Yintoni imfuduko ipacemaker le nomthambo?

Ntliziyo kwenye indawo kwe imithambo - uhlobo lwe arrhythmia intliziyo. Arrhythmia iyeza ekuthiwa ukugxojwa nokubetha kwentliziyo, leyo ungaboniswa njengoko ukwanda izinga lentliziyo, ukukhawulezisa okanye deceleration, okanye intliziyo izandi kwi iipatheni mgaqweni waphawula ezisezantsi emagumbini intliziyo.

Ezinye arrhythmias zinakanwa imeko enkulu efuna ungenelelo lonyango, ngoxa abanye zixhaphakile kakhulu kwaye ngokuqhelekileyo musa ukuba isizathu inkxalabo. Kwiimeko ezininzi, iziqephu lokufuduka ntliziyo imithambo musa kufuna unyango, kodwa ukuba ukubetha engaqhelekanga ebangela ixhala nomonde, kuya kuba kuhle ukuba udibane nogqirha ukuqinisekisa ukhuseleko karhulumente.

Indlela lokuhamba kwegazi

Intliziyo iqulathe amagumbi amabini aphezulu (ekunene kwaye intendelezo ekhohlo) kunye (ngokulandelelana ventricles ngasekunene nangasekhohlo) amabini asezantsi. Igazi asebenza ngendlela echazwe ngokungqongqo kuzo zonke iikhamera, ukuqinisekisa ukuhamba eqhelekileyo ioksijini kunye nezakhi wonke umzimba.

Okokuqala, igazi kunye umthamo amancinane oksijini kukhululwa ezivela kwiindawo ezahlukeneyo umzimba intendelezo ekunene, uze emva koko lungena ngokukhululekileyo ventricle ekunene ezimpontshelwa emiphungeni. Xa kuthatha ioksijini ebalulekileyo ukusuka emiphungeni, igazi elopha intendelezo olusekhohlo, uze kungena ventricle ekhohlo. Emva koko, igazi nomoya inikezelwa zonke ezinye izibilini amalungu omzimba.

Indima pulses zombane

Ukuze Achaphaze igazi phakathi kwamagumbi, imisipha intliziyo kufuneka lincitshiswe. Ngamanye amazwi, imithambo kunye ventricles ukuba zixinaniswe ukuqinisekisa igazi ukugeleza entliziyweni kunye umzimba uphela.

Ezi unciphiso zilawulwa zizimvo zombane evela kwiiseli ezithile ekwaziyo ukuqhuba kwaye thumela imiqondiso ukuba ezinye iiseli. Balala kwehle kwegumbi, kulandela isingqisho ethile kunye rhoqo, ngaloo ndlela, eyayinethombo legazi esempilweni.

node sinoatrial

Igama elithi "ipacemaker yokufuduka imithambo" ngokusondeleyo ukuya ekusebenzeni iqela leeseli ibekwe phezu intendelezo ekunene. Ezi seli ibizwa sinoatrial (sinus) esiludumbo kwaye onoxanduva lokulawula frequency nesingqisho neemvakalelo zombane intliziyo. Ngenxa yesi sizathu, esiludumbo sinus ukwabizwa ngokuba pacemaker yendalo. Kuyinto ngenxa kuye uqalise ucutheko kwentliziyo, kulandela isingqisho ethile kunye rhoqo.

node atrioventricular

node Sinoatrial ayisebenzi ngokwawo - umsebenzi wakhe negalelo ezahlukeneyo iindlela eziphilayo. Ngenxa yoko, amaza kagesi kweli iqela leeseli faka atrioventricular (atrioventricular) node, ibekwe nzulu kancinane entliziyweni. It adlulisele iimpawu ezikude, ewanika angene entliziyweni, yaye ngaloo ndlela, ogcina ucutheko yolunye kwemisipha kwentliziyo.

Ntliziyo yokufuduka imithambo

Umntwana okanye omdala inokuba arrhythmia ngqo apho ngamaza ombane ulawulo intliziyo ukusuka esiludumbo sinoatrial ukuya atrioventricular.

Ntliziyo kwenye indawo kwe imithambo nangaliphi na ixesha, kungakhathaliseki ukuba umsebenzi apho umntu waziphatha ngeli xesha. Xa arrhythmia kwesifo esimbaxa irekhodwa ngexesha loqeqesho ezemidlalo, yaye ebusuku.

Njengomgaqo, ubukho wayo phantse zange kwenani labo libangela inkxalabo. Kwezinye iimeko, kukho ezincinane ukwaphulwa intliziyo, kodwa maxa wambi akukho zimpawu enjalo ngezifo. nje Umntu akuthethi qaphela xa efika ipacemaker yokufuduka imithambo.

ubungozi

Olu hlobo arrhythmia banesifo abantu babo bonke ubudala, kodwa amaxesha amaninzi ngoko wazibona kubantwana abadala nabaselula. Imfuduko kwakhona akuqhelekanga kwiimbaleki zobungcali kunye nabo baxhasa umzimba wakho ukwimo elungileyo ngokomzimba. Izinto ezibangela le anomaly kuhlala ayaziwa.

Kwiimeko ezininzi, oogqirha Ubengemphenduli eziqhitsini yintoni eyabangela kwesincedisi- yokufuduka imithambo. Phantsi kweemeko ezithile, oko kukuthi, ngokufuthi kakhulu, lunyhasho kwenzeka emva libanda of glycosides kwentliziyo, ezisetyenziselwa unyango lwezifo ezithile sentliziyo.

ekuxilongweni

A pacemaker yokufudukela wendlela imithambo kwi-ECG (electrocardiogram) lubonakala ngokukhethekileyo. ECG indlela Iziphumo ukuskena efanayo kuthotho ngamaza. Umphezulu lencinibakazi limela ekunciphiseni intendelezo ekunene ezibangelwa esiludumbo sinoatrial. Ukuba mzobo kukho isitenxo lamaza ezinjalo (utshintsho imilo, ubungakanani kunye nendawo), ugqirha yenza une "ipacemaker yokufuduka imithambo."

Multifokusnaya tachycardia atrial

Ukuba ukrokrela ukuba une arrhythmia, yenza idinga nogqirha wakho ngokuba "multifokusnaya (ingalawuleki), tachycardia atrial," ihlamvu uxilongo ngokukhawuleza kangangoko kunokwenzeka ukuphelisa. Le ukuhlukunyezwa becala efanayo naleyo echazwe kweli nqaku le ngxaki, kodwa iindawo ezesifuba umkhwetha ngamaza ombane kule hlobo arrhythmia ngexesha elifanayo. Ngenxa yokuba umsebenzi anomalous olukhawulezisiweyo uVuyo. Multifokusnaya tachycardia atrial yingozi kwaye kufuna unyango ngokukhawuleza.
