Syncope ndi kutayika kwachidziwitso kwakanthawi kochepa komwe kumasiya zokha. Zimachitika chifukwa cha kutsika kwadzidzidzi komanso kwakanthawi m'magazi a ubongo.

Kusowa kwa okosijeni kwakanthawi kochepaku ku ubongo ndikokwanira kupangitsa kutayika kwa chidziwitso ndi kugwa kwa minofu, zomwe zimapangitsa munthuyo kugwa.

Syncope imayimira 1,21% ya ovomerezeka m'chipinda chodzidzimutsa ndipo chifukwa chake chimadziwika mu 75% ya milandu.

Kuti adziwe kuti pakhala syncope, dokotalayo amachokera ku kuyankhulana kwa munthu yemwe anali ndi syncope ndi gulu lake, lomwe limapereka chidziwitso chamtengo wapatali pa zomwe zimayambitsa syncope.

Kuyezetsa kwachipatala kumachitidwanso ndi dokotala, komanso mwina electrocardiogram, ngakhale mayesero ena (electroencephalography) nthawi zonse pofuna kumvetsetsa chifukwa cha syncope iyi.

Kufunsa, kufufuza kwachipatala ndi mayeso owonjezera cholinga chake ndi kusiyanitsa syncope yeniyeni ndi mitundu ina ya kutaya chidziwitso yokhudzana ndi kuledzera ndi mankhwala, mankhwala oopsa, kapena mankhwala osokoneza bongo (mowa, mankhwala), kugwidwa ndi khunyu, sitiroko, kuledzera, hypoglycemia, etc.

Chifukwa cha syncope

Syncope ikhoza kukhala ndi zifukwa zingapo:

• Chiyambi cha reflex, ndiye kuti kwenikweni ndi vasovagal syncope. Reflex syncope iyi imachitika chifukwa cha kukondoweza kwa mitsempha ya vagal, mwachitsanzo chifukwa cha ululu kapena kutengeka mtima kwakukulu, kupsinjika maganizo, kapena kutopa. Kukondoweza kumeneku kumachepetsa kwambiri kugunda kwa mtima komwe kungayambitse syncope. Awa ndi ma syncopes abwino, amasiya okha.
• Arterial hypotension, yomwe imakhudza kwambiri okalamba. Izi ndi orthostatic syncope (panthawi yosintha malo, makamaka pochoka pakugona mpaka kuyima kapena kugwada mpaka kuyima) kapena syncope pambuyo pa chakudya (mutatha kudya).
• A mtima chiyambi, zokhudzana ndi matenda a kangopita mtima kapena matenda a mtima minofu.

Chodziwika kwambiri ndi vasovagal syncope. Zitha kukhudza achinyamata, kuyambira paunyamata ndipo nthawi zambiri timapeza chinthu choyambitsa (kupweteka kwambiri, kutengeka mtima, nkhawa). Choyambitsa ichi kaŵirikaŵiri chimakhala chofanana kwa munthu yemwe wapatsidwayo ndipo kaŵirikaŵiri chimayamba ndi zizindikiro zochenjeza, zimene nthaŵi zambiri zimatheketsa kupeŵa kugwa kowopsa.

Syncope iyi ya vasovagal imakhudzanso okalamba koma, pamenepa, zinthu zomwe zimayambitsa matendawa zimapezeka kawirikawiri ndipo kugwa nthawi zambiri kumakhala koopsa kwambiri (zomwe zingayambitse ngozi ya mafupa).
