Ventricular fibrillation

Ventricular fibrillation - he hoʻohuikau o ka pou hana o ka ventricular myocardium. Ma atrial fibrillation (ole flickering) ventricular contraction aɃe, kūpono ma cardiac auaiaea ua papani iho la i, i mea, ke koko holo, ka hanu, a me ka hoʻomanawanui haalele i ike. Ka ECG hoʻopaʻa 'iloko o ia manawa ole, pinepine pou oscillations, nona ka ikaika hawewe hoʻololi dramatically. Inā iloko o ia manawa i ka hoʻomanawanui urgently ole, e kali i ka mea'ōnaehana mānowai koko mālama nui malama, e hoʻoneʻe 'ia paha, oia i i • loaʻa paka.

I ka naʻau ole i loko o 70% o ka hihia ana ventricular fibrillation. Eia hou kekahi, ma ka 80% o ka hihia ma ka aoao o ka ulia make ka ventricular fibrillation i. Ke maʻi na kanaka e ma ekolu mau manawa hou pinepine ma mua o nā wāhine.

causation o ka maʻi

Ke uie kekahi hapanui hewahewa o nā mea maʻi i ka maʻi e hoʻomōhala ana i loko o ke alo o ka naau maʻi 'ole kekahi' ē aʻe ole-cardiac kāna hana. Na kumu no kona hanana hiki e:

- coronary naau maʻi;

- dilated cardiomyopathy ;

- kalopatiya;

- hypertrophic cardiomyopathy;

- intoxication;

- uila kŰia;

- hypoxia a me ka acidosis;

- hypothermia;

- e lawe i kekahi mau laau.

Development fibrillation no hoi ka paipai 'ana i ka helu o nā kumumea i emi ai ka pou hana o ka myocardium. Mau kumumea nā i ka hua ma ka nui o ka naau, mahuahua kōkua aloha haʻawina, a me ke alo o ka foci o degeneration a me sclerosis i loko o ka conduction'ōnaehana a me myocardial contractility.

complications

Mai ventricular fibrillation ia lŘlŘ spontaneously i loko o ka hapanui hoopii, kona nui complication i loko o ka wa e kaawale aku o ka pilikia lapaʻau ka make. I mea e lawe mai i ka hoʻomanawanui i ka manaʻo kaumaha pono defibrillation. Defibrillation - mea heʻano o "zeroing" i ka naau o ka 'āhewa' ana.

Other complications nā wehena pneumonia, e like me akemāmā poho i e hana ma hope o fracture o ka iwi aoao ma resuscitation.

Ma cardiac hopu, ventricular fibrillation, 'o ia hoʻi, kokoke mau e hoʻomōhala ana i myocardial ischemia, a hiki postresuscitation i complications e like me arrhythmia, myocardial infarction, a me ka ole i loko o electromechanical hana o ka naau.

Pinepine i loko o nā mea maʻi ma hope o ventricular fibrillation malama a me ka neurologic complications. No ka laʻana, anoxic encephalopathy, i mea heʻilihune o cerebral hypoxia i ka hoouka ana o ka maʻi i e hoikeia e convulsive maʻi pale a me ka coma. Mea lolo poino ma cardiac resuscitation e holomua kākaʻikahi. He manawa, kuhikuhi, a hiki i ka mea i loko o ka wa e kaawale aku o ka holomua a me ka maikaʻi Cardiac mālama nui ana i ka hoʻomanawanui ka naau, e hoʻomaka.

lapaʻau

Iapaau ana, e like me ka olelo maluna, ua i mai o ka holomua resuscitation o ka hoʻomanawanui. Ke koena o ka pākōlea hana o ka 'inikua limahana nona ma pale i ka maʻi a me ka malama a me ka hoihoi hou ia ana o ka hoʻomanawanui ka ikaika.

Lapaʻau o atrial fibrillation mea i ho'ākāka 'ia, a' aʻole i oko mai o ka lapaau ana o na ventricles. I ka mālama nui malama pa alima, a pau nā mea maʻi ma hope o ka hoouka ma ka compulsorily hōʻike o oxygen Inc, oa ka hoola ana i ka oxygen.

'Aʻohe manaʻo nohoʻana mai ana hoouka encephalopathy. Ma kēia hihia, ola malama pūnaewele i e pana aku au i wale i ka symptomatic Inc, i ua nona ma ka Kāohiʻana o ka hypotension a me ka hypoxia, e like me kāna hana o ka carbohydrate a me ka electrolyte pūnao o ka meaola.
