Sinius nodal reentrant tachycardia (inonziwo SNRT) ndeimwe yemagirthmias akabatanidzwa sepamusoro- soro tachycardia (SVT) , iyo inokurumidza mwoyo magythmias inotangira muatria yemwoyo. Sinus nodal reentrant tachycardia ndiyo inonzi rarest yeSVT.
Overview
Sinus nodal reentrant tachycardia is reachant tachycardia . Sezvakaitika nguva dzose ne reentrant tachycardias, sinus nodal reentrant tachycardia inoitika nekuti kune humwe humwe hutano hwemagetsi mukati memwoyo, huripo kubva pakuberekwa.
Mu sinus nodal reentrant tachycardia, humwe hutano huripo - uye zvechokwadi iyo yose yekare inotenderera inogadzira urhythmia - iri mukati mediki node ye sinus .
Zviratidzo
Zviratidzo zveSNRT zvakafanana nezviratidzo zvinowanzoonekwa nemhando ipi neipi yeSVT. Chiratidzo chinonyanya kukosha kupera , kunyange zvazvo vamwe vanhu vane chirongwa ichi vachizoonawo " mutsipa wakachena" rudzi rwechezzinesi .
Sezvakawanda neSVTs, zviratidzo zvinowanzotanga pakarepo uye pasina chero nyevero. Izvo zvinoperawo zvakaenzana kamwe-kamwe kazhinji mushure memaminetsi mashomanana kusvika maawa akawanda.
Nhamba ye sinus inowanikwa zvakakwana neve vagus nerve , saka vanhu vane sinus nodal reentrant tachycardia vanogona kumira matanho avo nekutora matanho ekuwedzera izwi revari vagar nerve yavo, sekuita basa reValsalva , kana kuisa chiso chavo mumvura yechando mashoma mashomanana.
Kusiyanisa Kubasa Risina Kukodzera Tachycardia
Sinus inappropriate tachycardia (IST) yakafanana nesinus nodal reentrant tachycardia sezvo zvose izvi izvi zvinokonzerwa node node.
Zvisinei, maitiro avo akasiyana zvikuru. Sinius nodal reentrant tachycardia is reachrant tachycardia, saka inotanga uye inomira pakarepo, sekutendeuka uye kurega kushandura chiedza; uye kana murwere asina chikamu chaiyo che tachycardia, moyo wake wekutengesa uye mwoyo rhythm unoramba wakakwana.
Kusiyana neizvi, IST ndiyo tachycardia inotsvaga . Nemhaka yeiyo, haisi kutanga nekumira zvishoma asi asi, inowedzera zvishoma nezvishoma uye inowedzera kuwedzera. Uyewo, kushaya mwoyo mukati mevanhu vazhinji vane IST kazhinji hazviiti zvachose zvachose "zvakajairika." Pane kudaro, kuwedzera kwemwoyo kunenge nguva dzose kunoramba kwakasimudzirwa, kunyange kana kusina zviratidzo.
Kurapa
Kana zvikamu zve tachycardia zvisingawanzozivikanwi, uye kunyanya kana zvikamu izvi zvingave nyore kumiswa nekuwedzera vagal tone, vanhu vane sinus nodal reentrant tachycardia vangave vasingadi chero kurapwa mune zvoutano zvachose-kunze kwekudzidza kuti vanoziva sei kuti arthmia iri kuitika, uye sei kuti iimise.
Kana pane kurapwa kwakanyanya kuchidiwa - zvichida nekuda kwezviitiko zvinowanzoitika kana kuti kuoma mukugumisa zvikamu - chirongwa chemishonga chinowanzobudirira. Kutora beta blocker kana calcium channel blockers kazhinji kunoderedza kukuruka kwezvikamu, uye / kana kuita kuti zvive nyore kumira.
Kana sinus nodal reentrant tachycardia inonyanya kunetseka uye isingatauri kune chirwere chiduku chisingaoneki, therapy inopera inowanzobudirira mukubvisa armimia zvachose.
Zvisinei, zvakaoma kubvisa nzira yakawanda yemagetsi mu node ye sinus kunze kwekukuvadzawo zvimwe zvakasara zve node ye sinus.
Nokudaro nzira yekubvisa ine ngozi yakajeka yakakura yekubudisa sinasi yakakura bradycardia , kusvika pakuti pacemaker inogara ichinyanya kudiwa.
Nokudaro, kuedza kutsvaga kurapwa kusina kukodzera kunofanira kuitwa nguva dzose tisati taongorora kubhadharwa kwepabonde ye sinus nodal reentrant tachycardia.
