Kudzokorora monomorphic ventricular tachycardia (RMVT) rudzi rusina kujairika rwetricycarac tacycardia inowanzoitika kune vechidiki vane mwoyo yakafanana. Izvi zvakasiyana zvakasiyana nemhando inowanzoitwa ventricular tachycardia, iyo inonyanya kuonekwa kune vakwegura vane chirwere chegoni kana chirwere chemoyo .
Zviratidzo zve RMVT
RMVT kazhinji inobereka kakawanda, kwenguva pfupi, isina kusimbiswa "bursts" ye ventricular tachycardia, kunyange iyo yakajairikawo nevanhu vane chirwere ichi kuti vave nenguva yakareba episodes /
Zviratidzo zvinowanzoitika zvinokonzerwa neRMVT zviratidzo uye chirwere . Kunyanya kazhinji, syncope (kurasikirwa kwekuziva) kunogonawo kuitika. Nenzira yakanaka, njodzi yekusungwa kwemwoyo uye kufa kamwe kamwe ne RMVT kunoratidzika kunge yakaderera.
I-tricycardia ye ventricular inosanganisira RMVT inogona kukonzerwa nemamiriro ezvinhu umo adrenalin mazinga akakwirira. Nokudaro, vanhu vane RMVT vanogona kunge vane zviratidzo nemishonga (kunyanya, panguva yekudziya-nguva pakarepo mushure mekuita basa), kana panguva dzekurwadziwa mupfungwa. Ichokwadi, kuongororwa kwepfungwa - izvo zvinowanzotora urongwa hwemagirthmia - inzira inobvuma yekuongorora RMVT.
Ndiani Anowana RMVT?
RMVT inowanikwa inenge iri pasi pevanhu vanopfuura makore makumi mana kana makumi mashanu emakore, uye inoratidzika kunge yakakurumbira kune vanotambira. Dzimwe nyanzvi dzakafungidzira kuti vazhinji vasiri vatambi vanoberekwa nehuwandu hweM RMVT havangambotauri hurefu hwehutano hwepamweya hunowanzodiwa kuti utange aya magarthmia.
Kunyange zvazvo chinokonzera chikonzero chechiini chinoratidzika, izvi hazvina kuratidzwa.
Kurapa RMVT
Kurapa kwaM RMVT kunogona kuitwa kana kuchirapa kurapa kana nechirwere chekubatsira . Mishonga inogadziriswa inongowanikwa chete haisi yakakodzera muRMVT, sezvo njodzi yekufa kamwe kamwe inenge yakaderera.
Nenzira yakanaka, RMVT inogona kutaridzwa ne calcium blocker (verapamil) kana ne beta blockers (yakadai sepropranolol) - zvinodhaka zvinowanzobereka zvishoma zvishoma.
Kana mishonga iyi isingabhadhara zvakakwana zve ventricular tachycardia, kushandiswa kwemishonga inorwisa yakawanda inogona kurangarirwa, kunyange zvazvo mishonga iyi inowanzokonzera zvimwe zvinodhaka.
Mune varwere vakawanda vane RMVT, tachycardia ye ventricular inotangira munzvimbo inowanikwa munzvimbo yepamusoro ye ventricle yakarurama, iri pasi pevhavha yepulmonic. Mune varwere vashomanana vane RMVT, urramiti inouya kubva panzvimbo yakafanana nechokupedzisira ye ventricle - kureva, iri pasi pevhiriji ye aortic.
Chero zvazvingaitika, chokwadi chekuti urhythmia inobva kune imwe nzvimbo inoita kuti RMVT ishandiswe pakurapa. Kubudirira kubvumira kweMMVT kunogona kuwanikwa mune vanopfuura 90% varwere vane chirwere ichi.
Zvichipa izvi zvinosarudzwa, mamwe nyanzvi anotanga kuedza kurapa murwere ane RMVT achishandisa verapamil uye / kana beta blocker. Kana izvozvo zvisingabudiriri, chirongwa chekubvisa chinowanzoonekwa sechinhu chinotevera. Imwe nzira kana imwe, neine hutano hwakanaka iyo arrhythmias inosangana neRMVT inogona kutariswa kana kubviswa.
Shoko Rinobva
RMVT inorudzi rwetricycardia inonzi ventricular inowanikwa mune vamwe vane utano hwakanaka - zvikurukuru mumitambo.
Kunyange zvazvo njodzi yekufa kubva kuRMVT inoratidzika kunge yakadzika, iyi arrhythmia inogona kuvhiringidza muupenyu hwomunhu. Nenzira yakanaka, nerapa yakakodzera inogona kudzorwa kana kubviswa.
