Apo RBBB iri Dambudziko?
Chikamu chakanaka chebazi bhenzira isingaenzaniswi inowanikwa pa electrocardiogram (ECG) , iyo inoratidza kuti moyo wemagetsi wemagetsi haisi kugoverwa kazhinji kune dzimwe mhepo . Kunyanya, bhora rakanaka rebazi rinoreva kuti kushandiswa kwemagetsi kwekodzero yakakodzera iri kutambidzwa.
Chii Chinokonzera Munda Wakakodzera Webazi?
Matavi maviri ehomwe (kurudyi uye kuruboshwe) ndiyo nzira dzemagetsi dzinobvumira mafungiro emagetsi emagetsi kupararira nokukurumidza uye nenzira yakafanana kuburikidza nemakumbo maviri, kuitira kuti kurohwa kwemwoyo kwakanyatsogadziriswa.
Nebhokisi rakanaka rebazi, pane kuvhara zvishoma kana kwakakwana kwekushandiswa kwemagetsi kune ventricle yakarurama. Chikamu chemahombekiti chebazi rakanonoka kunonoka kushandiswa kwemagetsi kwe ventricle yakarurama. Pakupedzisira, ventricle yakarurama inokurudzirwa mushure mekusiyiwa kwebasirikiti inokurudzirwa, uye kukanganisa kwayo kunonoka.
Kusiyana nechokumucheche bundle branch block (umo kukurudzira kwebhokisi riri kuruboshwe kunonoka), zvakanaka bundle bazi rekutsva haritauri basa rose remoyo mukati chero ipi zvayo inogona kuenzaniswa. Saka zvakanaka bundle bazi rega pachavo rinowanzoonekwa senhengo yehutachiona iyo hairevi chero kurapa kwakananga.
Kunyange zvakadaro, chikwangwani chebazi chakanaka chichiri chiitiko chinokosha. Zvarinoreva zvisiri izvo munharaunda iyo inowanzobatanidzwa nechimwe chepfungwa chepfungwa kana yemapurmoni. Saka apo bhomba rakanaka rebazi rinowanikwa, chirongwa chekurapa chinowanzodiwa.
Kuongororwa Mubatanidzwa Wekona Bhuku
Chikamu chakanaka chebazi chinokonzera kuchinja kwemaitiro paEECG, saka vanachiremba vanogona kazhinji kugadzirisa chirwere ichi nekungoongorora electrocardiogram.
Muchikwata chebazi , chidimbu cheQRS-chikamu cheEECG iyo inomiririra kushandiswa kwemagetsi kuenderera mberi kune mhepo-mhepo-yakazara kupfuura yakasvibirira, sezvo inotora nguva yakareba kupfuura yakasarudzwa kuti chido chekugoverwa.
Muchikwata chakanaka chebazi, kune chimiro chechimiro ichi kupararira kunotora mitsara 12 (kana kuti "maonero") inopiwa neEECG yakazara. Saka, nekungocherechedza muenzaniso wekuwedzera kweKRS yakaoma, zvinowanzova nyore kuziva kuti kuvapo kwekodhi bundle branch block.
Sei Chikonzero Chakakoshesa Chikamu Chechivharo Chinokosha?
Nzvimbo yekodhi yakanaka yebazi inowedzera nezera. Iyo inowanikwa chete kazhinji pavechidiki, asi vanopfuura 11 muzana yevanhu vane makore makumi mapfumbamwe nemakore vane chikwereti chakanaka chebazi.
Nhengo yebazi yebazi yakawanda inowanzoonekwa, uye mishonga haina kunyanya kukosha, kudarika imwe yaro, yakasiya bundle branch block. Apo bongo rebazi rebazi rakanaka rinoonekwa, chinonyanya kukoshesa kufanirwa kuve kuita kuongororwa kutarisa chinangwa chechimiro kana chirume chemapurimari.
Kana pasina mamiriro ezvinhu akadaro anowanikwa, bhokisi rebazi rakakodzera rinogona kuonekwa sechinhu chakanaka (kwete kukuvadza).
Chikamu Chakarurama Chebazi Chekuvhara uye Mwoyo Wakadzikama uye Mwoyo Wakakomba
Iko bhomba rakanaka rebazi, sezvarinodzidzisa mukati memutsipa wekodzero yakakosha, haina kungofanana nechepamusoro pemhepo yevhu. Izvi zvinoita kuti bhanga rebazi rakanaka risvike pakuvhiringidzika uye kutambanudza chero nguva iyo inonzi right ventric inowanikwa pasi pekunetseka kwemhando ipi zvayo.
