Ifayibrari yomoya

I-Ventricular fibrillation (VF) sisingqisho sentliziyo esingaqhelekanga (arrhythmia) esisongela ubomi.

Intliziyo impompa igazi kwimiphunga, kwingqondo nakwamanye amalungu. Ukuba ukubetha kwentliziyo kuphazamisekile, nokuba kuyimizuzwana embalwa, kunokukhokelela ekuphelelweni lithemba (syncope) okanye ekubanjweni kwentliziyo.

I-Fibrillation kukungalawuleki okungalawulekiyo okanye ukugoqoza kwemicu yemisipha (i-fibrils). Xa isenzeka kumagumbi asezantsi entliziyo, ibizwa ngokuba yi-VF. Ngexesha le-VF, igazi alifakwa entliziyweni. Iziphumo zokufa ngesiquphe kwentliziyo.

Unobangela oqhelekileyo we-VF kukuhlaselwa sisifo sentliziyo. Nangona kunjalo, i-VF inokwenzeka nanini na xa izihlunu zentliziyo zingafumani oksijini yaneleyo. Iimeko ezinokukhokelela kwi-VF zibandakanya:

• Iingozi zombane okanye ukonzakala kwentliziyo
• Ukuhlaselwa yintliziyo okanye i-angina
• Isifo sentliziyo esikhoyo ekuzalweni (kokuzalwa)
• Isifo sentliziyo esihlunu sentliziyo apho isihlunu sentliziyo siba buthathaka khona kwaye solule okanye sijiye
• Utyando lwentliziyo
• Ukufa ngesiquphe kwentliziyo (commotio cordis); okuxhaphakileyo kwenzeka kwiimbaleki eziye zabethwa ngesiquphe kuloo ndawo ngokuthe ngqo ngentliziyo
• Amayeza
• Amanqanaba aphezulu kakhulu okanye asezantsi kakhulu e-potassium egazini

Abantu abaninzi abane-VF abanayo imbali yesifo sentliziyo. Nangona kunjalo, bahlala benesifo sentliziyo, njengokutshaya, uxinzelelo lwegazi kunye neswekile.

Umntu onesiqendu se-VF unokuwa ngesiquphe okanye angabikho zingqondweni. Oku kwenzeka kuba ingqondo kunye nezihlunu azifumani gazi liphuma entliziyweni.

Ezi mpawu zilandelayo zinokwenzeka kwimizuzu ukuya kwi-1 iyure ngaphambi kokuwa:

• Iintlungu zesifuba
• Ukuba nesiyezi
• Isicaphucaphu
• Ukukhawuleza okanye ukungahambi kakuhle kwentliziyo (ukubetha kwentliziyo)
• Ukuqhawukelwa ngumphefumlo

Ukubeka iliso kwintliziyo kuya kubonisa isingqi senhliziyo esingahlelwanga kakuhle ("chaotic").

Kuya kwenziwa iimvavanyo ukukhangela unobangela we-VF.

I-VF ingxamisekileyo kwezonyango. Kufuneka inyangwe ngokukhawuleza ukusindisa ubomi bomntu.

Tsalela umnxeba ku-911 okanye inombolo yongxamiseko yendawo ukuba uncede ukuba umntu onesiqendu se-VF uyadilika ekhaya okanye akazi nto.

• Ngelixa ulinde uncedo, beka intloko nentamo yomntu ngokuhambelana nomzimba wonke ukuze uncede ukwenza ukuphefumla kube lula. Qala i-CPR ngokwenza ukucofa kwesifuba embindini wesifuba ("tyhala ngamandla kwaye utyhale ngokukhawuleza"). Ukucinezelwa kufuneka kusiwe kumgangatho we-100 ukuya kuma-120 amaxesha ngomzuzu. Ukucinezelwa kufuneka kwenziwe kubunzulu beesentimitha ezi-5 ubuncinci kodwa kungabi ngaphezulu kweesentimitha ezi-6.
• Qhubeka nokwenza oku ade umntu abe uphaphile okanye uncedo lufike.

I-VF iphathwa ngokuhambisa ukothuka kombane ngokukhawuleza esifubeni. Kuyenziwa kusetyenziswa isixhobo esibizwa ngokuba sisidibanisi sangaphandle. Umothuko wombane unokubuyisela kwangoko ukubetha kwentliziyo kwisingqi esiqhelekileyo, kwaye kufuneka wenziwe ngokukhawuleza. Iindawo ezininzi zoluntu ngoku zinaba matshini.

Amayeza anokunikwa ukulawula ukubetha kwentliziyo kunye nokusebenza kwentliziyo.

Isixhobo se-cardioverter defibrillator (ICD) esisisixhobo esinokufakwa kudonga lwesifuba sabantu abasemngciphekweni wokuphazamiseka kwesingqi esinobuzaza I-ICD ifumanisa isingqisho sentliziyo esiyingozi kwaye ngokukhawuleza ithumele umothuko ukuyilungisa. Ingumbono olungileyo kumalungu osapho kunye nabahlobo babantu abane-VF kunye nesifo sentliziyo ukuba bathathe ikhosi yeCPR. Iikhosi zeCPR ziyafumaneka kwiAmerican Red Cross, ezibhedlele, okanye kwiAmerican Heart Association.

I-VF iya kukhokelela ekufeni kwisithuba semizuzu embalwa ngaphandle kokuba inyangwa ngokukhawuleza nangokufanelekileyo. Nangona kunjalo, ukuhlala ixesha elide kubantu abaphila ngokuhlaselwa kweVF ngaphandle kwesibhedlele kuphantsi.

Abantu abasindileyo kwi-VF banokuba kwi-coma okanye babe nengqondo yexesha elide okanye omnye umonakalo kumzimba.
