Ekunene bundle block yesebe

Le kuvalwe iindlela block iinyawo zesebe bundle ekunene - abazifumene notyeshelo Uhanjiso le ventricles intliziyo. Senzeka ngo-0.2% abantu abatsha. Xa ubudala, lo rhoqo arrhythmia kwandisa ukuya 0,45%. Esi sifo phantse lonke kwenzeka kwisiqingatha iinkunzi yabemi.

Eyona nto ephambili leyo ebangela ukuba uphuhliso esi sifo sisifo sentliziyo ngexesha lesigaba oyingozi. Abantu kweminyaka engamashumi amane kuvalwe iindlela Umlenze wasekunene esiqhumeni bakhe ingozi, kuba akukho xhulumaniso abanala makhwiniba kwithishyu intliziyo. Kwezinye iimeko uphuhliso olu hlobo arrhythmia ikhuthaza lwegazi (60% yazo zonke iimeko). Kwiimeko ezinqabe kakhulu oko kubangelwa mgaqweni iziphene (hypoplasia seziqingatha ekuqaleni engabalulekanga). Kwakhona, ukuvela karhulumente ochaphazelekayo bubukho iziphene intliziyo: iziphene ventricular, iindonga atrial, ukuvala umlomo kwemithambo semiphunga. Thromboembolism wesingxobo, kunye obstructive umlinganiswa sisifo yemiphunga esingapheliyo kukhokelela yade le ventricle ekunene, oku kungabangela imbonakalo arrhythmias.

Ezibe negalelo kuphuhliso yile meko cardiomyopathy, amabele kwentlungu buthuntu, progressive muscular dystrophy, hyperkalemia, libanda, iziyobisi (novokainamidom, quinidine, glycosides kwentliziyo), utyando kule organ (ventrikulotomiya nkqo), nangezilonda kwentliziyo, syphiloma. Complete kuvalwe iindlela kunene isiqhuma semali kwisebe Ibloko clinical iimpawu zezifo eziye zabangela ngayo. Ezinye izigulane ibekwa utshintsho ngexesha auscultation: oqhekeza lokuqala (ngaphantsi aqhelekileyo), kwaye eyesibini ithoni (ivame kakhulu).

An electrocardiogram kubonakele ezi nqobo diagnostic zezi: ukwandisa isakhiwo ventricular, izinyo ophezulu R, nto leyo uyaqapheleka umkhondo yokuqala precordial, wona aqoqiwe R, njengoko kuchaziwe kwi ekhohlo ikhokelela izinyo ukuba unalo ixabiso ezahlukeneyo; elwayo kwicala S, ST.

Ekunene bundle isebe ibhloko, ukuphathwa ngayo, njengoko babonakale kakhulu, ayidingi ekhethekileyo amalungiselelo. Kananjalo ayidingi edokardialnoy ukukhuthazwa, nto leyo ngokwesiqhelo kwiimeko yenziwa ukuze zinqande kwimeko yentliziyo sokuhlaselwa. Ukuba kuyimfuneko ukuba unyango lwezifo, leyo kusoloko kukhokelela inkangeleko olu hlobo arrhythmia. Le kuvalwe iindlela ekunene bundle block yesebe, kwenzeka abantu kumaqela besebancinane, apho kungekho izitshanguba somgquba inyama kwentliziyo unalo ALS zangaphakath. umbono ekwanti le arrhythmia akanakuze ukuya ngokupheleleyo AB AB node kwamabutho.

Ngokutsho isifundo, bekusenzeka ngaxeshanye ezi ezimbi kukhokelela isiphazamiso kancane Uhanjiso ukusuka imithambo ukuya ventricles. Noko ke, ukuvuthuluka kwekhosi bezonyango le kwafa sifo kunye nokuncitshiswa la kwi ezimbaxa AB kunokwenzeka. Xa ukubanjwa olu hlobo arrhythmia ngqo lwegazi, kuba esi sifo intsonkothile kakhulu, lethality uba phezulu phantsi kwezi meko. Into esibi kuba phambi cardiomegaly, ukusilela intliziyo congestive, ixesha iSystolic zobude. Le kuvalwe iindlela yesebe bundle ekunene ngenxa kwi imvelaphi iposi engabalulekanga, phantse alize nasiphi arrhythmia enxulumene wokunyhashwa imisebenzi kwisiza AB. Ngoko ke, olu hlobo leengxaki iye phantse akukho inqanaba eliphezulu yokufa. Nangona kunjalo, ubukho iingxaki ezinzulu kwentliziyo, kungenzeka ukuba nzima kwaye bazixakekisa unyango lwabo, esenokuba ngokungasebenzi.
