Heart pacemaker: ngokusebenza iindleko, ukubuyekeza

Umzimba womntu rhoqo ekhula, uninzi izibilini ubudala, banxibe. Kungenxa yoko le nto imiyalezo ezayo intlungu esilumkisa ukuba ezinye umzimba inika ukungasebenzi. Noko ke, intliziyo yomntu abaza kujolisa kuso. ixhala ngempilo yakhe iintlungu ngentliziyo okanye ubunzima esifubeni wadala. Njengoko iyaziwa, intliziyo esempilweni - ubomi obude.

Ngelo xesha langoku iyeza senza konke mpumelelo ezintsha entsimini yamayeza, ngoko ke bonke khangela intliziyo yabo ukuchonga izifo ezithile. izixhobo zovavanyo High-ngqo ukufumana indlela eye yahluleka, ngoko ugqirha wakho aya kuyinyula unyango olungcono kunye olufanelekileyo. Enye yezona best ulungiso ukhetho kunceda kwakhona umsebenzi intliziyo elahlekileyo yi-ntliziyo kwentliziyo. Operation, ukubuyekeza apho eyona entle, wenza kude nezigulane zangaphambili, into ebuhlungu. Baphila ubomi ngokupheleleyo. Cardiology eMoscow sise kwelona nqanaba liphezulu. Kulo nyaka waphilisa amashumi amawaka abantu abadala kunye nabantwana, kunye noogqirha best kunika abahlali yelizwe ubomi entsha ngokupheleleyo.

Kodwa ngaphambi kokuba uqonde into ipacemaker kwentliziyo (iindleko umsebenzi inokuba nomahluko) kwaye isebenza njani, kufuneka ukwazi nokwakheka amalungu omzimba, njengentliziyo.

Intliziyo: isakhiwo sayo kunye nokusebenza

Intliziyo - ilungu dystrophy ukuba ikwazi ukumpompa igazi wonke umzimba. Kuyo na isahlulelo ebandakanya esiqwini kwezihlunu ukuba yahlula intliziyo ibe yinxalenye ekhohlo ne ekunene. Ezi ndawo zimbini nabo ezahlulwe sisithuba isahlulelo, kwisiqingatha ephezulu ekuthiwa imithambo, kwaye ephantsi - i ventricles. Imithambo kunye ventricles idityaniswe kwezivalo komzimba apho igazi ehamba imisipha.

Igazi, ngelixa Icala lasekunene intendelezo engena emiphungeni apho uchola ioksijini ngenkuthalo. Ngaphezu koko, eli gazi engena ventricle olusekhohlo, uze lungena ngokukhululekileyo aorta, nto leyo lahlulahlulwe umthambo. Ngenxa lo matshini lokumpompoza igazi ioksijini eninzi kuwo wonke umzimba ngenxa yegazi ngoko elicebisa zonke izicwili kunye namaziko oksijini. Emva kokuba umsebenzi bahlehla mpilo abulawe, igazi buthathwa emithanjeni kwaye akukanikwa ngxelo ngazo entliziyweni, kuqala nghena intendelezo ekunene, uze kungena ventricle ekunene. igazi lwemithambo Igcwele ioksijini, kuya kuba lula ngakumbi lwemithambo.

Ngenxa yokuba intliziyo yomntu esebenza kakuhle, igazi uyakwazi kuqhutyekwe nokuqhamisa ikharityhulam ye-izondlo neoksijini bonke ancedisana amalungu. Indlela zendalo ufumana intliziyo kwaye yenza ukumpompa igazi, isekelwe phezu unikezelo neemvakalelo ezizodwa zombane. Xa amayeza, lo msebenzi kuthiwa esiludumbo sinus, intliziyo zendalo okanye umqhubi. Le isembindini, oko kukuthi, i-Icala lasekunene inxalenye yakhe intendelezo.

Sinus node ludlala indima ebalulekileyo kumsebenzi kwentliziyo. Ilawula izinga intliziyo, yaye ngokuxhomekeke meko kunye neemeko ezahlukeneyo ibalekisa umyinge intliziyo, okanye ngenye indlela ukuba wehlise kubo. Umzekelo, ukuba usebenzisa intliziyo ibetha ngamandla urhulumente angenzi nto eziphilayo. Intliziyo yendalo uvakalelwa umqhubi ukuba kukho imfuneko yokumpompa igazi ngokukhawuleza, ngoko imisipha intliziyo isakha kwakhona umqhubi isantya ngakumbi olukhawulezisiweyo umsebenzi.

electroimpulses zokuhambisa indlela

Andise pulses ombane kufezwa kukuba ilahlwe kufuphi imicu conductive, yaye babangela imithambo kunye ventricles kwisivumelwano phambi kokuba ubume elandelayo. Ngenxa lekhefu phakathi kwamathumbu, nto leyo ukumelana intliziyo, kukho "Ezinye" kwemisipha kwentliziyo.