Saka, bhomba rebazi rakanaka rinowanzoitika kune chero mamiriro ezvinhu anokonzera ventricle yakarurama. Izvi zvinogona kusanganisira maronary artery disease (CAD) , myocarditis (kuvhuvhuta musimba wemwoyo), kuparara kwepatrial septal , ventricular septal defect, uye chirwere chemwoyo chinonzi valvular .
Uyezve, chikwangwani chebazi rebazi chinogonawo kuonekwa nemamiriro ezvinhu emapapu anokonzera kukwirira kusingaperi mumatambudziko mukati me ventricle yakarurama, kunyanya kupemha yeupemeniti . Pulmonary hypertension, uyewo, inogona kukonzerwa nehutano hwemapapu akasiyana-siyana emapapu, anosanganisira chirwere chisingaperi chisinganzwisisiki chepodemoni (COPD) uye kuvhiringidza kupona kwepabonde .
Kucherechedza, chikamu chakanaka chebazi chinowanikwa nechinangwa chero chipi zvacho chinomutsa zvinomanikidzwa mumakwikwi akanaka. Chinhu chakajairika chinoita izvi ndezvemaplmoni.
Somugumisiro, ani zvake anoonekwa kuti ane chikamu chakanaka chebazi rebazi rinofanira kurapwa kwechiremba inotarisa pane zviratidzo zvepfungwa yemwoyo kana mapapu. Bhokisi re x-ray uye echocardiogram kazhinji-inoshandiswa kushandiswa zvishandiso zvechinangwa ichi.
Nemhaka yokuti gorosi rakanaka rebazi rinotarisana nechinhu chipi nechipi chinogona kubudisa kunyange kushungurudzika kwakanyanya mu ventricle yakarurama, nguva inenge yakarurama yebato rebazi inowanikwa munenge ma5 kubva muzana yevarwere vane chirwere chemwoyo chinonzi catheterization . Iri bhizimisi rekodhi rebazi rechechi rinowanikwa nguva iyo catheter inovhiringidza bharle rebazi rakakodzera. Iyi nguva yakareba bundle bazi rinowanzogadzirisa nokukurumidza (mumaminitsi) kana katheta ichibviswa.
Zvisinei, kune vanhu vakatosiya bundle branch block, zvichikonzera kunyange iyi iri nguva yakatarwa bundle branch block ingangodaro inogadzira nguva yakakwana yemwoyo , uye mwoyo unogona kumisa kurova. Saka, kune vanhu vane chikamu chekupedzisira chebazi rebazi vanove nekodhi yekodhi catheterization, pane imwe nguva pacemaker inoshandiswa panguva ino, kuti ivimbise kuti mwoyo rhythm icharamba ichinyatsogadziriswa panguva yekudzidza.
Chikamu Chakarurama Chebazi Rekuvhara uye Kubudirira kweMoyobeat
Nekodzero kana kuruboshwe bundle branch block, moyo wemhepo mbiri dzinosimudzirwa dziri kukurudzirwa zvakaenzana (imwe pashure peimwe) pane imwechete imwe chete. Kurasikirwa uku kwekugadzirisana kwemazuva ose pakati pemakumbo maviri kunogona kuderedza kushanda kwekurova kwemoyo.
Zvisinei, kuderedzwa kwehutano hwemwoyo hazvina zvishoma uye hakuna zvakagadzirisa mubato rakanaka rebazi. Nokudaro, somuenzaniso, kushandiswa kwemwoyo wekubwinya kwechirwere (CRT) hakukurudzirwi kune vanhu vane bundle rakanaka rebazi, kunyange kana vane mwoyo yekukundikana .
Munda Wakarurama Webazi Unovhara Unoda Kuti Uve Nemapemaker?
Chikamu chakanaka chebazi, iro pacharo, haritomboregi kurapwa neine pacemaker inogara nokusingaperi. Zvisinei, mune vamwe vanhu bhomba rebazi rebazi rakadaro hazviitiki pacharo, asi pane rinomiririra kuratidzwa kumwe kwechinetso chinowanzoenderana nemhepo yemagetsi yekuita. Mumamiriro ezvinhu akadaro pacemaker inogona kudiwa kana pakupedzisira inoda kana chirwere chechi sinus syndrome kana kuti moyo block inofanira kukura.
Shoko Rinobva
Chikamu chakanaka chebazi rega pachako chigadzirisa chirwere chisingadi kurapwa. Zvisinei, chero ani anowanikwa kuti ave nawo anofanira kuva nekuongorora kuongorora kutonga kunze kwepfungwa yepfungwa kana mapapu. Kana kusina kuwanikwa, ipapo bhokisi rebazi rakakodzera rinogona kunyorwa sekutsvaga kusina kuitika, pasina kukosha kwehutano hunokosha.
