Ventricular tachycardia iyo inomira pachayo mukati memaminitsi makumi matatu inonzi haisi yakasimudzirwa ventricular tachycardia (NSVT). Sezvo ventricular tachycardia inogona kunge inogona kuva nengozi yemaridythmia , iyo inoramba yakanyanya kuipa iyo inowanzova. Saka NSVT haina kunyanya kutyisa kupfuura ventricular tachycardia inopfuurira kwenguva refu. Kunyange zvakadaro, inogona kukonzera zviratidzo zvinokosha, uye zvinogona kuratidza kuwedzera kwengozi yemwoyo.
Overview
Tsanangudzo yakagadziriswa ye NSVT ndeye chiitiko che ventricular tachycardia ine kutengesa kwemwoyo kweanenge makumi mapfumbamwe makumi maviri neminomwe paminiti, inogara kwenguva refu katatu uye ichipfuurira pasi pemaminitsi makumi matatu.
Kazhinji kazhinji, NSVT zvimwe haibvumiri zviratidzo zvachose, kana kuti zvinogona kukonzera kupera . Dzimwe nguva, kunyange zvakadaro, NSVT inogona kuita kuti munhu ave nomusoro, chizivo , kana, kazhinji kazhinji, syncope (kurasikirwa kwekuziva).
Nemhaka yokuti NSVT haigoni kubudisa zviratidzo zvinotyisa, inowanzowanikwa muchiitiko, apo ichinyora electrocardiogram (ECG) kana mune imwe imwe nzira yekucherechedza mwoyo.
Nei Tichifanira Kukosha?
Kune zvikonzero zvitatu zveSVT zvinokosha. Chokutanga, iyo NSVT pachayo inogona kuunza zviratidzo zvinotambudza. Chechipiri, inogona kuratidza kuvapo kwepakutanga isingazivikanwi nehosha yepfungwa. Pakupedzisira, kuvapo kweSVV kunogona kuratidza kusagadzikana kwemagetsi kunotyisa kuwedzera kuipa, zvichida kutungamirira kune zvirongwa zvakanyanya kuipa zvakadai se ventricular fibrillation .
Kuziva
Kana iwe ukaonekwa kuti une NSVT, zvakanyanya kukosha kuti chiremba wako aongorore mwoyo kuti atsvake chirwere chepfungwa chepfungwa.
Mhando dzechirwere chepfungwa chinowanzobatanidza ne NSVT chirwere chechirwere chirwere (CAD) nekushaya mwoyo kunokonzerwa nekuderedza mwoyo. NSVT inowanikwawo ne hypertrophic cardiomyopathy uye nemwoyo yevhavha yezvirwere (zvikurukuru aortic stenosis uye mitral kudzokera ).
Zvizhinji zvezviitiko izvi zvinogona kutarisirwa kunze kwechirongwa chekodzero, asi kuongororwa kwetramum thallium kunogona kubatsirawo kana iwe uine mungozi yeCAD.
Dzimwe nguva, NSVT inokonzerwa nemamiriro emwoyo asingabatanidzwi nehutano hwepfungwa yemwoyo (ndiko kuti, chirwere chemwoyo chisingashandisi mafungiro emoyo). Nyaya yakawanda yezviitiko izvi inodzokorora monomorphic ventricular tachycardia (RMVT) . RMVT inowanzosangana nehutano hwemhepo inosanganisira iyo yemhepo yemagetsi, iyo inobereka kusarudzwa kwemaitiro kunowanikwa ne echocardiogram. Matambudziko akadai anoita kuti NSVT inowanzoongororwa apo chiremba anocherechedza zviitiko zvakasiyana zverhythmia pane ECG.
Kurapa
Muzviitiko zvakawanda, NSVT inonyanya kukosha sechiratidzo chepfungwa yepfungwa inogona kuvapo. Kana chirwere chemoyo chinowanikwa, chirwere chinofanira kutarirwa kune icho. Kana pasina chirwere chepfungwa chinowanikwa, kazhinji, iyo NSVT haina kuwedzera zvishoma nezvishoma ngozi yekumanikidzwa kwemoyo, uye kubva pakufungisisa kwechiremba, inowanzoitika kuti hapana kurapwa kunokosha.
Kwete kazhinji, chirwere chemwoyo chinokonzera pachako chinokonzera ngozi yakawanda yekufa kamwe kamwe kubva pamwoyo arrhythmias.
Izvi zvinonyanya kuitika kune CAD uye mwoyo kusakona. Mune mamiriro ezvinhu aya, njodzi yekumusungwa kwemoyo inobatana zvikuru kune kuruboshwe rwe ventricular fraction ejection kupfuura iyo kuvapo kana kusavapo kwe NSVT. Kuti kuderedze njodzi iyo, kana chikamu chejekisi chakanyanya kuderedzwa, chinoshandiswa chinogadziriswa chinogadziriswa chinofanira kunyatsoongororwa.
Muvanhu vane hypertrophic cardiomyopathy, kuvapo kweSVV kunoratidza njodzi yakakosha yekufa kamwe kamwe. Saka mune vanhu ava vane NSVT vaizoita kuti chirwere chegadzidza chigare chichienderera mberi kune chinangwa chekugadzirisa zvinokonzerwa nemhepo, kunyanya kana pane nhoroondo yekufa kamwe kamwe kubva ku hypertrophic cardiomyopathy mumhuri.
Kuva neVVV haina kuchinja kufungidzira kwechirwere chepfungwa chinonzi valvular, kusanganisira mitral valve prolapse , uye mumamiriro aya haafaniri kuva chinhu chinoita pakuita zvisarudzo zveutano.
Vechiduku vane zvizhinji zveSVV uye pasina chirwere chemwoyo chinokonzerwa nehutano chinofanira kutumidzwa kune mwoyo wekodhiphysiologist (mwoyo rhythm specialist) kuti uongororwe RMVT nezvimwe zvepabonde zvinogona kuita izvi. Aya maitiro e arrhythmias anowanzobatwa nekurapa kwekubvisa .
Mishonga
Kana zvaive nyore uye / kana kuti zvakachengeteka kubvisa NSVT nemishonga inodhaka, izvi hazvizove mubvunzo wakaoma. Zvinosuruvarisa, mishonga inopesana nemishonga inogona kushandiswa kubata chirwere cheSVV inowanzosava yakakosha uye inowanzoita kuti zvive nemigumisiro yakaipa kwazvo.
Kana chirwere chinodhaka chinoshandiswa, vanachiremba vanozotanga nekushandisa beta blockers , uye ipapo calcium channel blockers , sezvo mishonga iyi inogona nguva nenguva kuderedza zviratidzo, uye yakachengeteka. Zvisinei, kana kunyanya kushandisa zvinodhaka zvinenge zvichirangarirwa, kushandiswa kwavo kunofanira kunge nguva dzose kutungamirirwa ne-electrophysiologist yemwoyo.
Chinonyanya kukosha ndechekuti kukosha kweSVT hakuwanzoiti nezveSVV pachayo. Pane kudaro, kazhinji kacho pamusoro pekuti iyo NSVT inogona kuva chikonzero kune chinetso chemwoyo chinoda kuongororwa uye kuporerwa.
