txiaj ntsig kev kho mob thiab kev ciaj sia ntawm cov neeg mob.
3.3 Kev saib xyuas chaw taws teeb
Nrog kev txhim kho txuas ntxiv ntawm kev siv thev naus laus zis kho mob, ECG cov hlau lead hlau kuj tuaj yeem siv rau kev soj ntsuam ECG nyob deb. Cov neeg ua haujlwm kho mob tuaj yeem tau txais cov neeg mob cov cim ECG hauv lub sijhawm tiag tiag los ntawm cov chaw taws teeb saib xyuas, kuaj xyuas cov xwm txheej txawv txav hauv lub sijhawm thiab cuam tshuam, thiab muab kev pabcuam khomob ntau dua thiab sijhawm sijhawm rau cov neeg mob xwm txheej ceev.
Raws li ib feem tseem ceeb ntawm ECG cov ntaub ntawv, ECG cov hlau lead ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv cov tshuaj thaum muaj xwm txheej ceev. Nws tsis tuaj yeem pab cov kws kho mob sai sai kuaj mob arrhythmias thiab saib xyuas lub plawv ua haujlwm, tab sis kuj tseem muab cov ntaub ntawv kuaj mob tseem ceeb hauv cov xwm txheej kub ntxhov los qhia kev kho mob thiab kev saib xyuas. Nrog kev txhim kho txuas ntxiv ntawm kev kho mob thev naus laus zis, nws ntseeg tau tias daim ntawv thov ntawm ECG cov hlau lead hauv cov tshuaj thaum muaj xwm txheej ceev yuav dhau los ua ntau dua, muab kev tiv thaiv zoo dua rau cov neeg mob kev noj qab haus huv thiab kev nyab xeeb ntawm lub neej.
