Izi mwadzidzidzi paroxysmal tachycardia.

Paroxysmal tachycardia - ndi imodzi mwa mitundu yambiri ya arrhythmias mtima, imene pali kusintha mwadzidzidzi ntchito mtima motsogozedwa kuwonjezeka kugunda kwa mtima. chiwerengero cha mabala kungakhale kuchokera kumenyedwa 140 200 pa mphindi imodzi.

Ndi kusintha pafupipafupi kayendedwe contractile uka matenda osiyanasiyana hemodynamic kuti m'mavuto thanzi la wodwalayo. Pa gawo kuukira kwa diastole wasweka, izo adzafupikitsidwa chifukwa cha ventricles mtima si kokwanira, ndi paroxysm amphamvu ambiri kulibe odzazidwa mwazi. Zonsezi zimayambitsa kuchepa zizindikiro monga sitiroko ndi mphindi buku la magazi. thupi salinso ladzala ndi magazi, kusowa kwake pachimake kumva lakutali ku nyumba m'mnyewa wamtima anatomical - ubongo, impso, matumbo, mapapo. Ngakhale minofu mtima amakhala ndi akusowa lakuthwa magazi ndi mpweya kusungunuka ndi zakudya. Motalikira paroxysmal tachycardia, zoipa adzakhala chithunzi matenda. Chifukwa constriction wa zotumphukira mtima magazi kusokonekera amapezeka amene amayesetsa centralize aziyenda ndi compensatory kuonjezera chochitika kuthamanga. Ngati kuphwanya njira compensatory zingachitike mantha mtima, angina, m'mnyewa wamtima infarction, chifukwa likusintha mofulumira magazi mu mitsempha inatsekeratu kuti kudyetsa mtima. Kusintha kufalitsidwa mu nyumba ubongo kutsogolera kukomoka, mu minofu aimpso - Anura. Long nthawi paroxysmal tachycardia Mwina chifukwa cha necrosis mu matumbo mu Zikavuta kwambiri.

Zikamera wa kuukira mtima paroxysm sikuti kudali amaona odwala okha. Iwo akhoza kunena motsimikiza pamene iyo inayamba, chifukwa Nthawi imeneyo ndinkaona kulikhutchumula lakuthwa m'dera kumbuyo breastbone, ndipo pamene itatha, chifukwa kuukira kutha mwadzidzidzi mawu palpitations. chitsanzo khalidwe la kuukira: wodwala kuyang'ana mantha, wotumbululuka, ozizira, clammy thukuta. Iwo akhoza pa paroxysm a woimba, osati kupeza malo chifukwa cha kuchuluka kwa nkhawa zawo. mitsempha Jugular pathupi kwambiri ndi pulsate nthawi ndi mtima.

Ngati paroxysmal tachycardia odwala ndinayamba yake, posakhalitsa pali mtima kulephera, yomwe ili m'kati ndi sakulabadira kuti kukhudzana mankhwala. Kawirikawiri kusiyanitsa mitundu ziwiri zikuluzikulu za arrhythmias: supraventricular ndi yamitsempha yamagazi. Supraventricular paroxysmal tachycardia ali zambiri zimene mungachite zokhudzana mwadzidzidzi nthenda foci wa automatism, komanso excitations reciprocal. Pamene arrhythmias n'zoopsa kwambiri pamene iwo anayamba kuchepa asynchronously atria ndi ventricles, mwamsanga ndipo refractory mankhwala ndi mtima kulephera.

Paroxysmal tachycardia, chithandizo zimene ziyenera kuchitidwa mwamsanga, ali zingapo zochititsa zokhudza chikhalidwe ndi mtundu wa arrhythmia. Nthawi zina odwala okha angathe kufupikitsa wanu chizindikiro mwadzidzidzi anatuluka. Iwo amagwirizana ndi kanthu reflex pa mitsempha vagus. Mukhoza mapendekeredwe mutu kumbuyo, alemba pa malo ziyerekezo a mtsempha wamagazi ndi carotid, kuyesera kutulutsa kapena pokoka mpweya ndi glottis chatsekedwa, kuti amaumiriza eyeballs ndi mpweya mphira zibaluni, mpira kapena kupukuta nkhope ndi ayezi cubes. Makamaka zabwino kugwira reflex kukhudzana pambuyo kuyambirira kulandira beta-blockers, amene kusauka dzuwa njira zonse izi. mankhwala ikuchitika yekha kuyang'aniridwa ndi dokotala.