Phantsi kweemeko ezithile nokomzimba kwaye zophendlo lwezifo ze izinga kwentliziyo zehlile. Izizathu ngenxa leyo imenza nokubetha kwentliziyo:

• nesiyezi;
• wegazi;
• intloko ebuhlungu;
• ukudinwa, silale;
• niphele;
• sokuquqa ukusilela sokuphefumla.

Xa iyeza, imeko ekuthiwa bradycardia. Isizathu sokuba livela kukuba kukho ngokoyiswa esiludumbo sinus, elandelwa utshintsho kwinkqubo Uhanjiso. Loo imeko kukhokelela ekuncipheni nezihlandlo izinga lentliziyo, nto leyo echaphazela inkqubo sentliziyo umzimba uphela, kuba lunciphisa ioksijini ukuya ancedisana amalungu. Kamva iphuhlisa anoxia, yaye le meko ikhokelela kakuhle amalungu amaninzi kakhulu. Kwindawo yokuqala iqala ukubandezeleka intliziyo ngokwayo. Isigulane banokuziva iintlungu esifubeni, kwakunye ubungqongqo kwentliziyo. Ukuba umntu akanayo ingqalelo le iimpawu yaye musa azisinyangi isifo, oko ke iqala ukubandezeleka i ingqondo, okanye mandithi neeseli zobuchopho, leyo ngamaxesha zifuna eliphezulu oxygen kufumaneka bantu.

Ngophuhliso block intliziyo amaza ungenisa esiludumbo sinus ayisoloko kwandise ukuya ventricles, yaye ngamanye amaxesha musa ukufikelela, nto leyo ekhokelela ukuba ukuphazamiseka imithambo operation yolunye kunye ventricles.

Pathology ukusebenza izinga intliziyo

Bekhubazekile ukuphazamiseka isingqi intliziyo enxulumene ngezifo kwenkqubo sentliziyo womntwana, oko kukuthi nokubekwa phantsi emzimbeni utshintsho ayibuyiseki (isifo sentliziyo). amaxesha amaninzi ukuhlukumeza loo umiselwa ultrasound uphando ezingekazalwa, kodwa ngamanye amaxesha sifo eshiyekileyo ifunyanwa kuphela emva kokuzalwa wosana olo.

nezifo zentliziyo ujongene yabantwana, kunye nonyango kids, owafumana imikhuba zentliziyo, ngamanye amaxesha kuyimfuneko ukuba wazisa emzimbeni ntliziyo ukuze asindise ubomi bomntwana.

Ukophulwa izinga intliziyo ezifunyenwe lunokwenzeka ngenxa yezizathu ezininzi:

• utshintsho ubudala;
• emva iqhosha le izihlunu intliziyo;
• izifo ezosulelayo, anika ingxaki entliziyweni;
• yofuzo;
• ukutyeba;
• ukutshaya kunye nokusetyenziswa kakubi kotywala.

Ukubuyiselwa kwesingqisho intliziyo

Esi sifo kwezonyango singanyangwa, iziyobisi isuswe mpawu kuphela, kodwa impilo isigulane iselelona emngciphekweni. Kule meko kuyacetyiswa ukuba kusetyenziswe pacemaker ngumntu. It is a iyunithi eyodwa - ipacemaker eyenza abaphulaphuli pulses kwentliziyo kakuhle, ibangela imithambo kunye ventricles sincipha synchronously. Ukuze ufake ipacemaker wentliziyo, iindleko msebenzi liya kuba phezulu kwaye iya kuba ixesha ekuphulukenwe nzima ngakumbi, ukuba esi sifo singanyangwa ngexesha, yaye ukuba oko ithuba.

Ukwakhiwa kwenkqubo pacemaker yombane

Indlela esakhiwe ngayo esi sixhobo inzima kakhulu, ukuba ibekwe khona izindlu etywiniweyo kwaye iquka ukubetha kwentliziyo generator ne electrode. Izindlu ibandakanya ingxubevange ezizodwa zonyango (titanium), nto leyo eyandisa elingama ivuselela ebantwini.

