Systolic thiab diastolic siab yog cov yam ntxwv tseem ceeb ntawm cov hlab plawv thiab cov hlab plawv ntawm tib neeg lub cev. Qhov ntsuas qis - diastolic siab - qhia txog tus nqi ntawm qhov ntsuas no thaum lub sijhawm so (diastole) ntawm lub plawv. Systolic siab sib raug rau lub sijhawm thaum cov ntshav ntws mus rau hauv cov hlab ntsha (systole) thiab yog cov ntshav siab siab.
Hmoov tsis zoo, ntau tus neeg ntawm cov hnub nyoog hluas zuj zus tau nce ntshav siab (tus nqi diastolic). Yog vim li cas rau qhov no yog kev ntxhov siab tsis zoo, kev xav tsis zoo, kev cuam tshuam ntawm lwm yam. Thaum lub sij hawm xws li tshwm sim, qhov ceev ntawm cov ntshav ncig nce thiab, raws li, lub siab ntawm cov hlab ntsha. Nws tus nqi nyob ntawm qhov degree ntawm patency ntawm peripheral hlab ntsha, elasticity ntawm lawv cov phab ntsa thiab zaus ntawm pulsations.
Qhov piv ntawm qhov ntsuas siab thiab qis ntawm cov ntshav siab yog pom zoo - 120/80 mm Hg. Art. Rau txhua tus neeg, vim nws cov yam ntxwv ntawm lub cev, cov duab no yuav txawv me ntsis. Tshaj lawv cov nqi tshaj 140/90 mm Hg. Art. suav tias yog qhov pib ntawm arterial hypertension. Qhov twgnce kev pheej hmoo ntawm cov kab mob xws li myocardial infarction thiab mob stroke. Qhov sib txawv ntawm systolic thiab diastolic siab yog suav tias yog qhov qub ntawm tus nqi ntawm 30-40 units. Qhov txawv no hu ua pulse pressure.
siab diastolic ntshav siab
Kev nce siab ib ntus hauv qee qhov xwm txheej tsis txaus ntshai tshwj xeeb. Yog tias lub siab nce siab (diastolic) thiab tsis txo qis rau lub sijhawm ntev, nws yuav tsum tau kuaj xyuas los ntawm cov kws tshaj lij. Nrog kev ruaj khov nce hauv qhov ntsuas no los ntawm 5 mm Hg. Art. 20% nce kev pheej hmoo ntawm myocardial infarction thiab 30% nce kev pheej hmoo mob stroke.
Kev kub siab tuaj yeem tshwm sim vim muaj kab mob ntawm lub raum, qog adrenal, kab mob endocrine, kab mob plawv, nrog rau kev tsim cov qog hauv lub cev. Nrog rau qhov txo qis hauv cov ntshav khiav, ob lub raum tsim cov tshuaj renin, uas yog cov khoom siv roj ntsha. Lub suab ntawm cov leeg ntawm cov hlab ntsha nce, qhov tshwm sim yog nce siab. Diastolic siab yog li qee zaum hu ua lub raum siab.
Tab sis cov no tsuas yog ua rau muaj qhov txawv txav qis, lwm yam tseem cuam tshuam rau nws qhov taw qhia. Txhawm rau kom paub qhov tseeb ntawm qhov tshwm sim, nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas, suav nrog kev kawm txog qib hormonal, biochemical tsom xam cov zis, ntshav, thiab lwm yam.
Yog qhov ntsuas ntshav siab yog 120/100 lossis 130/115 mm Hg. Art., ces qhov qis dua yog nce (diastolic) nrog ib txwm systolic. Cov ntsuas no hu ua cais diastolic siab. Nwstxaus ntshai heev, vim hais tias lub plawv nyob rau hauv cov ntaub ntawv no nyob rau hauv lub sij hawm nro, uas ua rau impaired ntshav txaus nyob rau hauv nws cov leeg.
Vim li ntawd, cov hlab ntsha poob lawv elasticity, lawv permeability cuam tshuam. Yog hais tias pathological hloov nyob rau hauv lub plawv cov leeg ua irreversible, qhov no ua rau cov ntshav txhaws.
Tom qab txheeb xyuas qhov xwm txheej ntawm tus kab mob, cov kws kho mob tshwj xeeb yuav tsum tau sau cov tshuaj tsim nyog uas tuaj yeem ua ke nrog kev siv tshuaj tiv thaiv kab mob siab thiab tshuaj sedative.
qis diastolic ntshav siab
Thaum lub siab diastolic qis (tsawg dua 60 mmHg), nws tuaj yeem yog ob qho tib si sib txawv thiab cov xwm txheej pathological - hypotension. Qhov no, nyob rau hauv lem, tej zaum yuav tshwm sim los ntawm lwm yam kab mob, kev tsis haum tshuaj los yog endocrine pathology.
Qhov ntsuas ntawm qhov siab qis no pom nyob rau hauv 5% ntawm cov txiv neej thiab cov poj niam ntawm nruab nrab thiab txawm hluas thiab yuav tsis cuam tshuam rau kev noj qab haus huv. Tab sis nrog tus nqi qis tsis tu ncua, koj yuav tsum mus ntsib kws kho mob. Qhov no tuaj yeem tsim kev phom sij tshwj xeeb rau cov poj niam cev xeeb tub.
