Xa iRBBB ingxaki?
I-block block yesigqeba esilungileyo yindlela yokungaqhelekanga ibonwa kwi- electrocardiogram (ECG) , ebonisa ukuba intliziyo yentshukumo yombane ayinasasazwa ngokuqhelekileyo kuwo onke ama -ventricles . Ngokukodwa, ibloko yesigqeba eselungileyo lithetha ukuba ukuvuselelwa kombane we-ventricle efanelekileyo kunqabile.
Yintoni eyenza iCandelo leSigqeba saseNkundleni iLungile?
Amasebe amabini amaninzi (ngakwesobunxele nakwesobunxele) yindlela yamandla eyenza ukuba umbane womoya ugxilise ngokukhawuleza ngokukhawuleza ngeendlela zombini, ukwenzela ukuba ukubetha kwentliziyo kulungelelaniswe kakuhle.
Ngomgca wesigqeba esisekunene, kukho ukukhutshwa okukodwa okanye okuphelileyo kwindlela yokusebenzisa umbane kwi-ventricle efanelekileyo. I-block block yesigqeba sokunene isalathisa ukusetyenziswa kombane kwe-ventricle efanelekileyo. Emva koko, i-ventricle efanelekileyo ivuselelwa emva kokuba i-ventricle ekhohlo ivuselelwe, kwaye ukukhawulwa kwayo kulibazisekile.
Ngokuphambene nesithintelo segatsha lesigxina (apho i-ventricle ekhohlo ikhunjulwa khona), i-block bundle block block ayiyikuyekethisa umsebenzi jikelele wentliziyo kunoma iyiphi nayiphi indlela enokulinganisa. Ngoko ibloko yesigqeba eselungileyo ngokwalo lisoloko lithathwa njengesimo esibuhlungu esingafunanga nonyango oluthile.
Nangona kunjalo, ibhloko yesigqeba esisekunene sisabalulekile ekufumaneni. Ukubaluleka kwayo kuxoxwa kwinto ehlala ihambelana nesimo esithile senhliziyo okanye i-pulmonary condition. Ngoko ke, xa i-block block yesigqeba esifanelekileyo ifunyaniswa, kuhlolwa rhoqo unyango.
Ukuchonga i-Right Bundle kwiBlue Block
Isibonda segatsha esisekunene senza ukuba utshintsho oluphawulekayo kwi-ECG, ngoko ke oogqirha banokukwazi ukuxilonga le meko ngokulula ngokuhlola i-electrocardiogram.
Kwi- block block yesigqeba , i-QRS isakhiwo-isahlulo se-ECG esimele umfutho wombane ohamba ngaphaya kwee-ventricle-ububanzi kunokoqhelekileyo, kuba kuthatha ixesha elide kunexesha eliqhelekileyo ukuba isisombululo sisasazwe.
Kwinqanaba legatsha elisekunene, kukho iphethini ephawulekayo le nto ithatha iinqununu ezili-12 (okanye "iimbono") ezibonelelwe yi-ECG. Ngoko, nje ngokuqwalasela umzekelo wokwandiswa kwe-QRS ezinzima, kudla ngokulula ukucacisa ubukho bebloko legatsha elifanelekileyo.
Kutheni i-Right Bundle Isigqeba seBlue Block?
Isiganeko segatsha lesigqeba esilungileyo sanda ngokukhula. Kubonakala kubunqabileyo kubantu abancinci, kodwa ngaphezulu kwama-11 ekhulwini abantu abaneminyaka engama-80 banesigqeba segatsha esifanelekileyo.
Isibonda segatsha sokunene siqhelekile, kwaye imithi ingabalulekanga kangako, kunokuba umlingani wayo, isithintelo segatsha esishiyelweyo. Xa kufunyenwe ibhloko yesigqeba esilungileyo, ukukhathazeka ngokuyinhloko kufuneka kuyenze uvavanyo lokukhangela isimo sengqondo somzimba okanye impompo.
Ukuba akukho nhlobo imeko ifunyenwe, ibhloko yesigqeba esilungileyo ngokubanzi linokuthi lithathwe njengobungozi (kungabonakali).
Isigqeba soLungileyo kwiBatsha leNgcini kunye neNtsholongwane yeNtliziyo kunye neeNtsholongwane
Isebe elungileyo lefestile, njengoko iikholeji ngaphakathi kwisistim ye-ventricle efanelekileyo, ayifanelekanga kummandla wecala. Oku kwenza isitya esilungileyo sithintela umonakalo kwaye silula xa i-ventricle efanelekileyo ibeka phantsi koxinzelelo lwaluphi uhlobo.