Ukusebenza yunithi lwenziwa kuphela kwezo zihlandlo, xa uqala i yabetha intliziyo kade, okanye kuvela ikhefu kumsebenzi kwentliziyo. Kulo mzekelo, ifowuni isebenza indlela, ethumela ngamaza ombane ukuya imisipha kwentliziyo yakhe, kwadala isimo yayo yesiqhelo. Lo mzobo engumzekelo wendlela-ntliziyo. iimpendulo nokusebenza izigulane ngezifo kwentliziyo, wafumana HIV. Baya ubilisa phantsi yokuba izigulane andimvumeli ngaphezulu intliziyo isingqi disorder, abuyele bubomi obuqhelekileyo.

iintlobo

Okwangoku, kukho iintlobo ezintathu izixhobo, ezo pacemaker ngumntu.

1. Single-egumbini pacemaker. Ngaba electrode omnye kuphela, nto leyo imi ventricle, ziye kuphela igumbi elilodwa inhliziyo. nokuncipha Atrial koko wenziwe ngendlela yemvelo. Olu hlobo izixhobo amaphutha ezinzulu, njengoko ababeki-liso kwentliziyo omnye gumbi kuphela. Ngamanye amaxesha kuyenzeka ukuba ngenxa yale isingqisho efanayo ventricular fibrillation, nto leyo ekhokelela ukuba igazi flow okungaqhelekanga ngokusuka entliziyweni. Ngenxa kakuhle igazi atrial akayi kuba nako ukuhamba ngokupheleleyo ukusuka ventricle ukuya intendelezo, ngoko ke akayi nzulu egazini.
2. I-mbini egumbini pacemaker. Kuye electrode ezimbini, enye ibekwe kwi ventricle, kwaye eyesibini - kule intendelezo. Le fowuni ine amancedo ipacemaker elinye-gumbi. Kulo mzekelo, kukho ulawulo ngokupheleleyo ukusebenza echanekileyo intendelezo ungqamaniso epheleleyo kunye ventricle. Ngenxa nencindi igazi entliziyweni liya kuqhubeka ngaphandle neziphithiphithi, igazi kuya kumpompoza xa egazini imithetho ezelwe, njengoko kwakunjalo msebenzi esempilweni inhliziyo.
3. Three-zawo pacemaker. Esi sixhobo yokufakelwa ngumqhubi izinga intliziyo eziphambili. Kuye electrode ezintathu, nto leyo ibekwe entliziyweni namacandelo amathathu: intendelezo, lo ventricle ekhohlo nasekunene. Ngenxa kwindawo qhinga ezifana physiologically igazi echanekileyo udlula onke amanqanaba kwigumbi kwentliziyo omnye engenayo kwenye, Esiwa kakuhle ezityeni yegazi. Kwisingqi ngexesha elifanayo iyafana naleyo yintliziyo esempilweni.

Yintoni i electrode, kwaye isebenza njani kule kwesincedisi-

Ngenxa bungqingqwa eliphezulu electrode xi nga ukugoba lula kwaye twist, nto leyo ibaluleke kakhulu kwisixhobo enjalo, njengoko kukho iintshukumo zomzimba ezahlukeneyo umntu, kwakunye nezinga intliziyo. Umqhubi iyakwazi yokudlulisela pulses myocardium ivelisa apho ulwazi izinga intliziyo. I electrode sinentloko ekhethekileyo ultrasensitive, nto leyo idala umfowunelwa kunye imisipha ngentliziyo.

Heart pacemaker: ngokusebenza, izigxeko

Kweli nqanaba ukuqaliswa nokusebenza ipacemaker na inkqubo elula kulula. It awutsali ngaphezu kweeyure ezimbini, uqhutywe ngoogqirha abanamava liSebe - zentliziyo. Izimvo yezigulane kwixesha postoperative ezilungileyo, kuba angalulama ngokukhawuleza, yaye kungekudala izigulane ziya angasuswa ekhaya. Ntliziyo athungwe kwizikhongozelo kwindawo subclavian ukwenzela ukuba phakathi eluswini kunye izihlunu zomzimba.

Electrode kufuneka, phambi kokuba ungene em- intliziyo, ucanda umendo Kwangale. yonke Inkqubo electrode placement lwenzeka kugadwe ultrasound. Yi inxalenye olungaphandle kwicandelo kwentliziyo Iqinisekile idivayisi uqobo - kwesincedisi- intliziyo. Ukubuyekezwa Nokusebenza izigulane abazibandakanyileyo ipacemaker ngumntu, wamkela HIV. kungekudala Enkosi olwenziwe betyale ukuze angene indlela yakho yangaphambili yobomi. Kodwa ke, kusekho ngokuphazamisa neentsilelo ahlale. Kodwa umzimba yaziswa isixhobo esinzulu kakhulu - ipacemaker kwentliziyo. Iindleko ukusebenza ixhomekeke nomvelisi wesixhobo eso kunye nezinto electrode.

imithetho yokusebenza

Ukuze ukuba kukho sohlolo kwinkqubo ipacemaker oluzenzekelayo, kufuneka zilandele ngqo le migaqo ilandelayo:

• asikho kufutshane imigca amandla ombane aphezulu;
• Akuvunyelwe ukuba abacwangcisi ngeenxa ezahlukeneyo amandla, iinqaba ukudluliselwa iisignali zerediyo kunye TV;
• Xa kungekho tyala ayikwazi kuhlolwa a kakutsha yesinyithi (kwisikhululo seenqwelo-moya, ezivenkileni).

