Nws pab tsim lub posterior sab laug ventricular ceg los yog posterolateral cov leeg.
Dhau li, dab tsi yog cov hlab plawv loj?
Cov Coronary hlab ntsha yog cov hlab ntsha uas muab ntshav rau koj lub plawv. Lawv ceg tawm ntawm aorta ntawm nws lub hauv paus. Txoj cai kab mob plawv , sab laug lub plawv loj , sab laug anterior nqis, thiab sab laug circumflex cov leeg , yog cov plaub cov hlab ntsha loj loj.
Tom qab ntawd, lo lus nug yog, qhov hnyav npaum li cas yog txoj hlab ntshav txhaws? Txoj cai - sab coronary hlab ntsha occlusion tuaj yeem ua rau bradycardia, lub plawv nres, thiab qis dua lossis txoj cai ventricular myocardial infarction (MI).
Raws li, lub luag haujlwm ntawm cov hlab ntsha hauv plawv yog dab tsi?
Coronary cov hlab ntsha muab ntshav rau cov leeg nqaij. Zoo li txhua lwm cov ntaub so ntswg hauv lub cev, cov leeg nqaij hauv lub plawv xav tau cov ntshav muaj oxygen muaj nuj nqi . Tsis tas li ntawd, cov ntshav uas tsis muaj oxygen yuav tsum tau nqa mus. Cov ceg me me dhia rau hauv cov leeg nqaij kom coj nws cov ntshav.
Cov hlab plawv twg feem ntau raug thaiv?
LAD

Dab tsi yog pathology ntawm tus kab mob coronary artery?
Kab mob plawv mob plawv, tseem hu ua kab mob plawv mob plawv lossis kab mob plawv ischemic, kab mob tshwj xeeb los ntawm kev tsis txaus cov pa oxygen txaus rau cov leeg nqaij (myocardium) vim qhov nqaim lossis thaiv ntawm cov hlab ntshav txhaws los ntawm cov rog rog (saib atherosclerosis)
Thawj ceg ntawm txoj cai coronary artery yog dab tsi?
Txoj Cai Coronary Artery (RCA) Hauv 50-60% thawj ceg ntawm RCA yog cov ceg me me, uas muab cov hlab ntsha sab xis. Hauv 20-30% cov ceg conus tshwm sim ncaj qha los ntawm aorta
Yuav ua li cas yog qhov zoo tshaj plaws uas tsis yog invasive kuaj rau tus kab mob coronary artery?
