Ngokusebenzisa ama-valve ephakathi kokuvuleka kwamagumbi enhliziyo, igazi liyasuswa. Ukuze igazi lingabuyeli emuva, ama-valve avaliwe. Ngokuvamile ukuthuthukisa izifo zabo ezihlukahlukene, enye yezinto eziyingozi kakhulu ukushaywa kwenhliziyo. Kulesi simo, ama-valve awavale ngokuphelele, ngenxa yalokho igazi elibuyiselwe emuva. Lesi sifo sibonakala ngesifiso sokuvuma, kepha ingozi yokucindezeleka iphezulu kakhulu.
I-valve yenhliziyo iyazama
Njengomthetho, lesi sifo asiyona into yokubeletha, kodwa kuvela kuphela ekuphenduleni ukwehluleka komzimba womzimba lapho kukhona izifo. Ngokujwayelekile zenzeka lapho zizalwa futhi kamuva zibuthakathaka isisu senhliziyo.
Kunezizathu ezilandelayo zokuthuthukiswa kwalesi sifo:
- I-Rheumatism. Ukunqotshwa kwezicubu ngokuvamile kwenzeka ngemva kokudluliswa kwe- angina . Kodwa-ke, ukuvuvukala kubuye kwadluliselwa enhliziyweni, izintambo zazo zibhujiswa ngokushesha ngama-bacteria, okugcina ekuholela ekugqibeni kwe-valve yenhliziyo engathathi hlangothi.
- Ukulimala ku-sternum. Ukulimala okungafani kungabangela ukwephulwa kobuqotho bamagobhu e-chord, okwenza kube nezinkinga ezinkulu.
- Ischemia nokuhlaselwa kwenhliziyo. Izifo ezinjalo zibuhlungu kakhulu isimo senhliziyo nokugeleza kwegazi. Ezimweni ezibucayi ukuhlukaniswa kwe-chord kungenzeka.
Izimpawu zenhliziyo ziyazama
Ukugula kuhlale isikhathi eside kungabonakali, futhi kutholakala ekuhlolweni okulandelayo ngokomzimba. Izimpawu ezivame kakhulu:
- umqondo wokuntuleka komoya, isifiso esiqhubekayo sokuthatha umoya ojulile;
- ubuhlungu enhliziyweni , oboniswe ngesipiliyoni sokuphazamiseka noma esimweni sokuthula;
- ukwehluleka kwenhliziyo (i-tachycardia, ilandelwa ukushayela okungavamile);
- ukwanda kokushisa;
- isiyezi, ikhanda ekuseni.
I-prolapse ye-central central valve itholakala ekuhlolisweni, lapho wonke umuntu engaphansi kokuhlolwa komzimba.
