Yooj yim PQRST :
Cov Lus Qhia: P- nthwv dej sawv cev ATRIAL DEPOLARIZATION (depolarization yog qhov loj, zoo nkauj lo lus rau CONTRACTION) QRS Complex: Qhov chaw tom ntej koj pom yog qhov loj loj. Qhov ntsuas no hu ua QRS txoj. Cov pob khoom ntawm Nws, cov ceg ntoo, thiab Purkinje fibers yog lub luag haujlwm rau qhov no.
Khaws qhov no hauv kev xav, Pqrst txhais li cas ntawm ECG?
PQRST tej zaum yuav xa mus rau: The PQRST txoj kev, ib txoj kev kawm. OPQRST, mnemonic pib siv los ntawm cov neeg ua haujlwm pabcuam thawj zaug, tshem tawm O rau qhov pib ntawm qhov kev tshwm sim. Ib feem ntawm zaj nkauj Alphabet. Ib lub plawv dhia tiav hauv ECG (P-wave, QRS complex, T-wave)
Ib yam nkaus, vim li cas Pqrst siv rau ntawm ECG yoj? Vim nws siv ABCD los qhia qhov nthwv dej nyob rau hauv lub uncorrected tracing, nws raug yuam kom nrhiav tau lwm cov ntawv los sau nws kho nkhaus, uas nws superimposed rau qhov tsis kho tracing. Nws xaiv PQRST.
Tib neeg tseem nug, P P QRS thiab T ntab sawv cev dab tsi?
Atrial thiab ventricular depolarization thiab repolarization yog sawv cev ntawm ECG raws li ib tug series ntawm nthwv dej : ua P yoj ua raws li cov QRS complex thiab T wave . Thawj deflection yog tus P yoj cuam tshuam nrog txoj cai thiab sab laug atrial depolarization. Qhov thib ob yoj yog QRS nyuaj.
Qhov siab tshaj ntawm ECG txhais li cas?
Ib ECG qhia ntau hom "nthwv dej" ntawm hluav taws xob teeb liab. "P" nthwv dej yog thawj zaug me me ncov hauv ECG . Nws qhia txog hluav taws xob impulse nyob rau sab sauv ntawm koj lub siab. QRS txoj haujlwm nyuaj sau cov haujlwm hluav taws xob hauv chav qis ntawm koj lub siab. "T" nthwv dej yog qhov kawg me me ncov hauv ECG.

ST ntu ntawm ECG sawv cev dab tsi?
ST ntu yog lub tiaj, ntu isoelectric ntawm ECG nruab nrab ntawm qhov kawg ntawm S yoj (J point) thiab pib ntawm T wave. The ST Segment sawv cev rau lub caij nyoog nruab nrab ntawm qhov chaw tso pa tawm thiab rov ua dua tshiab
Dab tsi yog qhov txawv ntawm cov nyhuv ntawm tus neeg sawv cev thiab kev nthuav tawm ntawm lub luag haujlwm?
Kev faib lub luag haujlwm hais txog qhov tseeb tias raws li cov neeg nyob sab nraud nce ntxiv, kev lav phib xaub tus kheej uas ib tus neeg nyob sab nraud xav tias txo qis. Kev faib tawm ntawm lub luag haujlwm raug txo, txawm li cas los xij, thaum tus neeg sawv cev ntseeg tias lwm tus tsis nyob hauv txoj haujlwm los pab
