Ⅲ. Cov hauv paus

Ib qho electrocardiogram (ECG) yog ib daim duab (kov) uas sau los ntawm lub cev ntawm cov kev hloov hauv hluav taws xob muaj peev xwm tsim los ntawm lub plawv thaum txhua lub voj voog.

Electrocardiogram tuaj yeem cuam tshuam txog bioelectric tej zaum hloov pauv thaum lub sijhawm tiam, kev ua haujlwm thiab rov ua haujlwm ntawm lub plawv excitation.

Cov kws kho mob kuaj xyuas thiab txiav txim siab txog kev ua haujlwm ntawm lub plawv thiab ntau yam kab mob plawv los ntawm kev hloov pauv bioelectrical ntawm lub plawv.

Tus txheej txheem thoob ntiaj teb tam sim no ECG yog tus qauv coj, uas yog tsim los ntawm kaum ob txoj hauv kev, thiab yog li ntawd ECG dav dav yuav qhia kaum ob kab yoj. Los ntawm kev nrhiav tau ntawm cov teeb liab los ntawm kaum ob-lead ECG, nws muaj peev xwm los txiav txim qhov chaw ntawm lub hauv paus chiv keeb thiab txawv txav ntawm lub plawv lesion. Piv txwv li, cov kab mob feem ntau yog myocardial infarction thiab myocardial ischemia. (Ceeb toom: ECG lead yog hais txog qhov chaw ntawm electrodes ntawm tib neeg lub cev nto thiab kev sib txuas ntawm electrodes rau lub amplifier thaum taug qab ECG; txhuas yog ib hom kev sib txuas! Ib qho electrode yog ib qho nruab nrab conductive. ECG electrodes tau muab faib ua limb electrodes (4) thiab hauv siab.

 

● 12-lead yog dab tsi?

12 tus thawj coj suav nrog 6 lub hauv siab coj (I, II, III, aVR, aVL, thiab aVF) thiab 6 lub hauv siab coj (V1 txog V6). Cov ceg ntoo muaj xws li cov txheej txheem bipolar leads (I, II, thiab III) thiab cov hlau lead (aVR, aVL, thiab aVF). Bipolar leads muaj npe rau cov ntaub ntawv ntawm qhov sib txawv voltage ntawm ob theem

● Kev kho mob tseem ceeb thiab daim ntawv thov

- Clinical tseem ceeb: sau cov hluav taws xob ua haujlwm ntawm tib neeg lub siab; pab kuaj mob arrhythmia, myocardial ischemia, myocardial infarction, myocarditis, cardiomyopathy, tsis txaus ntshav hlab ntsha, pericarditis, thiab lwm yam.; pab txiav txim seb cov nyhuv ntawm cov tshuaj los yog electrolyte mob ntawm lub plawv; pab txiav txim seb qhov xwm txheej ntawm artificial heart pacing.

- Siv dav: niaj hnub kuaj lub cev, phais, tshuaj loog, tshuaj saib xyuas, kev ua kis las, aerospace thiab lwm yam kev saib xyuas mob plawv thiab cawm cov neeg mob hnyav.

● Dab tsi yog cov hlau lead thiab channel ntawm lub tshuab ECG?

Lub tshuab ECG nrog kaum ob lub taub hau: lub tshuab tshwj xeeb ECG nrog tag nrho ntawm 12 tus qauv coj hauv lub cev, muaj 3 lub taub hau bipolar, 3 lub taub hau unipolar pressurized limb, thiab 6 lub hauv siab ua. Tag nrho yog 12 tus thawj coj.

Yog li ntawd, kaum ob tus thawj coj tsis yog qhov zoo ntawm lub tshuab EKG tshwj xeeb, tab sis qhov tseem ceeb tshaj plaws!

Yog li dab tsi yog lub tswv yim ntawm kaum ob channel hauv lub tshuab ECG?

12-lead, raws li tau hais ua ntej, tshwm sim nws tus kheej nyob rau hauv daim ntawv ntawm 12-channel waveform, thiab tom qab ntawd peb yuav tsum luam tawm cov ntaub ntawv waveform kaw, thaum lub sijhawm ntawd, ob peb yam tseem ceeb: waveform raug, clarity, thiab ceev ntawm luam tawm.

Yog tias cov ntaub ntawv kaw lus loj, qhov kev teeb tsa txaus, ces 12 cov ntaub ntawv tuaj yeem luam tawm tib lub sijhawm, nyob rau lub sijhawm no, yuav nrawm dua li ib qho channel, peb channel, rau 6 channel, ncaj qha 2 mus rau 12 zaug.

Ntawd yog, ib qho channel tsuas yog ib lub tshuab luam ntawv xwb, peb txoj kab yog luam tawm peb lub waveforms, zoo ib yam, rau txoj kab yuav luam rau rau waveforms, kaum ob-channel tshuab yog luam tawm kaum ob waveforms.
Tib daim tshev, ib leeg-channel tshuab luam tawm 12 zaug luam tawm tag nrho 12-channel waveform, thaum lub tshuab 12-channel yuav ib zaug tag nrho 12-channel waveform luam tawm.

Txoj kev yooj yim tshaj plaws thiab ncaj tshaj plaws los saib qhov no yog saib ntawm qhov chaw ntawm lub tshuab luam ntawv; txawv cardiometers nrog cov lej sib txawv ntawm txoj kab sib txawv muaj qhov dav ntawm cov ntawv luam tawm.
