atrial depolarization
Ua li no, P wave sawv cev li cas?
Cov P yoj sawv cev depolarization ntawm sab laug thiab sab xis atrium thiab kuj sib xws rau atrial contraction. Hais lus nruj me ntsis, atria daim ntawv cog lus sib faib thib ob tom qab P yoj pib. Vim tias nws me me, atrial repolarization feem ntau tsis pom ntawm ECG.
Ib yam nkaus, P QRS thiab T nthwv dej 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 thib ob, qhov txawv txav P wave txhais li cas?
Ib txawv txav P wave tej zaum qhia atrial o. Atrial depolarization ua raws li qhov tso tawm ntawm qhov sinus node. Feem ntau depolarization tshwm sim ua ntej ntawm sab xis atrium thiab tom qab ntawd hauv sab laug atrium.
P wave deflection sawv cev dab tsi?
Definition/Introduction Lub P yoj thiab PR ntu yog Ib feem tseem ceeb ntawm electrocardiogram (ECG). Nws sawv cev hluav taws xob depolarization ntawm atria ntawm lub plawv. Nws yog feem ntau yog qhov zoo me me deflection los ntawm isoelectric lub hauv paus uas tshwm sim ua ntej lub QRS nyuaj.

Qhov twg yog qhov zoo tshaj plaws hauv qab no piav qhia tias P wave sawv cev li cas?
P yoj ntawm ECG sawv cev rau atrial depolarization, uas ua rau atrial contraction, lossis atrial systole
Nws txhais li cas yog tias ntshav siab sib txawv hauv txhua txhais caj npab?
Lawv kuj muaj kev pheej hmoo ntau ntxiv ntawm kev txhim kho kab mob plawv thiab cuam tshuam txog teeb meem nyob rau 13 xyoos tom ntej. Qhov sib txawv loj hauv kev ntsuas ntshav siab ntawm koj txhais caj npab tuaj yeem yog ib qho cim ntawm teeb meem kev noj qab haus huv, xws li: Cov hlab ntshav txhaws hauv koj txhais caj npab (kab mob hlab ntsha hauv nruab nrog cev) Kab mob hauv lub raum
Npau suav txog plaub txhais taw txhais li cas?
Lub ntsiab lus & piav qhia rau Hairy Feet phau ntawv txhais lus! Yog tias muaj dab tsi tshwm sim rau ib txhais taw hauv kev npau suav, nws yuav cuam tshuam txog nws cov nyiaj txiag sawv, ua haujlwm, ua haujlwm hnyav, nws tus thawj coj lossis nws cov neeg sawv cev.
