Vamwe varwere vane kukanganisa kwemwoyo vanogona kuona kuwedzerwa kunoshamisa kwezviratidzo, vashoma vashanyi, uye nengozi shoma yekufa nerudzi rwekamwe pacemaker inonzi cardiac resynchronization therapy (CRT). Kana iwe uine chirwere chekushushikana kwemoyo, iwe unofanirwa kutaura nachiremba wako pamusoro pekugona kushandisa CRT.
Maitiro eCRT Anoshanda sei
CRT inoshandisa moyo wekombiki yekugadzirisa hutachiona kuti iongorore zvakare chiito chekodzero dzakasara uye dzakasara dzemakemikari muvasarudzwa vakasarudzwa vane mwoyo kusakonzerwa nekuda kwechirwere chemoyo .
Anenge munhu mumwe chete muvanhu vatatu vane urombo hwemwoyo ane chisingaoneki mumhepo yemagetsi yekuitisa system inonzi kuseri bundle branch block (LBBB) (kana kuti kusiyana kweLBBB inozivikanwa se "intraventricular conduction delayed"). Muvanhu ava, kushambadzira kwemaitiro kunokonzera kodzero uye kubva pamakwikwi ekubhururuka kuti arove kunze kwechibvumirano.Kumwe mamwe mazwi, panzvimbo yekurova panguva imwe chete iyo mhepo mbiri dzinobhururuka dzichirova zvishoma kubva muchikamu, imwe pashure peimwe.Iyo asynchrony inoderedza zvakanyanya kushanda kwemwoyo kune varwere vane mwoyo kusakundikana, uye inoita kuti zviratidzo zvemoyo kukundikana zvakanyanya.
CRT inoshandisa pacemaker inoyevedza iyo inogona kuenderera mberi mavariro maviri ari oga. Izvi zvakasiyana nemagadzirirwo anokonzera mhepo, iyo inofambisa chete ventricle yakarurama.
Nokukodzera nguva yekufamba kwayo kwemaviri emhepo, CRT inokwanisa kukonzerazve kurohwa kwavo kuitira kuti mhepo inobhururuka ichibvumirana panguva imwe chete panzvimbo yekuita sequentially.
Apo basa remakumbo maviri aya akabatanidzwa nenzira iyi, hutano hwemwoyo hunowedzera, uye huwandu hwebasa hunotora kuti mwoyo kupompa ropa yakaderedzwa.
Kubudirira kweRCT
Mamiriyoni emakiriniki akaedza kuongorora kubudirira uye kuchengetedzwa kweRTT kune varwere vane mwoyo kusakatika uye bundle branch block.
Meta-kutarisa kutarisa 14 yematambudziko aya akanyoresa 4420 varwere vane mwoyo usina kukwana vakagumisa kuti, mumakirani akasarudzwa zvakakodzera, CRT yakavimbika inogadzirisa zviratidzo uye simba rekushanda, inoderedza chiyero chezvipatara, uye inoderedza kufa.
Zvidzidzo zvakare zvakaratidza kuti CRT inogona kuvandudza zvose maitiro uye kushanda kwemoyo, zvichida kuderedza ukuru hweiyo yakasara yakasara, iyo inovandudza chikamu chekusiya ventricular ejection fraction .
Matambudziko eC CRT
CRT is pacemaker, saka inotakura mungozi imwechete yezvinetso zvaungazoona nemumwe mupiemaker, kusanganisira dambudziko duku rekutapukirwa, kukanganisa kumwoyo kana mitsipa yeropa, uye kubuda ropa. Mukuwedzera, dambudziko rinowanzobatanidzwa mukuisa mutungamiri wekufambisa unokwanisa kugadzirisa kuruboshwe. Munenge mune mumwe muvatachiri makumi maviri, kusara kwevashandi kunokonzerwa nekugadzikana hakugoni kuitwa uye CRT haigone kushandiswa.
Ndeapi Avo Vasina Mwoyo Vanokundikana Kunofungidzirwa KuRCT?
Nhungamiro yakarongeka inokurudzira kuti CRT inofungidzirwa kune varwere vane kushungurudzika kwemoyo kunounza zviratidzo zvikuru, vane rutivi rwokunze rwe ventricular ejection ye 0.35 kana pasi, uye yakasara bundle branch block.
Zvinonzwisisika, varwere vakawanda vanoona izvi zvigadziriswa zveCRT vachasanganawo nemiganho yeplanting defibrillator ( ICD ).
Saka rudzi rwakanyanya kupfuura rwechirongwa che CRT chinoshandiswa mumishonga yemakiriniki inobatanidza kanda ICD-CRT.
Shoko Rinobva
Kana iwe uine kukanganisa kwemwoyo izvo zvinokanganisa kukwanisa kwako kuita zvakanaka, uye iwe uri kutotambira kurapwa kwechirwere kune utsinye, iwe unofanirwa kurukura pamusoro pekugona kwe CRT nechiremba wako. Chiremba wako achakubatsira kuti uone kana iwe uri mukana wakanaka kune iyi yehutano uye kana CRT yakakunakira iwe.
