Chimene muyenera kudziwa ponena za mtundu wamba wa SVT
Anthu omwe amavutika ndi matenda a tachycardia (masewera olimbitsa mtima), nthawi zambiri amakhala ndi mitundu yambiri ya tachycardia (SVT) . Liwu lakuti "SVT" limaphatikizapo mitundu yambiri yamaganizo ya mtima yomwe imayambira ndikuyimira mwadzidzidzi, yomwe nthawi zonse imakhala yopanda moyo, koma izi zingasokoneze kwambiri moyo wanu.
Atrioventricular reentrant reachrant tachycardia (AVRT) ndi mtundu wachiwiri wa SVT, wowerengera pafupifupi 30% mwa SVTs onse.
Kodi AVRT ndi chiyani?
AVRT ndi mtundu wa reentrant tachycardia . Monga momwe zilili ndi ma SVTs onse, anthu omwe ali ndi AVRT amabadwa ndi kugwirizana kosagwirizana kwa magetsi mu mtima. Mu AVRT, mgwirizano wowonjezera, womwe umatchedwa "njira yowonjezeramo," umapanga mgwirizano wagetsi pakati pa a atria (zipinda zapamwamba za mtima), ndi chimodzi mwa zinyumba (m'makilomita apansi a mtima).
Kawirikawiri, kugwirizana kokha kwa magetsi pakati pa atria ndi ventricles ndi njira yachibadwa yopangira mtima, yomwe ili ndi kachidindo ka AV ndi mtolo Wake.
Kotero, mwa anthu omwe ali ndi AVRT, njira yopezeramo njira imapereka mgwirizano watsopano wa magetsi pakati pa atria ndi zinyama. Kulumikizana kwachiwiriku kumapanga dera lotha kuyendetsa tachycardia.
Kodi AVRT Zimagwira Ntchito Bwanji?
Kwa munthu amene ali ndi njira yowonjezeramo, chigawo cha AVRT chikhoza kuyambidwa ndi kupweteka kwa mtima msanga, mwina kutsekedwa kwa nthawi yayitali (PAC) kapena kuvomereza kwa msanga (PVC) .
Kumenyedwa msanga msanga, ngati kumachitika panthaŵi yoyenera, kungayambitse kugwedeza (kapena kubwezeretsa) magetsi.
Maganizo amenewa amayenda pansi poyendetsa kayendedwe kake, kenako amayendanso njira yowonjezeretsa ku atria (ndiko kuti, "obwerera"), kenako amayendayenda ndikuyambiranso kuyenda, ndi zina zotero.
Motero, kumenyana kosafika msanga kumayambitsa tiachcardiadia mwadzidzidzi.
Zizindikiro za AVRT ndizofanana ndi SVT. Kawirikawiri zimaphatikizapo mapiritsi , kumutu , ndi chizungulire . Ma Episodes nthawi zambiri amatha mphindi zingapo mpaka maola angapo.
Kodi AVRT Ikani Kutani?
AVRT ikhoza kuyimitsidwa ndi PAC, PVC, kapena kungochepetsetsa kupangitsa magetsi kupyolera mu vesi la AV. Zonse mwa zochitikazi zingathe kusokoneza chifuwa cha reentrant.
Mfundo yakuti kuchepetseratu kupititsa patsogolo kachilombo ka HIV kungaimitse AVRT kumapatsa munthu mwayi wokhala ndi mwayi woterewu. Mpata uwu umapindula ndi mfundo yakuti kachilombo ka AV kamaperekedwa kwambiri ndi vagus nerve . Choncho, anthu omwe ali ndi AVRT amatha kuimitsa chiwombankhanga mwachitapo kanthu kuti adziwe momwe amachitira nkhanza zawo. Izi zingatheke, mwachitsanzo, pogwiritsa ntchito njira ya Valsalva , kapena kumiza nkhope yanu mu madzi a ayezi kwa masekondi pang'ono. (Kuyenda kwa Valsalva ndikofulumira, kosavuta, komanso kosasangalatsa kusiyana ndi maonekedwe a madzi oundana.)
AVRT ndi Wolff-Parkinson-White Syndrome
Kwa anthu ena omwe ali ndi AVRT, njira yowonjezeramo imatha kuyendetsa magetsi mu njira iliyonse (kutanthauza, kuchokera pa atrium mpaka ventricle monga momwe tafotokozera kale, kapena kuchokera ku ventricle mpaka ku atrium). Kwa anthu ena, njira yopezeramo njira ingangoyendetsa magetsi pambali imodzi kapena ina.
Kusiyana kumeneku kumakhala kofunikira. Kwa anthu ambiri omwe ali ndi AVRT, malingaliro amatha kudutsa njira yopezera njira kuchokera ku ventricle kupita ku atrium.
Pamene zovuta zimatha kuwoloka kumbali inayo - kuchokera ku atrium kupita ku ventricle - Matenda a Wolff-Parkinson-White (WPW) akupezeka.
WPW imayanjanitsidwa ndi mavuto a zachipatala omwe amapitirira kuposa "chilungamo" AVRT, ndipo kawirikawiri amafunika kuchitiridwa nkhanza kwambiri.
Kuchiza AVRT
Ngati WPW salipo ndipo zizindikiro za AVRT ndizosawerengeka ndipo zimaima mosavuta (nenani, pochita maulendo a Valsavla), nthawi zambiri palibe chithandizo chofunikira kuposa kuphunzira zomwe mungachite pamene chochitika chikuchitika. Komabe, ngati muli ndi WPW, mafupipafupi a SVT, makamaka zizindikiro zoopsa m'zaka zapakati, kapena zovuta kutseka zizindikiro zikachitika, ndiye kuti mankhwalawa ayenera kugwiritsidwa ntchito kwambiri.
Mankhwala osokoneza bongo amathandiza nthawi zambiri popewera zigawo za AVRT. Komabe, mwa anthu ambiri omwe ali ndi AVRT, mankhwala ochepetsa ablation amatha kuchotseratu njira yowonjezeramo, ndipo amalepheretsanso magawo ena onse. Ndi njira zamakono, njira zowonongeka zowonjezera zingathe kuchitidwa bwino komanso mosamala nthawi zambiri.
Mawu Ochokera
Atrioventricular reentrant tachycardia (AVRT) ndi mitundu yosiyanasiyana ya SVT. Ngakhale kuti nthawi zambiri zimakhala ndi zizindikiro zazikulu ndipo zingasokoneze moyo, AVRT lero ndi yotheka kwambiri.
