Lub xub ntiag ntawm thaum ntxov repolarization (ER) tus qauv hauv 12-txhuas ECG , txhais tau tias nce siab ntawm QRS-ST kev sib tshuam (J point) feem ntau cuam tshuam nrog QRS lig dhau los lossis thais (J nthwv dej), yog ib qho kev pom tshwm sim hauv cov pej xeem, tshwj xeeb tshaj yog nyob qis qis thiab ua ntej ib sab.

Los ntawm qhov ntawd, puas yog kev rov tsim dua tshiab thaum ntxov txaus ntshai?

Thaum ntxov repolarization Syndrome (ERS), pom tau tias yog J-point elevation ntawm electrocardiograph, yav tas los xav tias yog ib qho chaw zoo, tab sis cov kev tshawb fawb tsis ntev los no tau pom tias nws tuaj yeem cuam tshuam rau kev pheej hmoo ntawm lub neej - hem arrhythmias thiab kev tuag sai sai (SCD.).

Ib yam li ntawd, dab tsi ua rau benign ntxov repolarization? Nws tau kuaj pom raws li qhov nce J-point / ST nce qhov twg ST ntu tau txuas nrog. Nws ntseeg tias yog ib qho kev hloov pauv ib txwm muaj. Benign ntxov repolarization uas tshwm sim hauv qis dua thiab ib sab ntawm lub plawv cov leeg yog cuam tshuam nrog ventricular fibrillation.

Yog li ntawd, dab tsi yog lub ntsiab lus ntawm repolarization thaum ntxov?

Thaum Ntxov Repolarization yog lo lus siv ib txwm siv rau ST ntu nce yam tsis muaj kab mob. Tej zaum nws tsis muaj dab tsi ua nrog qhov tseeb ntxov repolarization . Feem ntau pom nyob rau hauv cov tub hluas. Nws yog ib qho tseem ceeb kom paub qhov txawv thaum ntxov repolarization los ntawm ST ntu nce los ntawm lwm yam ua rau xws li ischemia.

Repolarization txhais li cas hauv plawv?

Qhov kev tshwm sim zaum kawg ntawm lub voj voog yog cov repolarization ntawm lub ventricles. Nws yog lub restoration ntawm lub xeev so. Hauv ECG, repolarization suav nrog J point, ST ntu, thiab T thiab U nthwv dej. Qhov transthoracically ntsuas PQRS feem ntawm electrocardiogram yog qhov tseem ceeb cuam tshuam los ntawm lub paj hlwb sympathetic.
