Ukusebenza kakuhle kwenhliziyo
Intliziyo ngokuqhelekileyo ayixhatshali kumzimba onzima, okwazi ukuqhubeka nomsebenzi wayo nakwiemeko ezimbi. Ngokomzekelo, i-pulse ikwazi ukuphindwa kabini, kunye nemveliso ye-cardiac - ikhule kane ngaphandle kokuvalelwa kowomntu, ngaphandle kokuba ihlala ixesha elide. Into ephawulekayo kukuba abaninzi abantu ababi naziphi na iingxaki ezinzulu zentliziyo kude kube sekupheleni kobomi babo. Ukungaphumeleli kwintliziyo kunokubangelwa zizifo ezininzi ezinciphisa umkhiqizo wentliziyo. Izizathu eziphambili zilandelayo:
• Isifo senhliziyo yesichemicic
Esi sisifo esiqhelekileyo apho ukunciphisa imithwalo ye-coronary arteries kubangela ukuba akukho mali enokwaneleyo ekunikezeni isisu senhliziyo. Isiphumo sinokuphulwa komsebenzi wentliziyo (ngokukodwa ngokuzikhandla ngokomzimba), okukhokelela ekuphuhlisweni kwe-angina pectoris.
• Uxinzelelo lwengqondo
Abantu abanexinzelelo lwegazi eliphezulu banokukhushulwa kwe-hydrodynamic yeenqanawa zomhlaba. Ngenxa yoko, intliziyo inyanzelekile ukuba ikhulise uxinzelelo olungakumbi lokugcina ukujikeleza okwaneleyo. Iyakwazi ukujamelana nalo msebenzi kuphela kwithuba elithile lexesha, emva koko ukuphuhliswa kwentliziyo-ngenxa yokuphelelwa amandla kwe-myocardium, ebangelwa ngumthwalo owandayo rhoqo.
• Izifo zentliziyo ye-valve
Ezi ziquka ukuguquka (ukungaphumeleli) kwevavve, okuphumela ekubuyiselweni kwakhona (ukuguqula igazi) kunye ne-stenosis (constriction). Kuzo zombini iimeko, umthwalo kwi-heart muscle uyanda. Ingakwazi ukuhlawulelwa ixesha elithile ngokunyusa ubunzima beentliziyo zeentliziyo, kodwa xa umda we-compensatory capacity ufikeleleke, ngoko ukungafuneki kuqale ukuphuhlisa.
• Ukuphazamiseka kwentliziyo
Zonke izifo ezibangela ukuphazamiseka kwisigxina senhliziyo kuthintela umsebenzi jikelele wenhliziyo. Ngaphezu koko, njengaye nezinye iinkqubo ezibuhlungu emzimbeni, ezi zifo aziqhelwanga ukuba zodwa. Ngokomzekelo, kwizigulane eziye zahlaselwa yintliziyo, kamva, ukuphazamiseka kwesigqithiso kuninzi. Ukubonakaliswa kwentsikelelo yeentliziyo kunokuxhomekeke ngokukodwa kwii-ventricles ezichaphazelekayo.
Ukungaphumeleli kwamandla okusebenza
Ukutshatyalaliswa kwegazi kwisangqa esikhulu sokujikeleza kwegazi kubangelwa ukuvuvukala kweengcambu eziphantsi, isisongela, ukuhlanza, ukuqhaqhawula (ascites - ukuqokelela umkhuhlane kwisisu esiswini), ukuvimba nokulahleka kwamandla. Kukho izibonakaliso zokwandiswa kwesibindi kunye ne-cyanosis (isibonakaliso sokungabikho kwe-oksijini kwimizimba).
