Uyini kufuduka pacemaker we Atria?

Pacemaker yokufuduka le Atria - uhlobo arrhythmia inhliziyo. Arrhythmia imithi okuthiwa ukuhlukumeza we ukushaya kwenhliziyo, okungase wezwakalisa njengoba kwenhliziyo, ukusheshisa noma deceleration, noma inhliziyo umsindo e amaphethini okungajwayelekile nasemkhakheni aphansi emakamelweni inhliziyo.

Ezinye arrhythmias babhekwa njengabantu usesimweni esibucayi ezidinga kokungenela yezokwelapha, kuyilapho abanye ajwayelekile kakhulu ngokuvamile musa abangele isizathu sokukhathazeka. Ezimweni eziningi, ngezigameko kufuduka pacemaker le Atria angadingi ukwelashwa, kodwa uma ukushaya kwenhliziyo engavamile Kubangela ukukhathazeka nesineke, kungcono uye kudokotela uyofuna icebiso ukuqinisekisa ukuphepha isimo.

Mshini wegazi ukugeleza

Inhliziyo siqukethe emakamelweni amabili engenhla (ngakwesokudla futhi ATRIUM kwesokunxele) kanye (ventricles sokunene nesobunxele ngokulandelana) ezimbili aphansi. Igazi kugeleza umzila ngokuqinile kuchazwe ngokusebenzisa zonke amakhamera, ukuqinisekisa ukuzungeza evamile mpilo nezakhi zawo wonke umzimba.

Okokuqala, igazi esinevolumu sakugcina-mpilo ezikhishwe ezivela ezingxenyeni ezihlukahlukene zomzimba zibe ATRIUM kwesokudla, bese ugelezela i-ventricle yangakwesokudla Ziphampa emaphashini. Uma kuthatha umoya-mpilo obalulekile ovela emaphashini, igazi agelezela ATRIUM ngakwesokunxele, bese ku-ventricle engakwesobunxele. Ngemva kwalokho, igazi nomoya-mpilo ihlinzekwa ukuba zonke ezinye izitho zangaphakathi nezitho zomzimba.

Indima pulses kagesi

Ukuze distill igazi okwakuphakathi kwamakamelo, imisipha yenhliziyo kufanele encishisiwe. Ngamanye amazwi, lo Atria futhi ventricles ziya onomfutho ukuqinisekisa evamile igazi ukugeleza ngokusebenzisa inhliziyo futhi umzimba wonke.

Lokhu kwehla zilawulwa amaza kagesi ivela amaseli ethize uyakwazi kokuqhuba zamanje bese uthumela izimpawu kwamanye amangqamuzana. Tibangela ukunqabela ekamelweni, kulandela isigqi ezithile futhi imvamisa, ngaleyo ndlela linikeze ukugeleza kwegazi enempilo.

node sinoatrial

Igama elithi 'pacemaker yokufuduka le Atria "lihlobene eduze negama ukusebenza iqembu amaseli esisogwini phezulu ATRIUM kwesokudla. La mangqamuzana abizwa sinoatrial (itheku) node kanye banesibopho ukulawula nobuningi nesigci inkanuko inhliziyo kagesi. Ngenxa yalesi sizathu, engeyokuqala itheku ubizwa nangokuthi pacemaker zemvelo. Kuyinto ngiyabonga kuye okuqalwe ukusikwa inhliziyo, kulandela isigqi ezithile futhi imvamisa.

node atrioventricular

node Sinoatrial akusebenzi ngokwalo - umsebenzi wakhe neqhaza ezihlukahlukene izindlela begazi. Ngakho, amaza kagesi kuleli qembu lamaseli faka atrioventricular (atrioventricular) node, elise kancane ujule inhliziyo. It okuhambisa amasignali phambidlana, babanike ukungena inhliziyo, futhi ngaleyo ndlela, igcina ukusikwa zokuvumelanisa of imisipha yenhliziyo.

Pacemaker yokufuduka le Atria

Ingane noma umuntu omdala kungaba arrhythmia ethize lapho ukulawula inhliziyo amaza kagesi babesuka engeyokuqala sinoatrial kuya atrioventricular.

Pacemaker yokufuduka le Atria kwenzeka nganoma isiphi isikhathi, kungakhathaliseki ukuthi umsebenzi lapho umuntu waziphatha ngalesi sikhathi. Lapho eziyinkimbinkimbi arrhythmia uphethwe liqoshwe njengombhali phakathi nokuqeqeshwa ezemidlalo, futhi ebusuku.

Njengomthetho, khona layo cishe asikuniki isizathu sokukhathazeka. Kwezinye izimo, zikhona ezincane ukwephula inhliziyo, kodwa ngezinye izikhathi azikho izimpawu ezinjalo zokugula. Umuntu nje akusho ukuqaphela lapho efika pacemaker yokufuduka le Atria.

engcupheni

Lolu hlobo arrhythmia sitholakale kubantu babo bonke ubudala, kodwa ngokuvamile iningi it is ebonwe asebekhulile futhi abasha. Ukufuduka futhi kuvamile ukuba abadlali professional kanye nalabo abasisekelayo umzimba wakho isesimweni esihle ngokomzimba. Izimbangela anomaly ayikaziwa.

Ezimweni eziningi, odokotela abakwazi ukuphendula ngokungananazi ukuthi yini eyabangela abantu ukuthuthelwa pacemaker we Atria. Ngaphansi kwezimo ezithile, okungukuthi, kaningi, ukuhlukumeza kwenzeka ngemva ukweqisa izidakamizwa of glycosides inhliziyo, esetshenziselwa ukwelapha izifo ezithile senhliziyo.

ukuhlola

Ukudla okuvamile pacemaker yokufuduka le Atria phezu ECG (electrocardiogram) lubonakala ikakhulu. ECG Imiphumela ukuskena indlela iyafana uchungechunge amagagasi. Phezulu wave limelela ilungelo ATRIUM ukunciphisa kubangelwa engeyokuqala sinoatrial. Uma umdwebo kukhona ukuzwe amagagasi anjalo (izinguquko ijamo, ubungako kanye nendawo), udokotela kwenza sitholakele 'pacemaker yokufuduka le Atria. "

Multifokusnaya tachycardia atrial

Uma usola ukuthi une-arrhythmia, wenze sibonane nodokotela wakho ukuze ahlole njengoba "multifokusnaya (kunezinxushunxushu), tachycardia atrial," olunesisindo esikhudlwana lwaluba uphethwe ngokushesha ngangokunokwenzeka ukuze kuqedwe. Lokhu ukuhlukumeza ngokuyinhloko okufana nalokho okuchazwe kulesi sihloko inkinga, kodwa ISIZINDA inhliziyo ukuqalisa amaza kagesi kulolu hlobo arrhythmia ngesikhathi esifanayo. Ngenxa yalokho umsebenzi ezingasadingeki yashesha ukushaya kwenhliziyo. Multifokusnaya tachycardia atrial liyingozi futhi zidinga ukwelashwa ngokushesha.
