Chii chakasiyana?
Ventricular fibrillation inokonzera kusungwa kwemwoyo, asi kwete kusungwa kwemwoyo kunokonzerwa ne ventricular fibrillation.
Kusungwa kwemwoyo ndiyo izwi rinorondedzera apo mwoyo unorega kuputira ropa zvakapoteredza. Apo mwoyo wemurwere unorega kuputira ropa uye iye anodzima kufema (izvo zvinowanzoitika mukati memaminitsi mashomanana emwoyo inodzima), uyo anourayiwa anoonekwa sechipatara akafa.
Kana mwoyo weanotadza usati watanga zvakare kana CPR haina kutanga mukati memaminitsi makumi mana ekumanikidzwa kwemwoyo, utano hwehupi hunenge huripo hunovimbiswa.
Ventricular fibrillation inoratidziro yemwoyo rhythm mhirizhonga (dysrhythmia) inokonzera kusungwa kwemwoyo. Munguva yemhepo inobhururuka, moyo unorega kurira kazhinji uye unongotanga kudengenyeka. Hapana ropa rinomanikidzwa kuburikidza nokuti hapana chidimbu chekuita.
Tenda kana kwete, kana iwe uchifanira kupinda mumoyo wekusungwa, ventricular fibrillation ndiyo yakanakisisa mamiriro ezvinhu. Ventricular fibrillation inopindura zvakanaka kumagetsi emagetsi, izvo zvinoita kuti kudengenyeka uye kuita kuti mwoyo wekugadzirisa kwemazuva ose utange kupfuura. Ndicho chikonzero nei tichiti mabhokisi ekutyisidzira kwe fibrillator.
Zvimwe Lethal Dysrhythmias
Ventricular fibrillation (v-fib) haisi yega dysrhythmia inokonzera kusungwa kwemwoyo. Kune dzakawanda. Havasi vose vanopindura magetsi sezvakanaka sev-fib.
Chinhu chechipiri chakanaka chinonzi ventricular tachycardia (v-tach) uye inorapwa zvakafanana ne-v-fib. Misiyano ndeyokuti tricycardia ye ventricular inoramba ichiita kuti mwoyo urove nguva dzose, asi inofamba zvakananga zvokuti mwoyo hauwanikwi mukana wezadza neropa. Hapana mukana wekuvaka kukanganiswa, saka ropa rinomira richiyerera.
Asystole ndiro izwi rekushaiwa kwemarudzi ose emwoyo pazvose. Pamusoro pemutambo weKGK, asystole iri nyore, flat flat. Asystole ndiyo yakaipisisa mamiriro ezvinhu nokuti zvinoreva kuti hapana zvachose chakaita magetsi mumoyo chevaponesi kuti vashande pamwe chete. Zvichida ne v-fib kana v-tach, mwoyo unogona kushamiswa, unoita kuti urege kutama kwechipiri uye unopa mukana wokutanga. Funga nezvekudzivirira mafungiro sekugadzirisa mwoyo wako. Hazviwanzoshanda nguva dzose, asi kana zvichita, zvinoshamisa.
Agonal rhythm ishoko rechiito chekupedzisira chemwoyo kuedza kurova. Haibatanidzwi zvakasiyana neye asystole (vanoponesa vanoedza kumutsa mwoyo nekushandisa kusanganiswa kweCPR nemishonga inozivikanwa kuita kuti mwoyo ishungurudzike zvakare). Zvisinei, agonal rhythm zvishoma zvishoma chete nokuti tinoziva mwoyo une zvishoma simba rakasara mairi.
