Supraventricular tachycardia, kapena SVT, ndi banja la maganizo a mtima omwe amachititsa kuti mtima ufulumire mofulumira. SVTs zimachokera ku atria ( zipinda zapamwamba za mtima ). Dzina lachikulire la SVT, limene inu mungamvepo nthawi zina, ndi paroxysmal atrial tachycardia (PAT).
Zizindikiro za SVT
Kawirikawiri, SVT imapezeka m'mabuku ovuta, omwe nthawi zambiri amayamba mwadzidzidzi ndikuima mofulumira.
Kotero zizindikiro za SVT zimawonekera kuti siziwonekera ndipo zimatha mwamsanga. Kutalika kwa zigawo izi kungakhale kuchokera kwa masekondi pang'ono mpaka maola angapo.
Pa nthawi ya SVT, kuthamanga kwa mtima kuli osachepera 100 pamphindi koma nthawi zambiri amakhala pafupi ndi 150 kugunda pa mphindi. Kwa anthu ena, kuthamanga kwa mtima kumakhala kofulumira koposa, nthawi zina kupweteka kwa 200 pa mphindi. SVT nthawi zambiri imapereka maitamini - kumverera kokhala ndi mtima wakuwonjezereka, kapena mtima wa masewera - zomwe zingakhale zoopsa kwambiri. Kuonjezera apo, munthu amatha kukhala ndi mutu wautali ndi chizungulire , zofooka, kutopa kapena dyspnea (kupuma pang'ono). Izi zikutanthauza kuti SVT ikhoza kukhala yokhumudwitsa kwambiri, ndipo ngati imachitika nthawi zambiri, SVT ikhoza kukhala yosokoneza kwambiri moyo wanu. Mwamwayi, SVT sichitha kuika moyo pachiswe.
Nchiyani Chimachititsa SVT?
Nthawi zambiri, SVT imapezeka mwa anthu omwe amabadwa ndi kugwirizana kwa magetsi kosaneneka mu mtima .
Nthawi zina, mauthenga enawa amatha kuwononga mwadzidzidzi kayendedwe ka magetsi mkati mwa mtima ndikukhazikitsa magetsi atsopano omwe amapanga arrhythmia.
Kwa anthu ena, zigawo za SVT zingayambitsidwe ndi zochita zolimbitsa thupi, nkhawa, m'mimba zizindikiro (monga kunyoza, kusanza kapena kuvomereza) kapena mankhwala.
Koma mwa anthu ambiri, SVT ikuwoneka kuti ikuchitika popanda chifukwa china.
Matenda ena azachipatala amawoneka akuchititsa SVT, makamaka matenda a mapapo ndi hyperthyroidism . SVT yowonongeka ndi matenda oterowo nthawi zambiri amasiyana kwambiri ndi SVT yowonjezera, chifukwa imakhala yochuluka kwambiri. Kuchiza mokwanira kawirikawiri kumafuna molimba mtima kuchiza vuto lalikulu lachipatala.
Kodi Mitundu ya SVT ndi Yotani?
SVT kwenikweni ndi banja la arrhythmias, ndipo mkati mwa banja lino, pali mitundu yambiri. Zizindikiro za mitundu yonseyi ya SVT ndi zofanana. Ngakhale njira zosiyanasiyana zothandizira ndizofanana, mankhwala "opambana" amatha kusintha, malingana ndi mtunduwo.
Kotero ngati muli ndi SVT, mungafunse dokotala wanu za mtundu womwe muli nawo, kotero mukhoza kuphunzira zambiri za izo.
Kodi SVT Yachita Zotani?
Masewera olimbitsa thupi a SVT nthawizonse amaima pokhapokha mphindi zingapo kapena maola angapo. Komabe, anthu ambiri adaphunzira kuimitsa masewera awo pochita chinachake kuti awonjezere mau a vagus nerve . Njira yosavuta yowonjezeramo kugonana ndi kuchita Valsalva . Njira yosavuta ndiyambitsa kuyendetsa bwino mwa kumiza nkhope yanu m'madzi a ayezi kwa masekondi angapo.
Ngati SVT yanu isayime mkati mwa mphindi 15 mpaka 30, kapena ngati zizindikiro zanu zili zovuta, muyenera kupita ku chipinda chodzidzimutsa. Dokotala akhoza pafupifupi nthawizonse kuimitsa chiwonetsero cha SVT mkati mwa masekondi powapatsa mlingo wa adenosine kapena Kalan (verapamil) .
Mwinanso mutha kulingalira za chithandizo chamankhwala chotheka kuti muteteze SVT kawirikawiri. Ndikofunika kukumbukira kuti SVT ndi yosavuta kwenikweni (koma "kupanga" chizindikiro). Izi zikutanthauza kuti pali njira zambiri zothandizira mankhwala.
Mwachitsanzo, anthu ambiri omwe ali ndi zigawo zochepa zokha komanso zochepa zochepa za SVT amasankha popanda mankhwala enaake; Iwo amangochita zinthu ndi zigawo zawo pamene zikuchitika.
Nthawi zambiri, SVT ikhoza kuchiritsidwa kamodzi ndi njira yowonjezera . Ma SVTs ambiri amayamba ndi njira zamagetsi zowonjezera, ndipo kawirikawiri, njira zowonjezereka zikhoza kukhala zovomerezeka mwapafupi ndi mapu a magetsi pamaphunziro a electrophysiology ndikuphatikizidwa. Njira yowonjezera ikatha, SVT sayenera kubwerera.
Mankhwala osokoneza bongo angagwiritsidwe ntchito pofuna kuyesetsa kupewa SVT, koma popeza mankhwalawa nthawi zambiri amagwira ntchito bwino, ndipo ambiri amakhala ndi zotsatira zovuta kwambiri, madokotala ambiri amakayikira kupereka mankhwala osokoneza bongo achilendo kuti athetse SVT, yomwe kachiwiri ndi benign arrhythmia yomwe ikhoza kufika pokhapokha. Komabe, mwa anthu ena, mlingo umodzi wa mankhwala osokoneza bongo, omwe watengedwa kumayambiriro kwa SVT, ungathandize kuthetsa mwatsatanetsatane mwatsatanetsatane.
Mawu Ochokera
SVT, ngakhale kawirikawiri imawopsyeza moyo, ingayambitse zizindikiro zazikulu ndipo ingasokoneze moyo wamba. Mwamwayi, pafupi mitundu yonse ya SVT ikhoza kuchiritsidwa bwino ndi kutetezedwa.
Ngati muli ndi SVT, kupambana kwanu ndikulankhula ndi electrophysiologist wa mtima (katswiri wamaganizo amene amadziwika ndi mavuto a mtima wamtima), ndani angakambirane nanu ndi ubwino wa njira zonse zothandizira kuti mukhale ndi mtundu wina wa SVT.
