Imilenze yesikhwama ihlotshaniswa nesistimu yokuqhuba inhliziyo. Ziklanyelwe ukudlulisa umfutho kagesi kuma-ventricles we-muscle oyinhloko. Le nqwaba iqukethe emuva, kanye nemilenze yangakwesobunxele nesekunene, ukuvimbela okungaholela emiphumeleni engathandeki. Ngamunye wabo unesibopho sayo ingxenye ye-ventricle yesokunxele. Phakathi kwamagatsha kukhona inethiwekhi ye-anastomoses.
Ukuvinjelwa kwegatsha elingaphakathi kwegatsha lesobunxele lensima
Phakathi nalesi simo, i-pathogen yenza ezinhlangothini zangakwesobunxele nangakwesokudla se-septum ye-interventricular. Lapho inqubo ye-ECG idlulela, imiphumela ibonisa izinyo ezijulile S, kanye ne-R. ephezulu Ngesikhathi esifanayo, inani eliphelele liqala ukwehla ngakwesobunxele nangaphezulu. Kungaba nezizathu eziningana zokwenzeka:
- i-infarction ye-myocardial ;
- ukukhushulwa kwe-angina pectoris;
- i-myocarditis;
- Ukushisa komfutho nezinye izinkinga ezichaphazela i-ventricle kwesokunxele.
Izimpawu ezivame kakhulu ziyi:
- scar scar tissue of ventricle kwesokunxele;
- ukuxoshwa kwe-atria;
- ukuvinjelwa kwe-anastomoses phakathi kwamagatsha amabili.
Ukuvinjelwa kwegatsha elihle ngemuva kwegatsha lesobunxele lensiza
Kulesi simo, izimpendulo zidlula egatsheni elingaphakathi futhi zisebenze endaweni ye-lateral ye-ventricle yesokunxele. Ngesikhathi esifanayo, isibonakaliso se-QRS ku-electrocardiogram senyukela phezulu, ngakwesokudla nangaphambili. Kulesi simo, uR uphinde ubonise izinyo eziphezulu, futhi uS - izinyo ezijulile. Ngokuvamile lolu hlobo lokuvimbela luvela ngemva kwe-infarction ye-myocardial ye-ventricle engakwesokunxele noma ngenxa yokuthuthukiswa kwezinkinga nge-arterium artery. Njengemiphumela, i-hypertrophy, ukungakwazi ukusebenza kwe-coronary kuyaqala futhi kukhona umthwalo oqine kakhulu kwi-atrium kwesokunxele.
Gcwalisa ukuvinjelwa kwesibhamu esesobunxele kanye nemiphumela yaso
Endabeni yokuthuthukiswa kwalesi sifo esingathandeki, kuvimbela ukuhamba kwe-pathogen, hhayi ukuyivumela ukuba idlule ngakwesokunxele se-septum. Futhi, indlela eya engxenyeni engakwesokunxele ayitholakali, ngakho-ke isigaba sokuqala senqubo yegazi ayikho. Kulokhu, ukushaywa komlenze wesigunxele kuhamba ngendlela evamile - ukuxhaswa kwe-septum ehamba phambili kuyenzeka ngesikhathi esifanele, ngemuva
Ukuvinjelwa kwegatsha elingakapheli elivinjelwe
Lesi sifo sibonakala njengomphumela wokuziphatha okuphansi komunye wemilenze. Ibonakala ngokuhamba kancane kwe-pathogen kusuka ku-atria kuya kwi-ventricles. Ngenxa yalokho, inqubo ithatha isikhathi esiningi.
