Anorova, zvinangwa zvavo

Anorova - ichi mhando arrhythmia, nekuratidzwa somugumisiro zvemamiriro automaticity uye kuzodzosera Pindai mashandiro hworatidza pacharo mukutanga kwemwoyo kana madhipatimendi ayo. Anorova, chikonzero uye nzvimbo mangwanani dzishande akasiyana. Zvichienderana nzvimbo chitarisiko Munokudzwa: atrial, ventricular vakurumidze anorova uye marwadzo kuitika atrioventricular Junction.

Rinobinha, zvinokonzera ayo pakutsvaga paaizooneka, anodana mangwanani uye kunonoka. The nguva inopfuura kubva rapfuura yakatarwa kusvikira anorova itsva, rinonzi predektopichesky penguva (coupling nguva). Ari zvachose wakaiswa, zvichiratidza nevakawanda tsime mangwanani dzishande. Gogonera pakureba zvikamu chokuita extrasystoles nzvimbo dzakasiyana. Izvi anoshandura chimiro chavo.

The pedyo kubatana pakati chitarisiko mangwanani sunga uye chikuru mutinhimira mumoyo anokonzerwa chidzoke zvinoshamisa incentives chikuru (romuzvarirwo) kupomba - postdepolyarizatsii mashandiro, asynchronous repolarization kana kuzodzosera Pindai.

Properties extrasystoles manotsi uye haizopereri kumbomira ndiyo nguva penguva kuti inopfuura pakati mangwanani kuderera uye haizopereri kupomba anokosha mutinhimira. Nguva yose kumbomira kunoenderana kana paiva kuerera kubva sinus raiva pedyo nebundu. Pamusoro kokuyerera ectopic sinus raiva pedyo nebundu kupomba izvo zvakaita kubva mangwanani atrial excitation, mutsva zvairatidza anotanga kuumba mairi nguva penguva akaenzana inokosha sinus mutinhimira. Zvino kukosha chi- uye postektopicheskogo zvikamu huchiderera pane vaviri kuipa cardiac zvinogara, zvisakakwana compensatory kumbomira. Kana zvinoyerera huru ungano arrythmia kunoitika, pane yokumbozorora chakakwana, ndiko kuti, Verengai chi- uye postektopicheskih zvikamu akaenzana ya vaviri vakakwana cardiac zvinogara.

Anorova, avo zvinokonzera, kusarudza kakawanda uye paaizooneka yavo. Nguva nenguva mangwanani rutapudzo (somuenzaniso, anorova pashure zvokudya) akanga rakapotsa hapana zvazvinoita hemodynamics, asi dzimwe nguva vangava prognostic kukosha, kuva harbinger zvekare kuzvikanganiso arrhythmias. Constant anorova, rakatumbuka pamwe kuipa mutinhimira, kuoma neropa chokubuda chepfungwa. Kana zvitatu anotevedzana chinyorwa vakurumidze sunga, izvi zviri sokureva paroxysm kuti tachycardia. Pangava fibrillation mumwoyo, kana varipo vokutanga vakurumidze sunga, pamwe kutyorwa metabolic pezvakaitwa vari myocardium.

Early marwadzo kuitika atrium, pakaita akaratidza P wave, inova vakasiyana kwomuzvarirwo chimiro uye refu. QRS kunzwisisa pachayo inoramba zvakafanana. Kuderera kwemitambo ventricular-atrial remubatanidzwa pamusoro cardiogram kuonekwa zvakachinjwa ventricular yakaoma. P zino chakashayikwa, sezvo excitation rinobatana atrial ventricular excitation. Kana ventricular marwadzo kunoitika atrial P chinozunguzirwa pamberi akaipa uye rinowanika mushure ventricular yakaoma.

Early marwadzo ose ventricles pamusoro cardiogram kuonekwa sezvo mangwanani ventricular yakaoma rine supraventricular chimiro. Asati extrasystole hapana P wave, ventricular zvivako kuwedzerwa uye kushandurwa. Anorova kuruboshwe ventricle ngapaonekwe blockade rworudyi chinogumbura tsapo bazi ndiEzekieri.

reductions Early anogona kuenda chero mwoyo chirwere, asi angaita pachavo, nokuda zvirwere tsinga zvinodhaka ovhadhozi, electrolyte kusaenzana, doro akawanda.

How kubvisa pamusoro arrhythmia

Zvakakosha kubvisa zvinhu zvose kuti pave mangwanani rutapudzo. Rongera anonyaradza tsinga zvinodhaka. Rare mavanga regai zvinoda vavashandire. Kana pamwe neBP extrasystoles ushandiswe antihypertensive uye zvinodhaka antiarrhythmic (propranolol, verapamil, et unto.), Potassium zvokuwedzera, kana pasina contraindications kwazviri.
