ECG saib, koj puas tau paub cov hauv paus?
Lub hauv paus ntsiab lus
Los ntawm kev txheeb xyuas qhov sib txawv (piv txwv li txhuas) ntawm ob lub ntsiab lus tshwj xeeb ntawm lub cev saum npoo ntawm lub plawv hluav taws xob ua haujlwm los cuam tshuam txog kev ua haujlwm ntawm lub plawv.
Yim lub cim tseem ceeb ntxiv: qhia txog tus neeg mob qhov xwm txheej tseem ceeb ntawm yim lub cim. Cov no muaj xws li lub cev kub, mem tes, ua pa, ntshav siab, lub hlwb, cov menyuam kawm ntawv, tso zis tso zis, thiab daim tawv nqaij mucosa.
ECG thiab electrocardiogram
ECG - Lub plawv dhia thiab diastole ntawm lub plawv yog lub zog ntawm cov ntshav ncig hauv cov hlab ntsha. Lub excitation thiab excitation propagation ntawm cardiac leeg hlwb yog raws li lub bioelectric kev ua ntawm lub cell membrane. Tag nrho ntawm tag nrho cov myocardial cell membrane bioelectrical kev ua ub no yog lub teeb liab electrocardiographic.
ECG - ECG teeb liab taug kev los ntawm cov ntaub so ntswg ntawm lub cev mus rau lub cev, qhov chaw uas nws tau saib xyuas siv ECG electrodes thiab taug qab ntawm lub sijhawm axis los tsim ECG.
Cov kws saib xyuas feem ntau muaj peev xwm saib xyuas ntau lossis kaum ob-tus thawj coj ECGs thiab tuaj yeem soj ntsuam ntxiv ntawm ECG waveforms, xws li arrhythmia analysis, pacing analysis, thiab ST-segment analysis.
Kev soj ntsuam ECG tsis yog qhov hloov pauv tag nrho rau lub tshuab ECG tus qauv. Tam sim no saib ECG waveforms feem ntau tseem tsis tau muab cov qauv zoo dua ntawm ECG waveform, thiab ob lub twj paj nruag muaj qhov sib txawv bandwidths hauv kev ntsuas Circuit Court.
Leej twg siv
Txhua tus neeg mob uas nws tus mob tseem ceeb heev thiab yuav tsum tau saib xyuas tas li thiab tsis cuam tshuam txog kev ua haujlwm ntawm ECG (ntau zaus thiab atherosclerosis ntawm lub plawv dhia, lub plawv dhia), lub cev kub, ua pa, ntshav siab (tsis muaj kev cuam tshuam lossis cuam tshuam), ib nrab siab ntawm qhov kawg ntawm cov pa roj carbon dioxide, Central venous siab thiab transcutaneous oxygen saturation.
Electrodes thiab qhov chaw ntawm txhua lub electrode
Muaj tsib electrodes tso rau hauv qab no
Sab xis sab xis (RA): Thawj qhov chaw intercostal ntawm kab midclavicular ntawm sab xis ntawm lub sternum.
Txoj cai qis (RL): txoj cai midclavicular kab ntawm theem ntawm fenestra.
Nruab nrab (C): plaub qhov chaw intercostal ntawm sab laug ntawm lub sternum.
Sab laug sab laug (LA): thawj qhov chaw intercostal nyob rau hauv midclavicular kab ntawm sab laug ntug ntawm lub sternum
Sab laug qis (LL): nyob rau theem ntawm fenestra ntawm sab laug midclavicular kab
Qhov chaw ntawm peb lub taub hau
Dawb (sab caj npab) electrode muab tso rau hauv qab clavicle, tawm tsam sab xis ntawm lub xub pwg
Dub (sab laug npab) electrode muab tso rau hauv qab clavicle, tiv thaiv sab laug xub pwg
Liab (sab laug plab) electrode yog muab tso rau hauv sab laug sab plab plab, nyob rau hauv qis ntug ntawm lub costal koov
Lub phaj electrode yuav tsum tau muab tso rau hauv ib txoj kev uas yuav ua tau raws li hauv qab no
1, P nthwv dej yog qhov tseeb thiab pom tseeb (xws li qhov ntswg qhov ntswg).
2, QRS yoj amplitude yuav tsum tau meej thiab ncav cuag ib qho amplitude los ua rau lub plawv dhia thiab lub tswb.
3, Tsis txhob cuam tshuam nrog kev ua haujlwm resuscitation (xws li hluav taws xob defibrillation, thiab lwm yam)
Lub ntsiab kev soj ntsuam ntsuas
1, Saib xyuas thiab sau lub plawv dhia thiab lub plawv dhia tsis tu ncua.
2, Saib seb puas muaj P nthwv dej thiab yuav ua li cas morphology, qhov siab thiab dav ntawm p nthwv dej.
3, Ntsuas p ib lub sijhawm R (0.12-0.21), QT lub sijhawm (0.44-0.36s ntawm lub plawv dhia li qub ntawm 60-100bpm , feem ntau tsawg dua 0.44s hauv cov txiv neej thiab tsawg dua 0.45s hauv cov poj niam thiab menyuam yaus).
4. Saib xyuas seb QRS waveform puas zoo li qub thiab seb puas muaj "tsis raug ntaus".
5, Saib seb qhov T yoj yog qhov qub.
6. Ua tib zoo saib xyuas qhov muaj qhov txawv txav tsis zoo
