Yuav siv ECG tshuab li cas

Vim nws cov cuab yeej kuaj mob paub tab, kev ntseeg tau, kev ua haujlwm yooj yim, tus nqi nruab nrab, thiab tsis muaj kev phom sij rau cov neeg mob, lub tshuab electrocardiogram tau dhau los ua ib qho ntawm cov cuab yeej kuaj mob hauv txaj.Raws li kev nthuav dav ntawm daim ntawv thov txuas ntxiv mus, nws tau dhau los ua ib qho ntawm tsib qhov kev kuaj mob niaj hnub ntawm "ntshav, zis, quav, duab, thiab electrocardiogram", tshwj xeeb tshaj yog rau qee yam kab mob plawv xws li: mob plawv ischemic, mob plawv, mob plawv, myocarditis. , pericarditis, pulmonary embolism thiab arrhythmia muaj tus nqi kuaj mob.Koj puas paub siv nws li cas.

Txhawm rau siv lub tshuab ECG (Electrocardiogram), ua raws li cov kauj ruam no:

1. Npaj tus neeg mob: xyuas kom tus neeg mob nyob hauv qhov chaw xis nyob thiab tau nthuav tawm lawv lub hauv siab.Tej zaum lawv yuav xav tau tshem tawm cov khaub ncaws lossis cov hniav nyiaj hniav kub uas tuaj yeem cuam tshuam nrog kev tso electrode.

2. Fais fab ntawm lub tshuab: Qhib lub tshuab ECG thiab tso cai rau nws ua tiav nws cov txheej txheem pib.Xyuas kom lub tshuab ua haujlwm zoo thiab cov khoom siv tsim nyog, xws li ECG electrodes thiab conductive gel, muaj.

3.Txuas cov electrodes: Muab ECG electrodes rau qhov chaw tshwj xeeb ntawm tus neeg mob lub cev raws li kev qhia los ntawm lub tshuab tsim khoom lossis kws kho mob.Feem ntau, electrodes muab tso rau ntawm lub hauv siab, caj npab, thiab txhais ceg.Ua raws li cov xim-coding ntawm cov electrodes los xyuas kom meej qhov chaw tso.Nov yog qee qhov kev coj ECG: lub hauv siab ua, cov ceg tawv, thiab cov qauv coj.

1) Limb lead kev sib txuas txoj kev: Txoj cai sab sauv - kab liab, sab laug sab sauv - kab daj, sab laug sab ceg - ntsuab kab, txoj cai qis qis - kab dub

2) Txoj kev sib txuas hauv siab:

V1, 4th intercostal qhov chaw ntawm txoj cai ciam teb ntawm sternum.

V2, plaub qhov chaw intercostal ntawm sab laug ciam teb ntawm lub sternum.

Qhov nruab nrab ntawm txoj kab txuas V3, V2 thiab V4.

V4, kev sib tshuam ntawm sab laug midclavicular kab thiab thib tsib intercostal qhov chaw.

V5, sab laug anterior axillary kab yog nyob rau tib theem li V4.

V6, sab laug midaxillary kab yog nyob rau tib theem li V4.

V7, sab laug posterior axillary kab yog nyob rau tib theem li V4.

V8, sab laug scapular kab yog nyob rau tib theem li V4.

V9, sab laug paraspinal kab yog nyob rau tib theem li V4.

(V1-V6 xaim nyob rau hauv kev txiav txim ntawm xim: liab, daj, ntsuab, xim av, dub, liab doog)

4. Npaj daim tawv nqaij: Yog tias tsim nyog, ntxuav tus neeg mob daim tawv nqaij nrog ib qho cawv cawv lossis tshuaj ntxuav zoo sib xws kom tshem tawm cov roj, av, lossis hws.Qhov no pab txhim kho qhov zoo ntawm ECG teeb liab.

5. Siv cov khoom siv hluav taws xob (yog tias xav tau): Qee cov electrodes yuav tsum tau siv cov khoom siv hluav taws xob los txhim kho hluav taws xob tiv tauj nrog daim tawv nqaij.Ua raws li cov lus qhia uas tau muab nrog cov electrodes los yog sab laj nrog lub tshuab cov neeg siv phau ntawv rau daim ntawv thov gel.

6. Txuas cov electrodes rau lub tshuab: Txuas cov electrode coj mus rau cov chaw nres nkoj sib thooj ntawm lub tshuab ECG.Xyuas kom muaj kev sib txuas ruaj ntseg kom tsis txhob muaj cov khoom qub lossis cuam tshuam thaum kaw.

7. Pib cov ntaubntawv povthawj siv: Thaum cov electrodes txuas kom zoo, pib lub kaw lus muaj nuj nqi ntawm lub tshuab ECG.Ua raws li cov lus qhia lossis cov lus qhia muab los ntawm lub tshuab interface.

8. Saib xyuas cov ntaubntawv povthawj siv: Khaws ib lub qhov muag ntawm ECG waveform pom ntawm lub tshuab lub vijtsam.Xyuas kom meej tias cov teeb liab zoo yog qhov zoo, nrog cov qauv meej thiab sib txawv.Yog tias tsim nyog, kho qhov chaw ntawm electrode los yog tshawb xyuas cov kev sib txuas xoob.

9. Xaus cov ntaubntawv povthawj siv: Thaum lub sijhawm kaw qhov xav tau tau ua tiav lossis raws li tus kws kho mob qhia, nres lub kaw lus ntawm lub tshuab.

10. Txheeb xyuas thiab txhais cov ECG: Cov ECG kaw yuav raug tso tawm kom pom raws li daim duab lossis waveform ntawm lub tshuab lub vijtsam.Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev txhais ECG yuav tsum muaj kev paub txog kev kho mob.Tham nrog tus kws kho mob uas tau kawm, xws li kws kho mob lossis kws kho plawv, txhawm rau txheeb xyuas ECG thiab txhais cov txiaj ntsig tau raug.
