Ntawm T-wave Physiology Ib txwm T nthwv dej yog upright nyob rau hauv leads I, II, thiab V3-V6, inverted nyob rau hauv AVR. Tsawg tshaj li tsib hli hauv qhov taw qhia, tsawg dua kaum hli hauv cov thawj coj ua ntej, thiab kev nthuav qhia sib txawv hauv III, AVL, AVF, thiab V1-V2.
Yuav hloov pauv T yoj tuaj yeem yog qhov qub?
T-wave hauv V1 tuaj yeem hloov pauv ib txwm nyob rau txhua lub hnub nyoog thiab hauv V 2nws qee zaum ib txwm tsis zoo[5]. Feem ntau, T-yoj tsis zoo hauv kev coj aVR, V1 thiab III.
Puas yog T wave inversion ib txwm nyob hauv AVF?
Feem ntau, qhov hloov pauv T nthwv dej hauv ib qho txhuas txhuas hauv ib ntu anatomic (piv txwv li, qis dua, sab nraub qaum, lossis sab hauv) tsis zoo li sawv cev rau cov kab mob hnyav; Piv txwv li, ib qho kev hloov pauv T yoj nyob rau hauv ob qho tib si lead III lossis aVF tuaj yeem yog qhov txawv txav.
Yuav ua li cas hloov T yoj ntawm ECG qhia?
Txawm hais tias qhov tseeb no, qhov hloov pauv T nthwv dej hauv qhov chaw kho mob keeb kwm tsim nyog yog qhov qhia tau zoo ntawm ischemia Ischemia tuaj yeem yog vim muaj tus mob coronary mob tshwm sim los ntawm kev tawg ntawm atherosclerotic. Cov quav hniav los yog vim muaj qhov ua kom cov pa oxygen xav tau lossis txo cov pa oxygen xws li mob ntshav qab zib hnyav lossis sepsis.
Puas yog T yoj inversion hauv aVL ib txwm?
Results. T yoj inversion nyob rau hauv aVL tau txheeb xyuas nyob rau hauv 89 ECGs (46.8%) nrog meej ischemic Q-ST-T hloov nyob rau hauv txawv leads nyob rau hauv 97 ECGs (50.8%). Sawv ib leeg aVL T yoj inversion tau pom nyob rau hauv 27 ECGs (14.1%) thaum ischemic hloov nyob rau hauv lwm yam kev coj nrog ib txwm aVL raug txheeb xyuas nyob rau hauv 36 ECGs (18.8%).
