Ndi pacemaker Kusamuka kwa atria chiyani?

Pacemaker Kusamuka kwa atria wa - choyimira cha arrhythmia mtima. Arrhythmia mankhwala otchedwa kuphwanya kugunda kwa mtima, sipangakhalenso chimaonetsera chinawonjezeka kugunda kwa mtima, mathamangitsidwe kapena deceleration, kapena mtima zikumveka mu ukufanana ndi osasamba anamuona pa m'munsi zipinda za mtima.

Ena arrhythmias akuzindikiridwa monga matenda oopsa zofuna alowererepo zachipatala, pamene ena sizachilendo ndipo samasankha chifukwa chifukwa nkhawa. Nthawi zambiri, nkhani za kusamuka pacemaker ndi atria musati amafuna chithandizo cha mankhwala, koma ngati zachilendo kugunda amachititsa nkhawa mtima, ndi bwino kukaonana ndi dokotala kuti atsimikizire chitetezo cha boma.

Limagwirira wa magazi

The mtima imakhala ya zipinda ziwiri chapamwamba (lamanja ndi kumanzere atrium) ndi kutsikira (ankalemekeza lamanja ndi lamanzere ventricles) awiri. Magazi imaloŵa njira mosamalitsa kumatanthauza kudzera makamera onse, kuonetsetsa kufalitsa yachibadwa mpweya ndi zakudya m'thupi.

Choyamba, mwazi ndi buku kochepa mpweya kumasulidwa ku mbali zosiyanasiyana za thupi mu atrium lamanja, ndiye amalowa ventricle chabwino ndi kupopa m'mapapo. Kamodzi zimatengera mpweya yofunika kwambiri m'mapapo, magazi amalowa atrium kumanzere, ndipo kenako mu ventricle kumanzere. Kenako, magazi mpweya umaperekedwa kwa onse ziwalo zina za m'kati ndi ziwalo.

Udindo wa nyemba magetsi

Kutcheza magazi pakati zipindazo, minofu mtima ayenera kuchepetsedwa. Mu mawu ena, atria ndi ventricles ali wothinikizidwa kuonetsetsa yachibadwa magazi mwa mtima ndi thupi lonse.

kuchepetsedwa awa amene amalamulidwa ndi zikhumbo magetsi kubwera ku maselo yeniyeni angathe kuchititsa panopa ndi kutumiza zizindikiro maselo ena. Amayambitsa amakana chipinda, zotsatirazi kayimbidwe kotani zina ndi pafupipafupi, motero wathanzi magazi.

mfundo sinoatrial

Mawu akuti "pacemaker Kusamuka kwa atria ndi" likugwirizana ndi kugwira ntchito kwa gulu maselo inali pamwamba pa atrium bwino. Maselo amenewa amatchedwa (nkusani) mfundo sinoatrial ndipo ali ndi udindo kulamulira pafupipafupi ndi kayendedwe ka zilakolako za mtima wa magetsi. Pachifukwa ichi, ndi nkusani mfundo umatchedwanso pacemaker achilengedwe. Ndi uyamiko kwa Iye anayambitsa mtima chidule, zotsatirazi kayimbidwe kotani zina ndi pafupipafupi.

mfundo atrioventricular

mfundo Sinoatrial sachiza palokha - ntchito yake zimathandiza kuti zosiyanasiyana njira kwachilengedwenso. Choncho, zilakolako magetsi ku gulu la maselo kulowa atrioventricular (atrioventricular) mfundo, yomwe ili pang'ono zakuya mumtima. Iwo transmits chizindikiro patsogolo, powapatsa kulowa mtima, motero, amasunga synchronous chidule cha minofu mtima.

Pacemaker Kusamuka kwa atria ndi

Mwana kapena wamkulu akhoza kukhala arrhythmia loti mtima kulamulira zilakolako magetsi amayenda ndi mfundo sinoatrial kuti atrioventricular lapansi.

Pacemaker Kusamuka kwa atria kumachitika pa nthawi iliyonse, mosasamala kanthu za ntchito imene munthu chinkhoswe mu nthawi ino. Pamene zovuta matenda arrhythmia ananena pa maphunziro masewera, ndipo usiku.

Monga ulamuliro, pamaso zake pafupifupi konse amapereka kalipokalipo. Nthawi zina, pali zazing'ono kuyan'anila mtima, koma nthawi zina palibe zizindikiro ngati za kudwala. Munthu si munazindikira pamene iye akubwera pacemaker Kusamuka kwa atria lapansi.

Zina mwa zifukwa

Mtundu wa arrhythmia amawapeza anthu a mibadwo yonse, koma nthawi zambiri zimawonedwa mwa ana okalamba ndi ana. Kusamuka ndi Sizachilendo kwa Akatswiri ndi onse omutsatira thupi lako mu mawonekedwe labwino. Zimayambitsa anomaly akhala osadziwika.

Nthawi zambiri, madokotala sangathe kuyankha mosapita m'mbali chimene chapangitsa pacemaker Kusamuka kwa atria lapansi. Mu zochitika zinazake, kuti nthawi ndi nthawi, kuphwanya ndi zikadzatha ndi ambiri osokoneza wa glycosides mtima, ntchito zochizira matenda ena mtima.

diagnostics

A lililonse pacemaker kusamuka kwa atria pa ECG (electrocardiogram) chimaonekera. ECG zotsatira chindodo njira akufanana ndi mndandanda wa mafunde. Pamwamba pa funde amaimira bwino kuchepetsa atrium chifukwa cha mfundo sinoatrial. Ngati chithunzi cha pali irregularity mafunde ngati (kusintha mawonekedwe, kukula ndi malo), dotolo akupanga matenda a "pacemaker Kusamuka kwa atria lapansi."

Multifokusnaya matenda tachycardia

Ngati mukuganiza kuti muli ndi arrhythmia, yokumana ndi dokotala anu kuti "multifokusnaya (wachisokonezo), matenda tachycardia," ikakhala yolemera kwambiri matenda posachedwapa kuthetsa. kuphwanya Izi zimadalira ofanana ndi amene analongosola m'nkhani ino vuto, koma mfundo mtima kuyambitsa zikhumbo magetsi mu mtundu uwu wa arrhythmia nthawi yomweyo. Chifukwa cha ntchito anomalous inapita patsogolo kugunda. Multifokusnaya matenda tachycardia kukumana ndi mavuto ndipo amafuna chithandizo mwamsanga.
