P-R Interval Thawj qhov kev ntsuas yog hu ua "P-R ntu" thiab ntsuas los ntawm qhov pib ntawm qhov nce siab ntawm P nthwv dej mus rau qhov pib ntawm QRS nthwv dej QRS nthwv dej Nws feem ntau yog qhov nruab nrab thiab pom tseeb tshaj plaws ib feem ntawm tracing. Nws sib haum mus rau depolarization ntawm sab xis thiab sab laug ventricles ntawm lub plawv thiab contraction ntawm cov nqaij ntshiv loj. Hauv cov neeg laus, QRS complex feem ntau kav 80 mus rau 100 ms; Hauv cov menyuam yaus nws yuav luv dua. https://en.wikipedia.org › wiki › QRS_complex

. Qhov kev ntsuas no yuav tsum yog 0.12-0.20 vib nas this, lossis 3-5 me me squares hauv lub sijhawm.
Lub sijhawm PR ib txwm nyob ntawm ECG yog dab tsi?
Lub sijhawm PR ib txwm yog 0.12 txog 0.20 vib nas this, lossis 120 txog 200 milliseconds. Ntau qhov txawv txav ntawm PR ncua sij hawm - suav nrog kev ncua ntev ntawm PR lub sijhawm, luv luv ntawm PR lub sijhawm thiab kev hloov pauv ntawm kev sib tw mus rau yeej - tuaj yeem tshwm sim; Cov no tau tham ntau yam hauv ECG Kev Tshawb Fawb thiab Cov Cai.
Lub sijhawm PR yog dab tsi?
Lub sijhawm PR sawv cev lub sijhawm ntawm atrial depolarization thiab ventricular depolarization. Qhov txawv txav ntawm lub sij hawm ntawm PR ntu tuaj yeem qhia txog kab mob. Ib lub sijhawm PR ntawm qis dua 120 milliseconds (ms) yuav qhia tau tias cov hluav taws xob impulses mus ntawm atria thiab ventricles sai heev.
Lub sijhawm PR ncua sij hawm yog dab tsi?
Ib lub sijhawm PRLub sijhawm nruab nrab yogncua sijhawm rau lub sijhawm nws siv rau lub teeb liab txav mus hla lub atria saum lub plawv, uas tau txais cov ntshav ntws los ntawm cov leeg, mus rau hauv lub ventricles hauv qab ntawm lub plawv, uas tso cov ntshav tawm mus rau hauv cov hlab ntsha.
Lub sijhawm PR txhais li cas ntawm ECG?
PR ncua sij hawm ntsuas los ntawm qhov chaw electrocardiogram (ECG) txhais tau tias lub sijhawm los ntawm qhov pib ntawm atrial depolarization mus rau qhov pib ntawm ventricular depolarization. Electrocardiographically, ncua sij hawm PR, lossis thawj-degree atrioventricular (AV) thaiv, yog txhais los ntawm PR lub sijhawm >200 ms.
