Ventricular fibrillation

Ventricular fibrillation - a-emeghasịkwa nke eletriki ọrụ nke ventricular myocardium. N'oge atrial fibrillation (ma ọ bụ amụke) ventricular mkpi na-akwụsị, n'ihi na gbasara obi mmepụta kwụsịrị, ya bụ, ọbara, respiration, na ọrịa na-efunari nsụhọ. The ECG dere n'oge ndị dị otú ahụ oge ufodu, Ugboro eletriki oscillations, onye njupụta mgbanwe n'ụzọ dị ịrịba ama. Ọ bụrụ na n'oge ndị dị otú ahụ ọrịa ngwa ngwa bụghị na-emefu obi kpụ ọkụ n'ọnụ na-elekọta, ọ bụ eleghị anya, ọ na-enwetaghachi nsụhọ.

Mgbe obi odida na 70% nke ikpe ime ventricular fibrillation. Ke adianade do, na 80% nke ikpe ihe na-akpata ọnwụ mberede bụ ventricular fibrillation e. The ọrịa bụ ndị na ugboro atọ karịa ndị inyom.

N'oge gbasara obi njide, ventricular fibrillation, ie, fọrọ nke nta mgbe amalite myocardial ischemia, nke nwere ike postresuscitation ka nsogbu ndị dị otú ahụ dị ka arrhythmia, myocardial infarction, ma ọ bụ a ọdịda electromechanical ọrụ nke obi.

Ọtụtụ mgbe, ndị ọrịa mgbe ventricular fibrillation hụrụ na neurologic nsogbu.