Phambi kwesincedisi- olungisiweyo akuvumelekanga ekuyigqithiseni uphando lwezonyango:

• Ultrasound esifubeni;
• MRI (research);
• unyango fiziokabinete e Amanzi kwamaza ezahlukeneyo: unyango magnetic, electrotherapy;
• electrocoagulation kuphela imvume gqirha khona.

Kubomi bemihla ngemihla kufuneka bathobele imithetho ethile;

• Kuphephe uthinte umthombo wombane;
• musa ukuhamba kumatshini yabo, ambetha;
• ukuthetha iselfowuni, wabeka indlebe yokunene;
• usebenzisa umthwalo, drill kufuneka silumke kunene;
• ukuba zizame izihlunu esifubeni;
• ku ejimini ukunciphisa umthwalo kweli qela izihlunu.

Iindleko zokusebenza kunye nexabiso kwesincedisi-

Ngokuqhelekileyo, xa umsebenzi intliziyo iindleko iquka yena pacemaker. Ngenxa yoko, inani lokugcina sakhiwa iseti iinkqubo kunye nemisebenzi. Ezi ziquka:

• uqhaqho ngenhliziyo evulekileyo;
• iindleko pacemaker;
• electrode ixabiso;
• ixesha lokuhlala kweli zentliziyo, kwimeko yesiqhelo.

Kubalulekile ukuqinisekisa ukuba uhlobo ipacemaker, njengoko liye electrode leyo umenzi. Ngokuxhomekeka oku, ngexesha iindleko uqhaqho lwentliziyo ziyahluka ukusuka mncinane ukusa kakhulu ngokuqinisekileyo phezulu. Le lentengo pacemakers:

• isixhobo Uhlobo egumbini eyodwa (imveliso yasekhaya) ka-10 500 ukuya 55 000, ngenisa - 80 000 engange;
• egumbini kabini - ukususela 80 000 ukuya kuma-250 000 engange; yokungenisa Togu - evela engange 250 000;
• ezintathu-zawo - 300 000 nangaphezulu, kwaye ngaphandle umlinganiselo 450.000 engange.

Nangona kunjalo, oku kufuneka kucaciswe ukuba oku akubandakanyi ixabiso i electrode. Ixabiso electrode zasekhaya ziya kuba ukususela engange-2000 ukuya 4500, ungenise - ukususela 6000 engange. Ngoko ke Kulula ukubala malini lubekelwe kwesincedisi- wentliziyo, iindleko msebenzi iya kuba kwi-15 000 ukuya 500 000.

pacemaker ukufaka

Cardiology Centre ise elikomkhulu, ngoko elinyanga abemi izixeko ezahlukahlukeneyo kweli lizwe.
Eli ziko uvelisa unyango abadala kunye nabantwana. Kuyaphawuleka ukuba kukho kuwo, ezizodwa zentliziyo yabantwana. izixhobo Modern isetyenziswa kunyango kwizigulane kunye noxilongo. mayixhotyiswe yesebe "Cardiology" kwakhona ezahlukeneyo eziphambili. Uxilongo yenziwa ngabasebenzi abaqeqeshiweyo. Unyango babe amayeza kunye instrumentally. Emva alulame, izigulane banikwa sicatshulwa yabo yesiqhelo. Cardiology eMoscow sise kwelona nqanaba liphezulu, ngoko awunaku kwazi ukoyika ngenxa yempilo yabo.

Iindleko zonyango kumbindi zentliziyo

Kuxhomekeka isifo indlela ebalulekileyo, amaxabiso zinokwahluka. Ukuba isigulane uhamba phantsi quota, yena uyakwazi ukubala le nkonzo simahla kuyo nayiphi inkalo iyeza: utyando, nezifo zentliziyo. kulo mzekelo, amaxabiso akusayi kufuneka ukuba sikhathazeke ukuba kuluncedo kakhulu kwaye ngexesha elinye ngokuthembekileyo.
