Chii chinodzora kurova yokutama ari atria?

Pacemaker yokutama of atria - mufananidzo cardiac arrhythmia. Arrhythmia mushonga unonzi kutyorwa kwemwoyo, izvo zvinogona kuitwa sezvo wakawedzera kwemwoyo, kumhanyisa, kana deceleration, kana mwoyo rinonzwika iri nguva dzose mapatani kuchengetwa dzapasi Makamuri mwoyo.

Vamwe arrhythmias vanonzi chakakomba mamiriro rinoda vezvokurapa kupindira, nepo vamwe vari zvakajairika chaizvo uye kazhinji havasi kukonzera chikonzero chokunetseka. Kazhinji, Zvikamu zviri vaitamira pacemaker kuti atria regai zvinoda kurapwa, asi kana paine mwoyo kunokonzera murefu kufunganya, zvakanakisisa chiremba kuzosimbisa yakachengeteka ehurumende.

The mashandiro ropa kuyerera

Mwoyo ine mbiri okumusoro (kurudyi nekuruboshwe atrium) uye vaviri ezasi (azvaitwa kurudyi nekuruboshwe ventricles). Ropa runoyerera kuburikidza nzira zvachose kurondedzerwa kuburikidza ose makamera, kuti pave nechokwadi chokuti chakaipa riparadzirwe okisijeni uye zvinovaka muviri rose muviri.

Chokutanga, ropa shoma Vhoriyamu okisijeni asunungurwa dzakasiyana-siyana dzomuviri kupinda zvakanaka atrium, uye ipapo runoyerera kupinda zvakanaka ventricle uye pumped kuna mumapapu. Kamwe zvinoda zvinokosha okisijeni kubva nomumapapu, ropa runoyerera kupinda atrium kuruboshwe, uye ipapo kupinda ventricle kuruboshwe. Zvadaro, oxygenated ropa vaipa kune zvose dzimwe nhengo dzomukati uye dzomuviri.

Basa dzemagetsi pulses

To Anoshanduka ropa pakati pamakamuri, mwoyo tsandanyama vanofanira kuderedzwa. Nemamwe mashoko, atria uye ventricles vari compressed unoitirwa zvakajairika ropa riyerere emwoyo uye muviri wose.

reductions izvi zvinodzorwa ne nomunhu yemagetsi achibva masero chaiwo anokwanisa kuitisa kuitika uye kutumira anonongedzera kune dzimwe masero. Vanovata ndirambe kamuri, vachitevera mumwe mutinhimira uye kakawanda, richipa ropa aibuda utano.

sinoatrial raiva pedyo nebundu

Shoko rokuti "pacemaker yokutama ari atria" rakada kufanana kushanda neboka masero riri pamusoro kurudyi atrium. Masero aya anonzi sinoatrial (sinus) raiva pedyo nebundu uye vane basa nokudzora kakawanda uye mutinhimira zviri zvemagetsi mumwoyo mafungiro. Nokuda kwechikonzero ichi, kuti sinus raiva pedyo nebundu rinonziwo yepanyama pacemaker. Zviri nekuvongwa iye akatanga cardiac marwadzo, vachitevera mumwe mutinhimira uye maitikiro.

atrioventricular raiva pedyo nebundu

Sinoatrial raiva pedyo nebundu hakushandi pachayo - basa rake kubatsira dzakasiyana-siyana zvipenyu zvigadziriswe. Saka, magetsi nomunhu kubva boka iri masero kupinda atrioventricular (atrioventricular) raiva pedyo nebundu, yaiva zvishoma zvakadzika mumwoyo. It transmits anonongedzera kure, achivapa kupinda mwoyo, uye nokudaro, akachengeta synchronous marwadzo mwoyo tsandanyama.

Pacemaker yokutama of atria

Mwana kana akura anogona kuva dzakananga arrhythmia umo mwoyo kuzvidzora magetsi nomunhu kutamira kubva sinoatrial raiva pedyo nebundu kusvika atrioventricular.

Pacemaker yokutama ari atria kunoitika chero nguva, zvisinei basa umo munhu aidaro panguva ino. Kana kunzwisisa arrhythmia zvokuongorora Zvinonzi panguva kudzidzisa zvemitambo uye usiku.

Kazhinji, ayo Kuvapo anenge asina anopa chikonzero chokushushikana. Mune zvimwe zviitiko, pane kuduku kutyorwa mwoyo, asi dzimwe nguva hapana zviratidzo zvokurwara kwakadaro. Munhu hazviwirirani cherechedzai paanouya pacemaker yokutama ari atria.

zvinokonzera njodzi

Izvi rworudzi arrhythmia kunokwanisa kuonekwa mune vanhu vemazera ose, asi kazhinji zviri kuchengetwa mune vakwegura uye vaduku nevana. Kutama zvakare zvakajairika kuti vatambi vari nyanzvi uye vaya vanotsigira muviri wako zvakanaka chaiko chimiro. Zvinokonzera kuti anomaly inoramba isingazivikanwi.

Kazhinji, vanachiremba vanogona kupindura zvinonyatsoteerera chii akakonzera pacemaker yokutama ari atria. Under dzakananga ezvinhu, kureva kakawanda, kutyorwa kunoitika pashure ane ovhadhozi pamusoro cardiac glycosides, kushandiswa pakurapa mamwe zvirwere zvemwoyo.

Diagnostics

A chaiwo pacemaker yokutama ari atria pamusoro ECG (unonzi, electrocardiograph) kunonyanya kuoneka. ECG zvabuda kushanda pakuvheneka nzira zvakafanana akatevedzana mafungu. Pamusoro chinozunguzirwa rinomiririra kodzero atrium rutapudzo anokonzerwa sinoatrial raiva pedyo nebundu. Kana dhayagiramu kune irregularity nemafungu dzakadaro (kuchinja chimiro, kukura uye nzvimbo), chiremba anoita chirwere kuti "pacemaker yokutama ari atria."

Multifokusnaya atrial tachycardia

Kana uchifungidzira kuti une arrhythmia, taronga nachiremba wako se "multifokusnaya (runobva), atrial tachycardia," iri kwakanyanya nechirwere nekukurumidza kubvisa. kukanganisa uku kunonyanya zvakafanana kuti zvinotsanangurwa munyaya ino dambudziko, asi cardiac nodes kutanga nemagetsi nomunhu iyi mhando arrhythmia panguva imwe chete. Somugumisiro anomalous nerevane wakakurumidza kurova kwehana. Multifokusnaya atrial tachycardia iri nengozi uye kunoda nokukurumidza kurapwa.
