Ventricular fibrillation

Ventricular fibrillation - ka sitiswa tsa tšebetso ea motlakase oa myocardium ventricular. Nakong atrial fibrillation (kapa paitsang) ventricular khutsufatso khaotsa, ho fellang ka khumo cardiac e emisoa, ke hore, ajoa mali, respiration le mokuli ea lahleheloang akheha. The ECG tlalehiloeng linakong joalo kamehla, khafetsa oscillations motlakase, eo liphetoho tse ka tsela e hlollang molumo. Haeba nakong joalo mokuli ka potlako ha ho qeta la pelo tlhokomelo e matla, ho ka etsahala, o ne a sa boele akheha.

Ha pelo ea ho hloleha ka 70% ea linyeoe teng fibrillation ventricular. Ho phaella moo, ka 80% ea linyeoe sesosa sa lefu la tšohanyetso ke ventricular fibrillation ile. The lefu banna ba ka ka makhetlo a mararo hangata ho feta basali.

causation ea lefu

Boholo ba bakuli ba le lefu lena hlaha ka ho ba teng ha lefu la pelo kapa tse ling tse maloetse efe kapa efe bao e seng cardiac. Mabaka a ketsahalo lona e ka ba:

- lefu gogoga pelo;

- dilated cardiomyopathy ;

- kalopatiya;

- hypertrophic cardiomyopathy;

- botahoa;

- makala motlakase;

- hypoxia le acidosis;

- hypothermia;

- noa meriana e itseng.

Ntshetsopeleng fibrillation hape khothalletsa lintlha tse 'maloa tse fokotsa mosebetsi motlakase oa myocardium ena. lintlha tsena li akarelletsa ho eketseha ha boholo ba pelo, e ile ea eketseha mosebetsi le kutloelo-bohloko, 'me ho ba teng ha foci ea degeneration le sclerosis tsamaisong ea conduction le myocardial contractility.

mathata

Kaha ventricular fibrillation le hlaha ka boithatelo ka maemong a mangata, complication ea bona e khōlō ka ho ba sieo ha kalafo tshohanyetso ke lefu. E le hore ho tlisa mokuli maikutlo hloka defibrillation. Defibrillation - ke mofuta oa "zeroing" pelo ea liqoso tseo.

mathata a mang a akarelletsa aspiration ke pneumonia, hammoho le tšenyo e mpe ea matšoafo, le hore ka 'na etsahala ka mor'a fracture ea likhopo ke resuscitation.

Nakong ea ho tšoaroa cardiac, ventricular fibrillation, ke hore,, hoo e ka bang kamehla develops myocardial ischemia, e leng se ka postresuscitation ho mathata a kang arrhythmia, myocardial infarction, kapa ho hlōleha ha electromechanical mosebetsi oa pelo.

Hangata e le ka bakuli ba ka mor'a ventricular fibrillation hlokomela le mathata a neurologic. Mohlala, anoxic magazine, e leng ka lebaka la hypoxia bokong nakong e tlhaselo ea lefu lena le ka 'na ho bonahala ke lefu convulsive le coma. Nka Lintho ka Botebo boko tshenyo nakong resuscitation cardiac atlehileng ka seoelo. Sena ke e loketseng, haholo-holo, ha e le hantle hore ka ho ba sieo ha mehato atleha 'me ba-positive, Cardiac matla pelong ea mokuli a ke ke qala.

kalafo

Kalafo, joalokaha ho boletsoe ka holimo, e entsoe ka resuscitation katleho mokuli. Ba bang kaofela ba bohato phekolo ya basebetsi ya kalafi ikemiseditse ho thibela lefu kapa ho boloka le ho tsosolosoa ha matla a mokuli.

Phekolo ea fibrillation atrial hase itseng 'me ha e fapana ho ea ho phekola ventricles ena. Ka matla unit trust tlhokomelo, bakuli bohle ba ka mor'a hore tlhaselo ka compulsorily ho bontša phekolo oksijene, ke hore, ho folisa oksijene.

Ha ho na phekolo e itseng ka lebaka la ho tlhaselo magazine. Maemong ana, bafani tlhokomelo ea bophelo ba le ho qeta feela ka phekolo bontshang matshwao, e leng e ikemiseditse ho ho thibela hypotension le hypoxia, hammoho le mafu a ea k'habohaedreite le electrolyte metabolism ea phelang.
