Waa maxay socdaalka pacemaker ee atria ah?

socdaalka pacemaker ee atria ah - nooc ka mid ah arrhythmia wadnaha. Arrhythmia daawo loo yaqaan xadgudub ku ah wadnaha ah, taas oo lagu sheegi karaa sida kor u garaaca wadnaha, dardargelinta ama deceleration, ama qalbigaygu waa u dhawaaqaa in astaamaha aan caadi ahayn lagu arkay hoose qolal waxyaalaha qalbiga ku jira.

Qaar ka mid ah garaaca aqoonsado xaalad halis ah oo u baahan ka-qabashada caafimaad, halka kuwo kale ay yihiin kuwo aad u caadi ah oo sida caadiga ah ma keenaan sababta walaac. Xaaladaha intooda badan, dhacdooyin ah ee socdaalka pacemaker atria ah uma baahna daryeel caafimaad, laakiin haddii garaaca wadnaha oo aan caadi ahayn sababa walaaca bukaanka, waxaa ugu wanaagsan in la tasho dhakhtar si loo xaqiijiyo ammaanka gobolka.

farsamo ee socodka dhiigga

qalbigiisu wuxuu ka kooban yahay laba qolladaha sare (midig iyo bidix) iyo laba hoose (siday u kala horreeyaan intraventricular midig iyo bidix). Dhiig mara waddo adag u qeexaa iyada oo kaamirooyinka oo dhan, si loo hubiyo in wareegga caadiga ah ee ogsijiin iyo nafaqo jidhka oo dhan.

First, dhiig la mugga yar ee oxygen oo ka socda qaybaha kala duwan ee jirka sii daayo Atrium saxda ah, ka dibna la geeyaa ventricle midigta iyo gareeyeen si sambabada. Marka ay qaadanayso oxygen muhiim ah ka sambabada, dhiig qulqula bidix ah, ka dibna gelin ventricle bidix. Intaas ka dib, dhiigga oxygenated waxaa bixisey in dhammaan xubnaha kale ee gudaha iyo xubnaha jirka.

Doorka karsado ee korontada ku

Si aad u soo degayaa dhiig qolladaha dhexdoodana, muruqa wadnaha ayaa u baahan in la dhimay. In si kale loo dhigo, ka atria iyo intraventricular waxaa Tifaftirayaasha si loo hubiyo socodka dhiigga ee caadiga ah iyada oo wadnaha iyo jirka oo dhan.

Hoos u dhacaasi waxa ay gacanta ku falalkooda korontada ka imaanaya unugyada gaar ah oo awood u leh qabashada hadda iyo dira digniinta si unugyada kale. Waxay keeni hoos qolkii, ka dib markii laxanka gaar ah iyo inta jeer, sidaas bixinta socodka dhiigga caafimaad.

Guntin sinoatrial

Erayga "socdaalka pacemaker ee atria ah" waxaa si dhow la xiriira hawlaha ay koox ka mid ah unugyada ku yaal on top of Atrium saxda ah. Unugyada waxaa loo yaqaan sinoatrial (sanka) Guntin iyo ka masuul ah gacanta ugu soo noqnoqoshada iyo laxanka ah falalkooda korontada wadnaha ee jira. Sababtan awgeed, Guntin Dalqada wadnaha ku waxaa kaloo loo yaqaan pacemaker dabiiciga ah. Waxaa isaga u mahad bilaabay foosha wadnaha, ka dib markii laxanka gaar ah iyo inta jeer.

Guntin atrioventricular

Guntin Sinoatrial uma shaqeeyo keligeed - shuqulkiisa gacan ka noocyo kala duwan oo habab noolaha. Sayidka, ka falalkooda korontada ka kooxdan oo ah unugyada geli atrioventricular (atrioventricular) Guntin ah, oo ku yaalla yar oo qoto dheer qalbiga ka soo galay. Waxaa gudbiya signalka cabbaar socday, kuwaas oo la siinayo galo wadnaha, iyo sidaas, dhawra foosha synchronous muruqyada wadnaha.

socdaalka pacemaker ee atria ah

ilmaha ama dadka waaweyn waxaa laga yaabaa in arrhythmia gaar ah kuwaas oo gacanta ku qalbigiisa ku falalkooda korontada ka Guntin ku sinoatrial in atrioventricular dhaqdhaqaaqa.

socdaalka pacemaker ee atria ku dhacdaa waqti kasta, iyadoo aan loo eegin waxqabad, taas oo qof ayaa ku hawlan in waqtigan. Marka cudurka arrhythmia adag waxaa lagu diiwaangeliyaa sida inta lagu guda jiro tababarka ciyaaraha, iyo habeenkii.

Sida caadiga ah, oo ay joogaan waxaa ku dhowaad marnaba siinayaa sabab walaac. Xaaladaha qaarkood, waxaa jira xadgudubyo wadnaha yar, laakiin mararka qaarkood waxaa jira ma laha calaamado sida cudurada. Qofka si fudud ma aragto, goortuu ku yimaado socdaalka pacemaker ee atria ah.

sababaha halista

Noocan ah arrhythmia waxaa lagu gartaa in dadka da'da ah oo dhan, laakiin inta badan waxaa lagu arkay reer waayeelka iyo dhallinyarada. Socdaalka sidoo kale ma aha wax aan caadi ahayn loogu talagalay ciyaartoyda xirfadeed iyo kuwa jirkaaga taageero qaab ciyaareed fiican jirka. Sababaha la yaab ah weli la garanayn.

Xaaladaha intooda badan, dhakhaatiirta aan si cad u jawaabi karo waxa sababay guuritaanka pacemaker ee atria ah. Xaalado gaar ah, taas oo ah, marar aad u badan, xadgudub ku dhacdaa ka dib markii xad dhaafka ah ee glycosides wadnaha, loo isticmaalaa daawaynta cudurada wadnaha gaar ah.

Baadhista xanuunada

A socdaalka pacemaker caadiga ah ee atria ku ECG (electrocardiogram) si gaar ah u muujin. ECG habka natiijada iskaanka waa la mid taxane ah oo hirarka. sare ee la ruxruxo ka dhigan hoos u Atrium xaq u sababa Guntin ku sinoatrial. Haddii jaantuska jiro wax isdhaafin ah hirarka sida (isbeddel ah ee qaab, size iyo goobta), dhakhtarka ka dhigaysa ogaanshaha "socdaalka pacemaker ee atria ah."

Multifokusnaya tachycardia wadne-

Haddii aad ka shakisan tahay in aad qabto arrhythmia ah, ballan la sameyso dhakhtarkaaga si aad u sida "multifokusnaya (qasan), tachycardia wadne," ayuu culus cudurka sida ugu dhakhsaha badan ee suuragalka ah in la baabi'iyo. xadgudub Tani waa inta la mid ah in lagu tilmaamay in this article dhibaatada, laakiin qanjidhada wadnaha bilaabo falalkooda korontada ee noocan ah arrhythmia waqti isku mid ah. Sidaas darteed of function anomalous degdegsiimada garaaca wadnaha. Multifokusnaya tachycardia wadne-waa khatar oo u baahan daaweyn degdeg ah.
