Imilenze yesikhwama ihambelana nenkqubo yokuqhuba i-cardiac. Ziye zenzelwe ukudlulisela umfutho wombane kwii-ventricles ze-muscle. Umxube unamqolo, kunye nemilenze yekhohlo kunye neyekunene, ukukhutshwa kwezinto ezingakhokelela kwimiphumo emibi. Ngamnye wabo unembopheleleko yecandelo layo le-ventricle ekhohlo. Phakathi kwamasebe kunxibelelwano lwe-anastomoses.
Ukuvinjelwa kwegatsha langaphambili legatsha lesekhohlo
Ngeli lizwe, i-pathogen isebenza kumacala asekhohlo nangakwesokudla kwi-septum ye-interventricular. Xa inkqubo ye-ECG idlulayo, iziphumo zibonisa inzondo ejulile S, kunye ne-R. ephakamileyo ngexesha elifanayo, isalathisi esipheleleyo siqala ukuphahlakela ngakwesobunxele nangaphezulu. Kukho izizathu ezininzi zeziganeko:
- i-myocardial infarction ;
- ukunyanzeliswa kwe-angina pectoris;
- myocarditis;
- Uxinzelelo lweengcinezelo kunye nezinye izinto ezimbi ezichaphazela i-ventricle ekhohlo.
Imbonakalo eqhelekileyo yile:
- isiqhwala esisikiweyo se-ventricle ekhohlo;
- i-hypertrophy ye-atria;
- ukukhutshwa kwe-anastomoses phakathi kwamasebe amabini.
Ukuvinjelwa kwesebe elingasemva kwesebe lasekhohlo lensima
Kule meko, iimpembe zidlula kwisebe langaphambili kwaye zisebenze kwindawo yecala le-ventricle ekhohlo. Ngelo xesha, isibonakaliso se-QRS kwi-electrocardiogram sondela, ngasekunene nangaphambili. Kule meko, uR ubonisa inyo ephezulu, kunye ne-S - inyoyi enzulu. Ngokuqhelekileyo olu hlobo lokukhusela luya kwenzeka emva kokuba i-myocardial infarction ye-ventricle engasekhohlo okanye ngenxa yokuphuhliswa kweengxaki kunye ne-pulmonary artery. Njengemiphumo, i-hypertrophy, i-coronary insufficiency ikhula kwaye kukho umthwalo ogqithiseleyo kwi-atrium ekhohlo.
Gcwalisa i-blockade ye-butt bundle butt kunye nemiphumo yayo
Kwimeko yokuphuhliswa kwesi sifo esingathandekiyo, inqanda ukuhamba kwe-pathogen, ukuyivumela ukuba idlule kwicala lasekhohlo le-septum. Kwakhona, indlela eya kwi-ventricle ekhohlo ayifumaneki, ngoko isigaba sokuqala sokunikezelwa kwegazi asikho. Kule meko, i-pulse kumlenze wokunene ihamba ngendlela eqhelekileyo-ukukhutshulwa kwe-septum ye-interamrical ehambelanayo eyenziwa ngexesha elifanelekileyo, emva
I-branch incomplete yefom
Esi sifo sibonakala njengesiphumo solawulo oluphantsi kweminye yemilenze. Ubonakaliswe ukutshatyalaliswa okuthe ngcembe kwe-pathogen kwi-atria ukuya kuma-ventricles. Ngenxa yoko, inkqubo ithatha ixesha elingaphezulu.
