Thaum lub sij hawm ventricular contraction, lub atria so (atrial diastole) thiab tau txais venous rov los ntawm ob lub cev thiab lub ntsws. Tom qab ntawd, nyob rau hauv ventricular diastole, lub sab hauv sab xis, tso cai rau pib passive filling ntawmcov tuab-walled ventricles thiab khoob ntawm atria.
Puas ventricular filling passive lossis nquag?
Lub sijhawm puv nrawm no yog tshwm sim los ntawm nquag nqus cov ntshav rau hauv lub ventricle thiab yog lub luag haujlwm rau feem ntau ntawm kev txhaws thaum lub sijhawm diastole [17]. Kev txhaws qeeb tshwm sim los ntawm qhov tsis txaus siab ntawm lub plawv los ntawm cov hlab ntsws.
Yuav ua li cas feem pua ntawm ventricular filling yog passive?
Atrial contraction (Thawj Theem)
Qhov no yog theem ntawm atrial contraction. 80% ntawm ventricular filling tau ua dhau los txawm tias ua ntej qhov pib ntawm atrial contraction thiab 20% ntawm cov ventricular filling yog vim atrial contraction. Qhov active filling ntawm ventricles yuav ua rau muaj txiaj ntsig thaum lub cev ua si.
Puas passive lossis active ventricular filling tshwm sim ua ntej?
Atrial contraction ib txwm suav txog li 10% ntawm sab laug ventricular filling thaum tus neeg so vim tias feem ntau ntawm ventricular filling tshwm sim ua ntej atrial contraction raws li cov ntshav ntws los ntawm lub ntsws. cov leeg, mus rau sab laug atrium, ces mus rau sab laug ventricle los ntawm qhib mitral valve.
ventricular filling yog dab tsi?
Definition. Lub siab uas tsim nyob rau hauv lub ventricle lilub ventricle tau puv nrog cov ntshav, feem ntau sib npaug rau qhov nruab nrab atrial siab thaum tsis muaj A-V valvular gradient.
Pom zoo:
Puas glut transporters active lossis passive?
Muaj ob hom kev thauj cov piam thaj hauv lub hlwb: cov piam thaj thauj cov protein (GLUTs) uas thauj cov piam thaj los ntawm kev yooj yim diffusion (a daim ntawv thauj mus los), thiab sodium- dependent glucose transporters (SGLTs) uas siv lub zog-coupled mechanism (active thauj) .
Kuv puas xav tau qhov filling tiag tiag?
Koj yuav xav tau qhov txhaws yog tias koj hnov mob lossis yog lub qhov pom ntawm qhov muag Qee tus neeg nyob hauv pawg pheej hmoo siab dua rau kev kho hniav vim yog caj ces, kev tu hniav tsis zoo los yog kev txhawj xeeb txog kev noj haus.
Puas ventricular rhythms muaj p nthwv dej?
Unifocal PVCs txhua tus muaj ib qho morphology. Ntau qhov sib txawv QRS morphologies yog hu ua "multifocal PVCs" thiab feem ntau yog los ntawm ntau qhov chaw hauv ventricles. Feem ntau, tsis muaj P nthwv dej qhia ua ntej ntxovQRS complex .
Amalgam filling nyob qhov twg?
Thaum muab tshuaj txhuam hniav, tus kws kho hniav thawj zaug tho cov hniav kom tshem tau cov hniav thiab tom qab ntawd cov duab cov hniav kab noj hniavrau kev tso cov khoom sib xyaw. Tom ntej no, nyob rau hauv qhov tsim nyog kev nyab xeeb, tus kws kho hniav sib tov cov hmoov nplej nrog cov kua mercury los ua ib qho amalgam putty .
Puas yog kuv qhov filling ua tsis tiav?
Koj kuj tuaj yeem hnov mob, lossis pom tias koj qhov txhaws tuaj yeem "muab" nyob rau hauv siab. Ob leeg yog cov tsos mob ntawm kev ua tsis tiav amalgam filling. Cov khoom sib xyaw dawb feem ntau pib ua rau mob thaum lawv ua tsis tiav.
