ST-segment elevation myocardial infarction (STEMI) yog qhov mob tshwm sim tshaj plaws ntawm cov kab mob plawvthiab cuam tshuam nrog kev mob hnyav thiab kev tuag. Kev ua tiav thrombotic occlusion tsim los ntawm atherosclerotic plaque nyob rau hauv lub epicardial coronary hlab ntsha yog ua rau STEMI nyob rau hauv feem ntau ntawm cov mob.
Vim li cas St siab hauv myocardial infarction?
ST ntu qhov siab tshwm sim vim thaum lub ventricle nyob ntawm so thiab yog li repolarized, thaj tsam depolarized ischemic generates hluav taws xob tam sim no mus deb ntawm cov kaw lus electrode; Yog li ntawd, lub hauv paus voltage ua ntej QRS complex yog kev nyuaj siab (liab kab ua ntej R yoj).
Puas ST nce siab puas siab puas ntsws?
Ib ntu ST-segment nce siab myocardial infarction (STEMI) yog ib hom mob plawv mob hnyav uas cov hlab ntsha coronary tau thaiv tag nrho thiab ib feem loj ntawm cov leeg plawv tsis tuaj yeem kom tau txais ntshav. "ST ntu elevation" yog hais txog tus qauv uas tshwm sim ntawm electrocardiogram (EKG).
Dab tsi yog myocardial infarction yam tsis muaj ST nce?
Non-ST-elevation myocardial infarction (NSTEMI) yog hom ["lub plawv nres": txuas rau lub plawv nres tshiab] cuam tshuam nrog ib feem ntawm cov hlab ntsha ntawm lub plawv, ua rau txo qis cov ntshav ntau cov pa oxygen mus rau lub plawv cov leeg.
Kuv puas ua rau ST nce siab lossis kev nyuaj siab?
STnce yog ib qho cim ntawm myocardial infarction los ntawm transmural ischemia. Txawm li cas los xij, cov txheej txheem ionic tsis tshua nkag siab piv nrog ST kev nyuaj siab pom thaum lub sij hawm subendocardial ischemia.
Pom zoo:
Puas yog myocardial infarction ua rau hypotension?
Txawm li cas los xij, nws tsis yog qhov tsis yooj yim uas muaj ntshav siab ntau ntxiv raws li cov nag lossis daus ntawm MI. Xwb, hypotension kuj tuaj yeem yog pom. Feem ntau qhov no qhia tau hais tias yog txoj cai ventricular MI los yog mob sab laug ventricular tsis ua haujlwm vim yog thaj chaw loj infarct lossis impaired thoob ntiaj teb plawv contractility.
Puas yog myocardial infarction tsis zoo yog lub plawv nres?
Ib qho tsis zoo ntawm myocardial infarction (MI) yog ib qho lub plawv nres lossis ua rau cov ntshav ntws mus rau lub plawvcov leeg uas cuam tshuam rau sab qis ntawm lub plawv. Inferior MI tshwm sim los ntawm tag nrho cov occlusion ntawm sab xis coronary artery nyob rau hauv 85% ntawm cov mob los yog sab laug circumflex nyob rau hauv 15% ntawm cov mob.
Puas yog myocardial infarction puas ploj mus?
Ib lub plawv nres, tseem hu ua myocardial infarction, tuaj yeem ua rau tuag taus, tab sis kev kho mob tau zoo tuaj ntau xyoo. Nws yog ib qho tseem ceeb uas yuav tau hu rau 911 lossis kev pab kho mob xwm txheej ceev yog tias koj xav tias koj yuav mob plawv.
Puas yog mob myocardial infarction?
mob myocardial infarction yog lub npe kho mob rau lub plawv nres. Lub plawv nres yog ib yam mob uas yuav ua rau muaj kev phom sij rau lub neej uas tshwm sim thaum cov ntshav ntws mus rau hauv lub plawv cov leeg raug txiav tawm sai sai, ua rau cov ntaub so ntswg puas.
Dab tsi yog septal myocardial infarction?
Lub septum yog phab ntsa ntawm cov ntaub so ntswg uas cais txoj cai ventricle ntawm koj lub siab los ntawm sab laug ventricle. Septal infarct tseem hu ua septal infarction. Septal infarct feem ntau yog ua los ntawm cov ntshav tsis txaus thaum lub plawv nres(myocardial infarction).
