Ventricular depolarization (ua kom ua haujlwm) yog piav qhia los ntawm QRS complex, whereas ventricular repolarization yog txhais los ntawm interval los ntawm qhov pib ntawm QRS complex mus rau qhov kawg ntawm T- lossis U-wave. Nyob rau saum npoo ECG, ventricular repolarization Cheebtsam suav nrog J-wave, ST-segment, thiab T- thiab U-waves.
Lub sijhawm twg ntawm ECG yog cov ventricles Repolarizing?
Ventricular repolarization yog ib qho teeb meem hluav taws xob uas sawv cev rau theem tseem ceeb hauv kev ua haujlwm ntawm lub plawv. Nws tau nthuav tawm ntawm qhov chaw electrocardiogram los ntawm lub sijhawm nruab nrab ntawm qhov pib ntawm QRS complex thiab qhov kawg ntawm T yoj lossis U yoj (QT).
Dab tsi ntawm ECG qhia txog ventricular repolarization quizlet?
The ST Segment yog ntsuas los ntawm qhov kawg ntawm QRS mus rau qhov pib ntawm T yoj, thiab sawv cev rau ib feem ntawm ventricular repolarization. Cov ntu ib txwm yog feem ntau tiaj tus, lossis isoelectric.
ventricular repolarization pib qhov twg?
Hauv lwm lo lus, ventricular depolarization ib txwm pib nrog subendocardium (los yog endocardium) thiab kis thoob plaws lub ventricular phab ntsa mus rau epicardium, whereas lub repolarization pib ntawm lub epicardium thiab propagates rau subendocardium (los yog endocardium).
Qhov twg ntawm ECG kab yog cov ventricles cog lus?
ntu ST qhia thaum lub ventricle cog lus tab sis tsis muaj hluav taws xob ntws los ntawm nws. ST ntu feem ntau tshwm raws li txoj kab ncaj nraim, theem ntawm QRS complex thiab T yoj. T yoj qhia tau hais tias thaum lub plawv sab hauv qab tau rov pib dua hluav taws xob thiab npaj rau lawv cov leeg nqaij tom ntej.