Ngoko, i-block bundle block block iya kuvela kunye nayiphi na imeko echaphazela i-ventricle efanelekileyo. Le miqathango ingabandakanya isifo se-coronary disease (CAD) , i- myocarditis (ukuvuvukala kwesifo senhliziyo), isiphako se-septal defect , i-ventricular septal defect, kunye nesifo senhliziyo se-valvular .
Ukongezelela, isithintelo segatsha esilungileyo singabonwa nangona nayiphi na imiphunga yemiphunga ebangela ukuphakama okungapheliyo kwiingcinezelo ngaphakathi kwe-ventricle efanelekileyo, ngakumbi ingozi yomshukela wegazi . I-pulmonary hypertension, ngokubhekiselele, ingabangelwa ziintlobo zeengxaki ezihlukeneyo zemiphunga, kuquka nesifo esingapheliyo sesifo se-pulmonary (COPD) kunye nokuphazamiseka kokuphazamiseka kokulala .
Ukuphawula, isithintelo segatsha esilungileyo sinokuqhelana nayo nayiphi na imeko ephakamisa iingcinezelo kwi-ventricle efanelekileyo. Isimo esona siqhelekileyo esenza le nto i- pulmonary embolus .
Ngenxa yoko, nabani na ofunyanwa ukuba ne-block buckle block block kufuneka badonwe ngonyango olugxininisa kwimpawu zesifo okanye isifo sephunga. I-x-ray yesifuba kunye ne- echocardiogram ziqhelekileyo-ezisetyenzisiweyo izixhobo zokucoca ngale njongo.
Kungenxa yokuba isebe elifanelekileyo lefestile liyakwazi ukuthintela nantoni na ekwazi ukuvelisa intlungu emfutshane kwi-ventricle efanelekileyo, i-block bundle branch block ibonakala malunga neepesenti ezingama-5 zezigulane ezithatha izidumbu zenyama . Ibloko legatsha lelungelo lelungelo lexeshana lenzeke xa ikhenta icasula isebe elifanelekileyo lefowuni. Le nxalenye yegatsha lexesha elifutshane ihlala isombulula ngokukhawuleza (kwimitha) emva kokuba ishenxiswanga isuswe.
Nangona kunjalo, kubantu abaye bashiya i-block bundle block block, kubangela ukuba le nxalenye yesigqeba segatsha lesigxina sexesha elifanelekileyo iyakwenza i- block ye-heart block epheleleyo , kwaye intliziyo ingayeka ukubetha. Ngoko, kubantu abanesibonda segatsha esisele esisekhohlo abanesigxina se-cardiac catheterization esifanelekileyo, ngamanye amaxesha i- pacemaker yexeshana ifakwe ngexesha leenkqubo, ukuqinisekisa ukuba intliziyo yesigxina iya kuqhubeka ingaphazamiseki ngexesha lokufunda.
Isigqeba soBulungisa saseBaleni kunye nokuPhumelela kwe-Heartbeat
Ngenqabana yesigqeba esisekunene okanye esisekhohlo, iintliziyo zombini zivuselelwa ngokulandelelana (enye emva komnye) endaweni yangexeshana. Ukulahleka kokuqhagamshelana ngokuqhelekileyo phakathi kwee-ventricles ezimbini kunokunciphisa ukusebenza kwentliziyo.
Nangona kunjalo, ukunciphisa intsebenzo yentliziyo yinto encinci kwaye akukho mphumo kwinqanaba legatsha elifanelekileyo. Ngoko, umzekelo, ukusetyenziswa kwonyango yokuguqulwa komzimba (CRT) akukhuthazelwanga kubantu abanebloko yesigqeba eselungileyo, nokuba banesifo senhliziyo .
Ngaba Isigqeba Sesebe Esilungileyo Sifuna I-Pacemaker?
I-block block yesigqeba sokunene, ngokwayo, ayifuneki unyango nge-pacemaker esigxina. Nangona kunjalo, kwezinye iibhloko zecandelo le-branch block ayikho ngokwayo, kodwa kunoko kubonisa ukubonakaliswa kwesinye inkinga ngokubanzi kwenkqubo yokuqhuba umbane. Kwiimeko ezinjalo i-pacemaker ingagqalwa ukuba ifunekayo ukuba i- sinus syndrome okanye i-heart block ibandakanyeke.
ILizwi
Isibonda segatsha sokunene ngokwaso sisimo esibuhlungu esingafuneki unyango. Nangona kunjalo, nabani na ofunyenweyo ukuba babe nalo kufuneka babe nokuphonononga ukuhlola ukulawula ngaphandle kwentliziyo yesifo okanye imiphunga. Ukuba akukho nto ifunyenwe, i-block block yesigqeba esilungileyo isenokuthi ibhalwe phantsi njengento efunyenweyo, kungabikho kubaluleka kwezokwelapha.
