Ventricular fibrillation

Ventricular fibrillation (VF) inonyanya kukanganisa moyo rhythm (arrhythmia) iyo inotyisidzira hupenyu.

Moyo unopomba ropa kumapapu, huropi, uye dzimwe nhengo. Kana kurova kwemoyo kukakanganiswa, kunyangwe kwemasekondi mashoma, zvinogona kutungamira mukufenda (syncope) kana kusungwa kwemoyo.

Fibrillation kusadzora kusadzora kana kubvunda kwemhasuru fibers (fibrils). Kana zvikaitika mumakamuri epazasi emoyo, inonzi VF. Munguva yeVF, ropa haripombi kubva pamoyo. Kungoerekana kufa kwemoyo kunoguma.

Chikonzero chakajairika cheVF chirwere chemwoyo. Nekudaro, VF inogona kuitika chero nguva tsandanyama yemoyo isingawane oxygen yakakwana. Mamiriro ezvinhu anogona kutungamira kuVF anosanganisira:

• Tsaona dzemagetsi kana kukuvara pamoyo
• Chirwere chemwoyo kana angina
• Chirwere chemwoyo chiripo pakuzvarwa (kuberekwa)
• Chirwere chemoyo wemhasuru umo mhasuru yemwoyo inova isina kusimba uye yakatambanudzwa kana kusimbiswa
• Kuvhiya kwemoyo
• Kamwe kamwe kufa kwemoyo (commotio cordis); kazhinji kacho kunoitika mumitambo iyo yakangoerekana yarova nharaunda yakanangana pamusoro pemoyo
• Mishonga
• Yakakwira kwazvo kana yakaderera kwazvo potasiamu muropa

Vanhu vazhinji vane VF havana nhoroondo yehosha yemoyo. Nekudaro, ivo vanowanzo kuve nechirwere chemoyo chinokonzera njodzi, senge kuputa, kuwedzerwa kweropa, uye chirwere cheshuga.

Munhu ane VF episode anogona kungoerekana adonha kana kuve asina chaanoziva. Izvi zvinoitika nekuti huropi nemhasuru hazvisi kugamuchira ropa kubva pamoyo.

Zviratidzo zvinotevera zvinogona kuitika mukati memaminetsi kusvika 1 awa pamberi pokuwa.

• Kurwadziwa pachifuva
• Dzungu
• Nausea
• Inokurumidza kana isina kujairika kurova kwemoyo (palpitations)
• Kufema kwekufema

Mucherechedzo wemwoyo ucharatidza kusagadzikana ("chaotic") moyo mutinhimira.

Miedzo ichaitwa kutsvaga chikonzero cheiyo VF.

VF chirwere chekukurumidzira. Inofanirwa kurapwa nekukasira kuchengetedza hupenyu hwemunhu.

Fonera 911 kana iyo yemuno emergency emergency kuti ubatsirwe kana munhu ari kuita VF episode akadonha pamba kana kusaziva.

• Paunenge wakamirira rubatsiro, isa musoro wemunhu uye mutsipa mumutsara nemuviri wese kuti ubatsire kuita kuti kufema kuve nyore. Kutanga CPR nekuita kumanikidza kwepfuva pakati pechipfuva ("Pusha nesimba uye Push nekukurumidza"). Kumanikidza kunofanirwa kuendeswa pachiyero che100 kusvika 120 nguva paminiti. Kumanikidza kunofanirwa kuitwa kusvika pakadzika kwemasendimita mashanu asi kwete anopfuura 2 ¼ inches (6 cm).
• Ramba uchiita izvi kudzamara munhu apepuka kana rubatsiro rwasvika.

VF inorapwa nekuendesa nekukurumidza kuvhunduka kwemagetsi kuburikidza nechipfuva. Izvo zvinoitwa uchishandisa chishandiso chinonzi chekunze defibrillator. Kuvhunduka kwemagetsi kunogona pakarepo kudzorera kurova kwemoyo kune yakajairwa mutinhimira, uye kunofanirwa kuitwa nekukurumidza sezvazvinogona. Nzvimbo zhinji dzeveruzhinji dzave nemichina iyi.

Mishonga inogona kupihwa kudzora kurova kwemoyo uye nemoyo basa.

Iyo inodyarwa cardioverter defibrillator (ICD) chishandiso chinogona kuiswa mukati mechipfuva rusvingo rwevanhu vari panjodzi yeiyi yakakomba rhythm kusagadzikana ICD inoona iyo ine ngozi yemoyo rhythm uye nekukurumidza inotumira kushamisika kuti igadzirise iyo. Iri izano rakanaka kune nhengo dzemhuri uye shamwari dzevanhu vane VF uye chirwere chemoyo kutora kosi yeCPR. CPR makosi anowanikwa kuburikidza neAmerican Red Cross, zvipatara, kana iyo American Heart Association.

VF inotungamira kurufu mukati memaminetsi mashoma kutoti ikarapwa nekukurumidza uye nemazvo. Kunyangwe ipapo, kurarama kwenguva refu kwevanhu vanorarama kuburikidza neVF kurwisa kunze kwechipatara kwakaderera.

Vanhu vakapona VF vanogona kunge vari pakoma kana vane hurefu-hurefu hwehuropi kana imwe nhengo yekukuvara.
