Ku xadgudubka hannaanka repolarization ah.

Xadgudubka repolarization protsesa - cillad ku xigta ee nidaamka wadnaha iyo, gaar ahaan - cudurada ka mid ah qayb ka mid tabinta iyo excitable unugyada wadnaha. isbedelka noocan oo kale ah waxaa lagu gartaa isbeddel ugu horrayn saameen ku electrocardiogram ah. Inta badan muujiyey repolarization xadgudub T negative (ama diyaarin at dusha) ilig ee raadad koowaad iyo labaad ee caadiga ah. Sawirka isku mid ah, wada jir ah ula an hoose isolines qeybta ST mowjadda lagu arkay hogaanka aVL iyo raadad precordial shanaad iyo lixaad.

Inta badan calaamadahan mid caan ku ah xanuunada aan shaqeynin of habdhiska u dabacsanaadaan, sida cardiomyopathy functional.

cardiomyopathy Tan waxaa lagu muujiyey sida xadgudub ku ah nidaamka repolarization of nudaha muruqa wadnaha (myocardium) in la bilaabo karaa xanuunada tabinta iyo dhaqdhaqaaqa garaaca wadnaha. habka repolarization Violation waxaa sababi kara koox weyn oo sababaya arrimood (etiological). arrimood oo dhan, kuwaas oo isugu afar kooxood oo ku salaysan dhibcood caadi ah in geeddi pathophysiology ah. Kooxdu waxay ugu horeysay - cudurada oo keeni in carqalad ah xeerka neuroendocrine ee habka wadnaha, oo ay ku jiraan habab ka mid ah cudurada of regulation potassium iyo heerarka catecholamine. Kooxda labaadna waxaa ka mid ah oo dhan lesions side iyo bararka ee unugyada muruqa wadnaha. Intaas waxaa sii dheer, geeddi-socodka repolarization daciif ah waxaa keeni kara dollar ah ama hypertrophy myocardial. Kooxdu waxay soo dhaafay waxaa ka mid ah cudurada sare taasoo keentay in la ballaariyo of QRS adag (laamaha Go'doominta ventriculonector, WPW syndrome).

xadgudub ugu badan ee habka repolarization ku yeesho sida hypersympathicotonia natiijo. cudurada Tani waxay u muuqato in ilmanimada hore iyo waxa lagu gartaa heerka korodhka hormoonnada (adrenaline iyo noradrenaliin) labanlaab marka la barbardhigo iska caadi ah. Intaa waxaa dheer, xadgudub repolarization ee myocardium ah waxaa keeni kara ma by heer sare oo ka mid ah hormoonada ee dhiigga, iyo kor u dareen in unugyada wadnaha si catecholamines. Sidaas darteed, in heerarka hormone caadiga ah, waxaa jira dhammaystiran muujiyay hypersympathicotonia sawirka kiliinikada.

Waxaa ka mid ah sababaha khaladaad in repolarization ee myocardium ah, saamiga ugu badan ee soo socda: cudurka wadnaha, hababka oo yaraada iyo isku xigxiga ee gmpertrofiya depolarization wajiga iyo cudura unugyada ventricular muruqa overvoltage oo Miisaaman elektrolytka (gaar ahaan - cudurada of sodium iyo dheelitirka potassium).

Koox gaar ah waxay ka kooban tahay sababaha aan u gaar ah. Dhab ahaantii, repolarization oo yaraada unugyada muruqa wadnaha ay dhacdo in la joogo ma jiraan joogitaanka arki karo on sababaha Ujeeddada. Xaaladdan oo kale, ogaanshaha iyo ogaanshaha kala duwan muu muujinin sababaha la taaban karo jirro.

cudurada noocan oo kale ah waa kuwo sii kordhaysa caadi ah in dhallinyarada ay qaan. Inta badan xanuunada kuwanu waa transient oo aadan u baahnayn daawayn. Si kastaba ha ahaatee, xataa ay ka maqan yihiin maamulka daaweynta bukaanada u baahan dhaqdhaqaaqa joogto ah xogta ECG. Daaweynta repolarization myocardial ugu horayn ku salaysan tirtiridda gaadhista factor ee sababaya, in uu yahay, daaweynta waa qof etiotropic.

Asal ahaan, daaweynta ka koobantahay medicaments adag ka kooban hormone, propranolol, panangina, cocarboxylase iyo vitamin diyaarinta kortikotropnogo. Si kastaba ha ahaatee, inta lagu guda jiro daaweynta cudurkan waxay u baahan tahay khasab baaritaan caafimaad oo ka mid ah bukaanka.
