Laxanka sanka kala duwan sida

Jawaabta su'aasha ah: "Waa maxay laxanka a sanka caadiga ah" bilaabaa in uu silcin inta badan dadka ku nool dejinta cudurka gaar ah. Illaa markan sifooyinka functional qalbiga ma waxaa ka mid ah xiiso gaar ah. article faahfaahsan tixgelin Tani waxay noqon xiran laxanka sanka doonaa.

Normal shaqada wadnaha waxaa bixiya saddex hawlood: excitation, automatism iyo conductivity. weecasho kasta oo ka soo hawlgalka caadiga ah ee qaababka waxay keenaan horumarinta noocyada kala duwan ee garaaca. heerka A wadnaha caadi ahbaa in Guntin Dalqada wadnaha iyo waxaa lagu magacaabaa laxanka sanka. Dhakhtarka wadnuhu at account cudurka for xaqiiqda ah in laxanka sanka ma aha had iyo jeer tilmaame hawlgalka saxda ah ee wadnaha, qaar ka mid ah cudurada wadnaha dhici aan garaaca wadnaha. In dhallaanka dhashay, ah laxanka la dedejiyey sanka, gaadhaya 150 garaac, loo arkaa wax caadi ah.

Wadnaha, samaynta rikoor on cardiogram 'laxanka sanka ah. Norma ", ayaa maskaxda ku soo socda:

• adag QRS ayaa la ruxruxo P of qaab joogto ah;
• laxanka heerka garaaca wadnahaaga ee 60-80 waa garaaca;
• Distance P-P ama R-R identically.

Erayga "xanuunada laxanka sanka" waxa loola jeedaa in garaaca iyo Cunaqabtayntaas. habowga kasta oo ku soo noqnoqoshada, joogto ah oo joogta ah ee arrhythmia wadnaha yeedhay. block Heart la baryo marka tabinta ka jabay ee excitation xarunta si toos ah u muruqa wadnaha.

Garaaca meesha of wadnaha qaybsan dissonance shaac baxa intraventricular iyo intraventricular u kacay in ka badan. Ka mid ah dhakhaatiirta soocidda soo socda waa la qaatay, oo muujineysa laxanka sanka deganayn:

1. dissonance qaabeynta garaaca wadnaha

• Dissonance la xidhiidha xad-gudub ku ah automatism, oo ay ka mid tachycardia sanka, bradycardia, garaaca,
• Dissonance la xidhiidha Lagaga ee automatism: garaaca gaabis ah ama la dedejiyey, ama doorasho dhexe, marka xaddiga garaaca wadnaha caanuhu iyo dadajiyaa ilaa (xadgudub ku ah pacemaker ah);
• Dissonance la xiriira dhicitaanka soo noqnoqda ee kacsiga.

2. Dissonance tabinta, waayo, noocan oo kale ah waxaa ka mid ah xadgudubyada oo dhan cayn kasta oo go'doominta.

3. xadgudubyada lagu daro

Waayo, cudurka dhakhtarka u baahan yahay si aad u ogaato taariikhda caafimaad ee bukaan-socodka, si aad u hesho xogta waxbarashada xarkaha iyo caafimaadeed. Marka ururinta wadnaha taariikhda isku dayi doonaa si aad u hesho warbixin ku saabsan joogitaanka caadooyinka xun, hiddo iyo cudurada wareejiyo. Dhakhtarku waxa uu ku weydiin doonaa marka ugu horreysa ee bukaanka waxay dareemeen in laxanka sanka ka jabay, waxa dareenka uu soo maray halka. Xogtan ayaa kaa caawin doontaa in la go'aamiyo nooca xanuunada: ah laxanka sanka dedejiyey in bukaanka ama qeybsanaan ah, gaabis ah. Inta badan, dadka bukaanka ah ka caban of raaxo ee gobolka wadnaha, dareenka Ujeedada ama shakhsi ahaan carqalad waxyaalaha qalbiga ku jira (xawaaraha ama deceleration). Mararka qaarkood garaaca gudbin kartaa dareemo by bukaanka iyo waxay keeni kartaa in miyirka oo luma. Arrhythmia arrin inta badan la socda neefta oo ku qabata, yalaalugo, daciifnimo. Depression dhaqdhaqaaqa wadnaha saameeyaa hawlaha caadiga ah ee qaabka neefsashada, taas oo horseedaysa la'aanta oxygen.

Help in garaaca ogaado ayaa ECG, iyo daaweynta daawada kaa caawin kara in la yareeyo calaamadaha xun ee cudurka. Haddii inta lagu guda jiro garaaca astaamo, therapy daroogada aan looga baahan yahay ilaalinta qiimaha caadiga ah ee wadnaha iyo ilaalinta ee shaqada contractile ay. Haddii garaaca saamayn hawlaha caadiga ah, daaweynta ugu weyn waxaa loogu talagalay in lagu abuuro jeeda elektrolytka fiicnayn la magacaabay diyaarinta gaar ah. Haddii arrhythmia u keeni kartaa dhimasho of bukaanka, dhakhaatiirta qalliinka loo isticmaalo artafiishal. Qaar ka mid ah noocyada kala duwan ee garaaca waxaa lagu daaweeyaa by yahay qaliin.
