Coj hais txog ib txoj kab kev xav ntawm ob ECG electrodes. Cov haujlwm hluav taws xob ntawm qhov no coj yog ntsuas thiab kaw ua ib feem ntawm ECG . A 12 - coj ECG cov ntaub ntawv 12 ntawm cov no " coj "Tsim tawm 12 cais graphs ntawm ECG ntawv. Txawm li cas los xij koj tsuas yog muab 10 lub cev electrodes rau tus neeg mob.
Hauv qhov no, thaj chaw ntawm lub plawv twg ua 12 lead ECG nyeem?
Txoj hauj lwm ntawm rau lub hauv siab electrodes rau tus qauv 12 duav electrocardiography. V1: sab xis sternal ntug, 4th intercostal chaw; V2: sab laug sternal ntug, 4th intercostal chaw; V3: nruab nrab V2 thiab V4; V4: kab nruab nrab-clavicular, qhov chaw thib 5; V5: axillary pem hauv ntej
Tsis tas li ntawd, koj tso tus 12 lead nyob qhov twg? Cov ntawv sau ntxiv rau 12 - coj ECG Placement: Limb coj kuj tuaj yeem tso rau ntawm caj npab thiab ncej qab. Txawm li cas los xij, yuav tsum muaj qhov tsis sib xws hauv koj qhov kev tso kawm. Piv txwv li, tsis txhob xaim hluav taws xob ntawm lub dab teg sab xis thiab ib qho ntawm sab caj npab sab laug. Rau cov poj niam mob, qhov chaw coj V3-V6 hauv qab lub mis sab laug.
Ib yam li ntawd, tus thawj coj twg koj saib ECG?
Xav txog txhua tus coj raws li qhov sib txawv ntawm lub plawv koj yog sim los txhais lus Nyob ntawd yog six limb ( Kuv , II, III, AVR, AVL, AVF) coj thiab rau precordial (V1-V6) coj.
Ua thiab Lub Plawv Pom.
| Coj | Saib |
|---|---|
| Lateral | I, AVL, V5, V6 |
| Sab hauv | V2, V3, V4 |
| Txoj cai atrium thiab kab noj hniav ntawm sab laug ventricle | V1 thiab AVR |
Qhov txiaj ntsig ECG ib txwm yog dab tsi?
Li qub mus txog 120 ms (3 me me squares rau ECG ntawv). QT ncua sij hawm (ntsuas los ntawm thawj deflection ntawm QRS complex mus rau qhov kawg ntawm T yoj ntawm isoelectric kab). Ntau yam mus txog 440 ms (txawm tias nws txawv nrog lub plawv dhia thiab tej zaum yuav ntev me ntsis hauv poj niam)

Koj nyeem qhov siab tshaj plaws li cas?
Tuav lub ncov siab tshaj plaws kom nws yog kab rov tav thiab xyuas kom tseeb tias koj cov ntiv tes tsis cuam tshuam qhov ntsuas ntsuas. ua pa tob tob li koj ua tau thiab tso koj daim di ncauj nruj ib ncig ntawm lub qhov ncauj. ua pa tawm sai thiab nyuaj npaum li koj tuaj yeem ua tau. thaum koj ua tsis taus pa tas li, sau koj cov ntawv nyeem
Koj tso qhov 12 lead ECG nyob qhov twg?
12-Lead ECG Placement V1 (C1) Thib plaub intercostal qhov chaw ntawm txoj cai sternal ciam teb V2 (C2) Thib plaub intercostal qhov chaw ntawm sab laug sternal ciam teb V3 (C3) Ib nrab ntawm cov coj V2 thiab V4 V4 (C4) Thib thib intercostal qhov chaw hauv kab nruab nrab V5 (C5) Sab laug anterior axillary kab ntawm tib lub dav hlau dav li V4
Vim li cas nws thiaj hu ua 12 lead ECG thaum muaj tsuas yog 10 lead?
12-lead ECG qhia, raws li lub npe cuam tshuam, 12 coj uas tau muab los ntawm txhais tau tias ntawm 10 electrodes. Peb ntawm cov coj no yooj yim to taub, vim lawv tsuas yog qhov tshwm sim ntawm kev sib piv cov peev xwm hluav taws xob kaw los ntawm ob lub electrodes; ib qho hluav taws xob tab tom tshawb nrhiav, thaum lwm qhov yog siv hluav taws xob siv
Koj puas tuaj yeem nyeem yam tsis hais cov lus hauv koj lub taub hau?
Yog tias koj tau hnov koj tus kheej hauv koj lub taub hau nyeem ntawv, qhov no yog vim qhov no yog li cas neeg feem coob tau nyeem los nyeem; hais cov lus ntsiag to hauv lawv lub taub hau. Tus cwj pwm no hu ua subvocalization, thiab txawm hais tias feem ntau, nws yog ib qho laj thawj tseem ceeb vim li cas tib neeg nyeem qeeb thiab muaj teeb meem txhim kho lawv cov ntawv nyeem
