Ventricular fibrillation

Ventricular fibrillation - munhu nokuvhiringidzirwa magetsi webasa ventricular myocardium. Munguva atrial fibrillation (kana flickering) ventricular marwadzo rinomira, zvichiguma cardiac goho anomiswa, kureva, kuparadzirwa ropa, afemeruke, uye murwere anorasikirwa kuziva. The ECG yakanyorwa panguva yakadaro nguva kwemashifiti, kakawanda zvemagetsi oscillations, ane amplitude kuchinja zvinoshamisa. Kana panguva yakadaro nguva murwere nokukurumidza kwete kupedza zvemwoyo yevanorwara zvikuru, zvingangoita, haana vawanezve kuziva.

Kana mwoyo kukundikana muna 70% nyaya yaitika ventricular fibrillation. Uyezve, muna 80% nyaya chikonzero kwakamwe kamwe rufu ventricular fibrillation akanga. The chirwere varume vari katatu kakawanda kupfuura vakadzi.

causation zvirwere

The ruzhinji varwere hosha ikabuda pamberi chomwoyo kana zvimwe non-cardiac zvirwere. Zvikonzero parinowanika kunogona kuva:

- nechirwere chemwoyo;

- dilated cardiomyopathy ;

- kalopatiya;

- hypertrophic cardiomyopathy;

- kudhaka;

- yemagetsi kugwinha;

- hypoxia uye acidosis;

- hypothermia;

- kutora zvimwe mishonga.

Development fibrillation kunosimudzirawo zvinhu zvinoverengeka kuti kuderedza Kugwina myocardium. Zvinhu izvi zvinosanganisira kuwedzera kukura mwoyo, ikawanda tsitsi basa, uye kuvapo foci pakati degeneration uye kuoma dzimwe nhengo dzomuviri ari conduction ino uye myocardial contractility.

yematambudziko

Sezvo ventricular fibrillation kunoitika nomuzvarirwo kazhinji, ayo chikuru kuomesa pasina zvashata kurapwa rufu. Kuti vauye murwere manzwiro kunoda defibrillation. Defibrillation - rudzi "zeroing" mwoyo kupomerwa.

Other yematambudziko zvinosanganisira chido nemabayo, uyewo kukuvara yemapapu kuti zvingaitika pashure pakakuvara mbabvu na nokumutswa.

Panguva cardiac kusungwa, ventricular fibrillation, kureva, dzinenge nguva dzose anova myocardial ischemia, izvo zvinogona postresuscitation kuti matambudziko akadai arrhythmia, myocardial infarction, kana kukundikana electromechanical basa mwoyo.

Kazhinji Varwere pashure ventricular fibrillation akacherechedza uye neurologic matambudziko. Somuenzaniso, anoxic encephalopathy, inova migumisiro chepfungwa hypoxia panguva kurwisa chirwere hwuratidzwe ne convulsive chirwere uye pakoma. Serious uropi panguva cardiac nokumutswa vanobudirira kazhinji. Izvi wakakodzera, kunyanya, kuti chokwadi kuti kusavapo vakabudirira uye zvakanaka Cardiac Intensive matanho mwoyo murwere haasi kutanga.

mabatiro

Treatment, sezvataurwa pamusoro apa, inoumbwa vabudirire nokumutswa murwere. Mamwe kuchirapa zviito vanachiremba zvainanga kudzivisa chirwere kana kwerunyararo uye kudzorerwa murwere simba.

Treatment pakati atrial fibrillation haisi yakananga uye asingauyi kwakasiyana pakurapa ventricles. Mugore yevanenge, varwere vose pashure kurwisa panguva compulsorily zvinoratidza okisijeni kurapa, kureva kuporesa okisijeni.

Hapana kurapwa chaizvo kunobva kurwisa encephalopathy. Muzviitiko izvi, dzehutano kupedza chete symptomatic kurapa, nechinangwa kudzivisa hypotension uye hypoxia, uyewo kusagadzikana carbohydrate uye electrolyte muviri yacho muviri.
