Ukusebenza kahle kwenhliziyo
Inhliziyo ivame ukumelana kakhulu nomzimba wokulayisha, okwazi ukuqhubeka nomsebenzi wayo ngisho nasezimo ezimbi kakhulu. Isibonelo, i-pulse ingaba kabili, futhi ukukhishwa komzimba - kukhula kane ngaphandle kokuzwa okubuhlungu komuntu, ngaphandle kokuba kuhlale isikhathi eside kakhulu. Into ephawulekayo yukuthi abantu abaningi abahlangabezane nezinkinga zenhliziyo ezinkulu kuze kube sekupheleni kokuphila kwabo. Ukuhluleka kwenhliziyo kungaba umphumela wezifo eziningi ezinciphisa ukukhishwa kwenhliziyo. Izizathu eziyinhloko ziyi:
• Isifo senhliziyo ischemic
Lesi yisifo esivamile kakhulu lapho ukunciphisa imithanguzo ye-coronary kuholela ekunikezeni igazi okwanele ezinsikeni zenhliziyo. Umphumela ungase ube ukwephulwa komzimba (ikakhulukazi ngokuzikhandla ngokomzimba), okuholela ekuthuthukiseni i-angina pectoris.
• Ukushisa komzimba
Abantu abanomfutho wegazi ophakeme bakhulisa ukumelana kwamakhemikhali we-hydrodynamic. Ngenxa yalokho, inhliziyo iyaphoqeleka ukuba ibe nengcindezi eyengeziwe yokugcina ukuhambisa okwanele. Iyakwazi ukubhekana nalolu msebenzi kuphela isikhathi esithile, emva kwalokho ukuthuthukiswa kwenhliziyo okungapheli - umphumela wokukhathala kwe-myocardium, okubangelwa umthwalo owandayo njalo.
• Izifo ze-valve Heart
Lokhu kufaka phakathi i-prolapse (ukwehluleka) kwe-valve, okuholela ekubuyiselweni kabusha (ukuguqula ukukhishwa kwegazi) nokuqina kwesimo (constriction). Kuzo zombili izimo, umthwalo osiswini senhliziyo uyanda. Ingahlawuliswa isikhathi esithile ngokukhulisa ubuningi bezinhliziyo zenhliziyo, kepha uma umkhawulo wamandla wokubuyisela ufinyelelwa, khona-ke ukungakwazi ukuqala ukuthuthukisa.
• Ukuphazamiseka kwemizwa yenhliziyo
Zonke izifo ezibangela ukuphazanyiswa ngesigqi senhliziyo kuthinta umsebenzi jikelele wezinhliziyo. Ngaphezu kwalokho, njengezinye izinqubo eziningi ezibuhlungu emzimbeni, lezi zifo azivame ukubonwa ngaphandle. Isibonelo, ezigulini eziye zahlaselwa isifo senhliziyo, kamuva, ukuphazamiseka kwesigqi kuvame kakhulu. Ukubonakaliswa kokuhluleka kwenhliziyo kungathembela ngokuqinile yiziphi ze-ventricles ezithintekayo.
Ukungaphumeleli kwe-ventricular kwesokudla
Ukuguqulwa kwegazi emjikelezweni omkhulu wegazi kudala ukuvuvukala kwemigqa engezansi, isicanucanu, ukuhlanza, ukubhubhisa (ascites - ukuqoqa oketshezi emgodini wesisu), ukuvimbela nokulahlekelwa amandla. Kungase kube nezibonakaliso zokukhuliswa kwesibindi kanye ne-cyanosis (isibonakaliso sokuntuleka kwe-oksijeni kumathisini).
