Ventricular fibrillation

Ventricular fibrillation (VF) ndi mtima wosazolowereka kwambiri (arrhythmia) womwe umawopseza moyo.

Mtima umapopa magazi kumapapu, ubongo, ndi ziwalo zina. Ngati kugunda kwamtima kwasokonezedwa, ngakhale kwa masekondi ochepa, kungayambitse kukomoka (syncope) kapena kumangidwa kwamtima.

Fibrillation ndi kugwedeza kosalamulirika kapena kunjenjemera kwa ulusi wa minofu (ma fibrils). Ikapezeka m'zipinda zam'munsi mwa mtima, imatchedwa VF. Pakati pa VF, magazi samapopedwa kuchokera mumtima. Zotsatira zakufa kwamwadzidzidzi kwa mtima.

Zomwe zimayambitsa VF ndimatenda amtima. Komabe, VF imatha kuchitika nthawi iliyonse pomwe minofu ya mtima siyipeza mpweya wokwanira. Zomwe zingayambitse VF ndizo:

• Ngozi zamagetsi kapena kuvulala kwa mtima
• Matenda a mtima kapena angina
• Matenda amtima omwe amapezeka pakubadwa (kobadwa nako)
• Matenda amtundu wamtima momwe minofu yamtima imafooka ndikutambasula kapena kunenepa
• Opaleshoni ya mtima
• Imfa yadzidzidzi yamtima (commotio cordis); Nthawi zambiri zimachitika mwa othamanga omwe amenyedwa modzidzimutsa pamalopo pamtima
• Mankhwala
• Potaziyamu wokwera kwambiri kapena wotsika kwambiri m'magazi

Anthu ambiri omwe ali ndi VF alibe mbiri yamatenda amtima. Komabe, nthawi zambiri amakhala ndi ziwopsezo zamatenda amtima, monga kusuta, kuthamanga kwa magazi, ndi matenda ashuga.

Munthu yemwe ali ndi gawo la VF amatha kugwa mwadzidzidzi kapena kukomoka. Izi zimachitika chifukwa ubongo ndi minofu sikulandila magazi kuchokera mumtima.

Zizindikiro zotsatirazi zitha kuchitika mphindi zochepa mpaka ola limodzi kugwa kusanachitike:

• Kupweteka pachifuwa
• Chizungulire
• Nseru
• Kuthamanga kwachangu kapena kosasintha (palpitations)
• Kupuma pang'ono

Kuwunika kwamtima kudzawonetsa kusakhazikika ("kwachisokonezo") kamvekedwe ka mtima.

Mayeso adzachitika kuti ayang'ane chifukwa cha VF.

VF ndichangu mwadzidzidzi. Iyenera kuthandizidwa mwachangu kuti ipulumutse moyo wamunthu.

Imbani 911 kapena nambala yadzidzidzi yakomweko kuti muthandizidwe ngati munthu yemwe ali ndi vuto la VF agwera kunyumba kapena atakomoka.

• Podikirira thandizo, ikani mutu ndi khosi la munthuyo mogwirizana ndi thupi lonse kuti zithandizire kupuma mosavuta. Yambani CPR pochita zipsinjo pachifuwa pakatikati pa chifuwa ("kanikizani mwamphamvu ndikukankhira mwachangu"). Kupsinjika kuyenera kuperekedwa pamlingo wa nthawi 100 mpaka 120 pamphindi. Kuponderezana kuyenera kuchitidwa mozama masentimita awiri koma osapitirira masentimita 6.
• Pitirizani kuchita izi mpaka munthuyo atakhala tcheru kapena athandizidwe.

VF imathandizidwa popereka magetsi mwachangu pachifuwa. Zimachitika pogwiritsa ntchito chida chotchedwa defibrillator yakunja. Kugwedezeka kwamagetsi kumatha kubwezeretsa kugunda kwamtima nthawi yomweyo, ndipo kuyenera kuchitidwa mwachangu momwe zingathere. Malo ambiri apoyera tsopano ali ndi makina awa.

Mankhwala atha kuperekedwa kuti athetse kugunda kwa mtima komanso kugwira ntchito kwa mtima.

An implantable cardioverter defibrillator (ICD) ndichida chomwe chitha kuyikidwa m'chifuwa cha anthu omwe ali pachiwopsezo cha vuto lalikululi ICD imazindikira kugunda kwamtima koopsa ndipo imatumiza mwachangu kuti ikonze. Ndibwino kuti abale ndi abwenzi a anthu omwe adakhalapo ndi VF ndi matenda amtima atenge maphunziro a CPR. Maphunziro a CPR amapezeka kudzera ku American Red Cross, zipatala, kapena American Heart Association.

VF imabweretsa imfa mkati mwa mphindi zochepa pokhapokha itathandizidwa mwachangu komanso moyenera. Ngakhale zili choncho, kupulumuka kwakanthawi kwa anthu omwe amakhala akuvutika ndi VF kunja kwa chipatala ndikotsika.

Anthu omwe apulumuka VF atha kukhala ali chikomokere kapena kukhala ndi ubongo wautali kapena kuwonongeka kwa ziwalo zina.
