Paroxysmal supraventricular tachycardia (PSVT)

Paroxysmal supraventricular tachycardia (PSVT) ndi magawo othamanga kwamtima omwe amayamba mu gawo lina la mtima pamwamba pa ma ventricles. "Paroxysmal" amatanthauza nthawi.

Nthawi zambiri, zipinda zamtima (atria ndi ma ventricles) zimagwirizana m'njira yolumikizana.

• Zocheperako zimayambitsidwa ndi chizindikiro chamagetsi chomwe chimayambira mdera lamtima lotchedwa sinoatrial node (yotchedwanso sinus node kapena SA node).
• Chizindikirocho chimadutsa muzipinda zakumtunda (atria) ndikuwuza atria kuti agwirizane.
• Pambuyo pake, chizindikirocho chimatsikira pansi pamtima ndikuuza zipinda zapansi (ma ventricles) kuti zigwirizane.

Kuthamanga kwamtima kuchokera ku PSVT kumatha kuyamba ndi zochitika zomwe zimachitika m'malo amtima pamwamba pazipinda zotsika (ma ventricles).

Pali zifukwa zingapo za PSVT. Ikhoza kukula pamene mankhwala a mtima, digitalis, amakhala okwera kwambiri. Zitha kukhalanso ndi vuto lotchedwa Wolff-Parkinson-White syndrome, lomwe limakonda kuwonekera mwa achinyamata ndi makanda.

Zotsatira zotsatirazi zimawonjezera chiopsezo chanu ku PSVT:

• Kumwa mowa
• Ntchito ya caffeine
• Kugwiritsa ntchito mankhwala osokoneza bongo
• Kusuta

Zizindikiro nthawi zambiri zimayamba ndikuyimira mwadzidzidzi. Amatha kukhala kwa mphindi zochepa kapena maola angapo. Zizindikiro zimaphatikizapo:

• Nkhawa
• Kukhazikika pachifuwa
• Palpitations (kutengeka kwakumva kugunda kwa mtima), nthawi zambiri kumakhala kosafulumira kapena kuthamanga mwachangu (kuthamanga)
• Kutentha mwachangu
• Kupuma pang'ono

Zizindikiro zina zomwe zitha kuchitika ndi izi ndi izi:

• Chizungulire
• Kukomoka

Kuyezetsa thupi nthawi ya PSVT kukuwonetsa kugunda kwamtima mwachangu. Ikhozanso kuwonetsa zokopa zamphamvu m'khosi.

Kugunda kwa mtima kumatha kukhala kopitilira 100, komanso kuposa kugunda kwa 250 pamphindi (bpm). Kwa ana, kugunda kwa mtima kumakhala kokwera kwambiri. Pakhoza kukhala zizindikilo zosayenda bwino kwamagazi monga kupepuka mutu. Pakati pa zigawo za PSVT, kugunda kwa mtima kumakhala bwino (60 mpaka 100 bpm).

ECG panthawi yazizindikiro ikuwonetsa PSVT. Kafukufuku wamagetsi (EPS) angafunike kuti mupeze matenda olondola ndikupeza chithandizo chabwino kwambiri.

Chifukwa PSVT imabwera ndikudutsa, kuti iwuzindikire anthu angafunike kuvala chowunikira cha maola 24 a Holter. Kwa nthawi yayitali, tepi ina yazida zojambula zingagwiritsidwe ntchito.

PSVT yomwe imachitika kamodzi kokha sangafunikire chithandizo ngati mulibe zizindikiro kapena mavuto ena amtima.

Mutha kuyesa njira zotsatirazi kuti musokoneze kugunda kwamtima munthawi ya PSVT:

• Kuyendetsa kwa Valsalva. Kuti muchite izi, mumakhala ndi mpweya komanso kupsyinjika, ngati kuti mukuyesera kuyenda.
• Kutsokomola mutakhala pansi ndi thupi lanu lakumtunda likuyang'ana patsogolo.
• Kuwaza madzi oundana pankhope panu

Muyenera kupewa kusuta, caffeine, mowa, komanso mankhwala osokoneza bongo.

Chithandizo chadzidzidzi chochepetsera kugunda kwa mtima kubwerera mwakale chimaphatikizapo:

• Kutaya mtima kwamagetsi, kugwiritsa ntchito magetsi
• Mankhwala kudzera mumtsempha

Chithandizo cha nthawi yayitali kwa anthu omwe amabwereza zigawo za PSVT, kapena omwe ali ndi matenda amtima, atha kukhala:

• Kuchotsa kwamtima, njira yomwe imagwiritsidwa ntchito kuwononga malo ang'onoang'ono mumtima mwanu omwe angayambitse kugunda kwamtima (pakadali pano chithandizo chamankhwala ambiri a PSVTs)
• Mankhwala a tsiku ndi tsiku oletsa magawo obwereza
• Opanga ma pacem kuti athetse kugunda kwamphamvu kwanthawi (nthawi zina atha kugwiritsidwa ntchito kwa ana omwe ali ndi PSVT omwe sanayankhe mankhwala aliwonse)
• Kuchita opaleshoni kuti musinthe njira zomwe zili mumtima mwanu zomwe zimatumiza zida zamagetsi (izi zitha kulimbikitsidwa nthawi zina kwa anthu omwe amafunikira kuchitidwa opaleshoni ina yamtima)

PSVT nthawi zambiri siyowopseza moyo. Ngati matenda ena amtima alipo, atha kubweretsa kusokonezeka kwa mtima kapena angina.

Imbani wothandizira zaumoyo wanu ngati:

• Mukumva kuti mtima wanu ukugunda mwachangu ndipo zisonyezo sizimatha zokha mumphindi zochepa.
• Muli ndi mbiri ya PSVT ndipo chochitika sichichokera pakuyendetsa kwa Valsalva kapena kutsokomola.
• Muli ndi zizindikiro zina ndi kugunda kwamtima mwachangu.
• Zizindikiro zimabwerera pafupipafupi.
• Zizindikiro zatsopano zimayamba.

Ndikofunikira kwambiri kulumikizana ndi omwe amakupatsani ngati muli ndi mavuto ena amtima.
