Muaj feem xyuam nrog kev kaw ntawm mitral thiab tricuspid li qub. Loudest ntawm lub apex.
1. Auscultate lub plawv ntawm ntau qhov chaw.
| S1 | S2 |
|---|---|
| Tsuas yog ua ntej carotid pulse | Ua raws li cov carotid pulse |
| Louder ntawm apex | Nruam ntawm lub hauv paus |
| Tsawg suab thiab ntev dua S.2 | Siab dua thiab luv dua S2 |
| Vim tias systole luv dua diastole: | |
Ib yam nkaus, tib neeg nug, koj tuaj yeem qhia qhov sib txawv ntawm s1 thiab s2 li cas?
Thaum mloog tus neeg mob lub siab, lub plawv dhia ntawm kev ntaus yeej yuav nquag paub qhov txawv S1 los ntawm S2 . Vim tias diastole siv sijhawm li ob zaug ntev li systole, muaj kev ncua ntev dua nruab nrab ntawm S2 thiab S1 dua muaj nruab nrab ntawm S1 thiab S2.
puas yog s1 lossis s2 nrov ntawm aortic? Hauv lub siab qub S1 yog nrov dua tshaj S2 hauv apex, thiab S2 yog nrov dua tshaj S1 hauv paus. S1 yog tsim los ntawm kev kaw ntawm mitral thiab tricuspid li qub thiab lawv nyob ze rau apex ntawm lub plawv. S2 yog tsim los ntawm kev kaw ntawm aortic thiab pulmonary li qub thiab lawv nyob ze rau lub hauv paus ntawm lub plawv.
Kuj paub, koj hnov qhov twg s1 thiab s2 zoo tshaj?
S1 tuaj yeem yog hnov zoo tshaj hla lub apex, siv lub tswb nrov lub tswb lossis diaphragm. Thawj lub siab lub suab yog tshwm sim los ntawm turbulence tsim thaum lub mitral thiab tricuspid qhov tseem ceeb kaw. S1 thiab S2 lub plawv suab feem ntau piav raws li lub - dub.
4 lub siab lub ntsws yog dab tsi?
Plaub Lub Plawv Suab (S4) Plaub lub plawv suab , tseem hu ua "atrial gallop," tshwm sim ua ntej S1 thaum lub atria cog lus yuam cov ntshav mus rau LV. Yog tias LV tsis ua raws, thiab atrial contraction yuam cov ntshav los ntawm atrioventricular li qub, S4 yog tsim los ntawm cov ntshav tawm tsam LV.
