Kubwereza mobwerezabwereza monomorphic ventricular tachycardia (RMVT) ndi mtundu wosadziwika wa tachycardia wa ventricular umene umakhalapo mwa achinyamata omwe mitima yawo ili yachilendo. Izi zimasiyana kwambiri ndi mtundu wa tricycardia, umene umapezeka nthawi zambiri anthu okalamba omwe ali ndi matenda a mitsempha kapena matenda a mtima .
Zizindikiro za RMVT
RMVT kawirikawiri imapanga kawirikawiri, mwachifupi, osagwira ntchito "zotupa" za ventricular tachycardia, ngakhale zili zofala kuti anthu omwe ali ndi vutoli amakhala ndi nthawi zambiri /
Zizindikiro zowonjezereka zomwe zimayambitsidwa ndi RMVT ndizozikhalitsa ndi chizungulire . Nthawi zambiri, syncope (kuperewera kwa chidziwitso) ikhozanso kuchitika. Mwamwayi, chiopsezo cha kumangidwa kwa mtima ndi imfa mwadzidzidzi ndi RMVT zikuoneka kuti ndi otsika kwambiri.
Tachycardia yotchedwa ventricular yokhudzana ndi RMVT ingayambitsidwe ndi mikhalidwe yomwe mazinga adrenalin akukwera. Choncho, anthu omwe ali ndi RMVT amatha kukhala ndi zizindikilo pogwiritsa ntchito masewero olimbitsa thupi (makamaka nthawi yotentha nthawi yomweyo mutatha kuchita masewera olimbitsa thupi), kapena nthawi yachisoni. Ndipotu, kuyezetsa kupanikizika - zomwe nthawi zambiri zimabweretsa arrhythmia - ndi njira yodalirika yodziwira RMVT.
Ndani Amalandira RMVT?
RMVT imawoneka pafupifupi kwa anthu osakwana zaka 40 kapena 45, ndipo zikuwoneka kuti ndi otchuka kwambiri kwa othamanga. Akatswiri ena amalingalira kuti ambiri omwe si othamanga omwe amabadwa ndi mphamvu ya RMVT samangobweretsa mavuto apamwamba omwe nthawi zina amafunika kuti ayambitse mayendedwewa.
Ngakhale kuti zikuoneka kuti chibadwa chapachiyambi chimayambira, izi sizinatsimikizidwe.
Kuchiza RMVT
Chithandizo cha RMVT chikhoza kuchitidwa mwina ndi mankhwala azachipatala kapena ndi mankhwala opatsirana . Zomwe zimayambitsa matendawa zimakhala zosafunika kwenikweni ku RMVT, chifukwa chiopsezo cha imfa mwadzidzidzi ndi chochepa.
Mwamwayi, RMVT imatha kulamulidwa ndi calcium blocker (verapamil) kapena ndi beta blockers (monga propranolol) - mankhwala omwe amakhala ndi zotsatira zochepa chabe.
Ngati mankhwalawa samapereka mankhwala okwanira a tricycardia, kugwiritsidwa ntchito kwa mankhwala amphamvu olimbitsa thupi kungaganizidwe , ngakhale mankhwalawa amachititsa kuti tizilombo toyambitsa matenda tizilombo toyambitsa matenda.
Kwa odwala ambiri omwe ali ndi RMVT, tachycardia ya ventricular imachokera kumalo omwe ali m'dera lakumtunda kwa ventricle yolondola, pamunsi pa valasi ya pulmonic. Kwa odwala ochepa amene ali ndi RMVT, arrhythmia imachokera kumalo omwewo kumbali ya kumanzere - yomwe ili pansi pa valve ya aortic.
Mulimonsemo, chifukwa chakuti chiyambi cha arthmia chimachokera ku malo ena amachititsa kuti RMVT ikhale ndi mankhwala othandiza. Kupititsa patsogolo ntchito ya RMVT kungapezeke mwa odwala oposa 90% omwe ali ndi vutoli.
Chifukwa cha mankhwalawa, akatswiri ambiri amayamba kuyesa wodwala ndi RMVT pogwiritsa ntchito verapamil ndi / kapena beta blocker. Ngati izo sizikuyenda bwino, mankhwala ochepetsa ablation amawonedwa kuti ndi sitepe yotsatira. Njira imodzi kapena ina, ndi chithandizo chamankhwala bwino arrhythmias yogwirizana ndi RMVT amatha kulamulidwa kapena kuthetsedwa.
Mawu Ochokera
RMVT ndi mtundu wina wa tachycardia wotchedwa ventricular omwe amawonedwa ndi achinyamata omwe ali ndi thanzi labwino - makamaka othamanga.
Ngakhale kuti chiopsezo cha imfa kuchokera ku RMVT chikuwonekera kukhala chochepa, izi zimakhala zosokoneza moyo wa munthu. Mwamwayi, ndi mankhwala oyenera akhoza kulamulidwa kapena kuchotsedwa.
