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).
Dab tsi ua rau ST nce siab hauv txhua qhov kev coj?
Qhov tseem ceeb tshaj plaws ntawm ST ntu nce yog mob Ischemia. Lwm qhov laj thawj yog [4][6]: Kev rov ua dua tshiab. Mob pericarditis: ST elevation nyob rau hauv tag nrho cov coj tsuas yog aVR.
Vim li cas ST ntu tau nce siab hauv myocardial infarction?
Ib qho mob ST-nce myocardial infarction tshwm sim vim occlusion ntawm ib lossis ntau cov hlab ntsha, ua rau transmural myocardial ischemia uas ua rau muaj mob myocardial lossis necrosis.
ST elevation txhais li cas rau lub siab?
ST-Elevation Myocardial Infarction (STEMI) yog hom mob plawv mob hnyav heev thaum lub sij hawm ib qho ntawm lub plawv cov hlab ntsha loj (ib qho ntawm cov hlab ntsha uas muab cov pa oxygen thiab cov zaub mov- cov ntshav nplua nuj rau lub plawv cov leeg) raug thaiv. ST-segment elevation yog qhov txawv txav tau pom ntawm 12-lead ECG.
Puas yog ST nce siab hnyav?
Txhua lub plawv nres yog mob hnyav, tab sis ib hom yog qhov txaus ntshai tshaj plaws ntawm txhua tus thiab nws tau hu ua STEMI (ST ntu nce siab myocardial infarction), lossis tus poj ntsuam lub plawv nres..
