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.
