Tchacardia yotchedwa Ventricular ndi matenda othamanga kwambiri a mtima ochokera m'mitima ya mtima. Nthawi zina, anthu amalola tricycardia ventricular ndi zizindikiro zochepa chabe. Koma zambiri izi zimapangitsa kuti zikhale zovuta kwambiri, kupweteka kwambiri, syncope (kutaya chidziwitso), kapena kumangidwa kwa mtima ndi imfa mwadzidzidzi.
Zizindikiro zimenezi zimachitika chifukwa tachycardia ya ventricular imasokoneza mphamvu ya mtima kupopera bwino.
Kuchita kupopera kwa mtima kumawonjezereka panthawi ya ventricular tachycardia pa zifukwa ziwiri. Choyamba, kuthamanga kwa mtima pa tachycardia ya ventricular kungakhale mofulumira mokwanira (nthawi zambiri, kupitirira 180 kapena 200 kugunda pamphindi) kuti kuchepetsa mtima. Chachiwiri, tachycardia ya ventricular ingasokoneze chizolowezi chodziwika bwino, chokonzekera, chophatikizana cha minofu ya mtima. Zinthu ziwirizi pamodzi zimapangitsa tachycardia zowopsa kwambiri kukhala ndi mtima woopsa kwambiri.
Kodi Chimachititsa Bwanji Tchacardia?
Nthaŵi zambiri, tricycardia ya ventricular imayamba chifukwa cha matenda osokonezeka mtima omwe amachititsa kuwonongeka kwa mitsempha yam'mimba - kawirikawiri, matenda a mitsempha yotchedwa coronary artery disease (CAD) kapena mtima wosalimba . Mitsempha yofoola komanso yofooka imayamba kupanga maulendo ang'onoang'ono a magetsi mkati mwa minofu ya mtima, maulendo omwe angayambitse " reentrant tachycardias ." Choncho nthawi zambiri tachycardia ya ventricular ndi mtundu wa tachycardia .
Ndipotu, chiopsezo chokhala ndi tachycardia ya ventricular chimakhala chofanana ndi kuchuluka kwa kuwonongeka kwa mitsempha ya ventricular - kuwonongeka koopsa, ndikoopsa kwambiri kwa arrhythmia.
Njira yabwino yowerengera kuchuluka kwa minofu ya mtima ndiyo kuyesa kachigawo kakang'ono kotchedwa ventricular ejection.
Gawo la ejection laling'ono , lowonjezeka kwambiri ndi minofu yowonongeka ndipo imakhala yaikulu kwambiri ya kukhala ndi tricycardia.
Kawirikawiri, tricycardia ya ventricular imatha kupezeka kwa achinyamata omwe amaoneka kuti ali ndi thanzi labwino komanso omwe alibe CAD kapena mtima wosalimba. Nthawi zambiri izi zimayambitsa vuto linalake lachibadwa, kuphatikizapo:
- Matenda a QT aatali
- Kubwereza monomorphic ventricular tachycardia (RMVT)
- Arrhythmogenic bwino ventricular cardiomyopathy (ARVC)
- catecholamine-sensitive polymorphic ventricular tachycardia (CPVT)
- Matenda a Brugada
Kodi Ventricular Tachycardia Yachita Motani?
Maseŵera oopsa a tachycardia (omwe ndi otalikirapo), nthawi zambiri amapezeka mwachangu. Ngati kumangidwa kwa mtima kumakhala kochitika, ndiye kuti njira yowonongeka ya mtima (CPR) iyenera kutengedwa mwamsanga.
Ngati munthu amene ali ndi tachycardia ya ventricular ali wochenjera ndikudzuka ndi kukhala wosasunthika, ndiye kuti njira zowonongeka zingatengedwe. Mwachitsanzo, arrhythmia ikhoza kuthetseratu mwa kupereka mankhwala osokoneza bongo, monga lidocaine. Kapena wodwalayo akhoza kutengeka ndi kupatsidwa mphamvu zamagetsi kuti asiye arrhythmia, ndondomeko yotchedwa "cardioversion."
Pambuyo panthawi yovuta kwambiri ya tricycardia ya ventricular yasiya ndipo mtima wam'bwezero wabwezeretsedwa ku chizolowezi, vuto limapewa mtsogolo. Ichi ndi sitepe yofunikira kuyambira nthawi yomwe munthu wakhala ali ndi chidziwitso cha tachycardia zowonjezereka, zovuta zokhala ndi zochitika zina za chaka chotsatira kapena ziwiri ndizopambana kwambiri - ndipo zochitika zonse zomwe zingakhalepo zingathe kupha moyo.
Njira yoyamba yothetsera tachycardia yodabwitsa kwambiri ndiyo kuyesa ndikuyang'anira matenda oopsa a mtima. Nthaŵi zambiri, izi zikutanthauza kugwiritsa ntchito mankhwala opatsirana kwa CAD kapena mtima kusalimba (kapena onse).
Mwamwayi, ngakhale kuti ali ndi matenda opatsirana kwambiri a matenda a mtima, chiopsezo cha tachycardia zamakono kawirikawiri chimakhala chokwera ndipo, chotero, chimakhala choopsya cha kumangidwa kwa mtima ndi imfa mwadzidzidzi - kotero njira zina ziyenera kutengedwa.
Nthawi zina mankhwala osokoneza bongo amathandizira kupewa tachycardia, koma mwatsoka, mankhwalawa samagwira ntchito bwino. Nthaŵi zina, dera loyambanso kupanga tricycardia likhoza kupangidwanso ndi magetsi ndipo kenako limaphatikizidwa , koma (mosiyana kwambiri ndi odwala ambiri omwe ali ndi tachycardias ) kuposa izi.
Pazifukwa izi, zida zowonongeka zimayenera kuganiziridwa mozama kwa anthu ambiri omwe apulumuka mchitidwe wa tachycardia.
