Kumanja mtolo chipika nthambi

The anatseka misewu ya mtolo nthambi mapazi bwino chipika - anapeza kuphwanya conduction wa ventricles mtima. Kumachitika mu 0.2% ya achinyamata. Msinkhu, izi pafupipafupi arrhythmia kumawonjezera kuti 0,45%. matenda ili pafupi nthawi zonse amapezeka mu theka wamwamuna wa anthu.

Chinthu chachikulu kuti akapsa chitukuko cha matenda ndi kudwala mtima pa gawo pachimake. Anthu a zaka makumi anai anatseka misewu ya ufulu mwendo mtolo wake wa mtima wabwino alibe mogwirizana ndi kuvutika minofu mtima. Mu zina milandu chitukuko cha ichi mtundu wa arrhythmia amalimbikitsa oopsa (60% ya onse milandu). Nthawi zina iwo amayamba ndi anomalies kobadwa nako (hypoplasia wa koyamba zigawo m'mnyewa wamtima). Komanso, zikamera wa boma anakhudzidwa ndi kukhalapo vuto mtima: zopindika yamitsempha yamagazi, makoma matenda, kuchepetsa m'kamwa mwa mtsempha wamagazi ndi m'mapapo. Thromboembolism wa chidebe, ndi aakulu obstructive khalidwe m'mapapo mwanga matenda kumayambitsa anatambasula za ventricle bwino, zimenezi imautsa maonekedwe a arrhythmias.

Zinthu zomwe zimathandiza kuti chitukuko cha chikhalidwe ichi ndi cardiomyopathy chifuwa yosamveka zoopsa, mwapang'onopang'ono akulu dystrophy, hyperkalemia, mankhwala ambiri osokoneza bongo (novokainamidom, quinidine, mtima glycosides), opaleshoni chiwindi (ofukula ventrikulotomiya), zotupa za mtima, syphiloma. Complete anatseka misewu ya bwino chipika mtolo nthambi ali ndi zizindikiro matenda a matenda amene anayambitsa izo. Ena odwala anatsimikiza mtima kusintha pa auscultation: komanso yogawanika woyamba (zochepa wamba), ndi kamvekedwe chachiwiri (ambiri).

An electrocardiogram wapezeka zotsatirazi i matenda ndi: kuwonjezera zovuta yamitsempha yamagazi, mkulu dzino R, amene anamuona pa kumam'phunzitsa woyamba precordial, serrated R, monga akufotokozera kumanzere amatsogolera dzino kuti ali ndi phindu mosiyana; omwe alinso malangizo S, cha ku Switzerland.

Kumanja mtolo nthambi chipika, mankhwala amene, monga mwina chibwana, sikutanthauza kukonzekera zapadera. Komanso sikutanthauza edokardialnoy kukondoweza, yomwe mu nkhani yachibadwa zachitika pofuna kupewa vuto la matenda a mtima. Ngati ndi kotheka zochizira matenda, chimene nthawizonse kuyambitsa maonekedwe a mtundu umenewu arrhythmia. The anatseka misewu ufulu mtolo chipika nthambi, amapezeka anthu magulu aang'ono zaka, limene palibe zotupa organic a minofu mtima ali ndi madokotala ananena zawo ndi yabwino. Wakutali view wa arrhythmia akhoza konse mu zonse AB AB mfundo anatseka misewu.

Malinga ndi kuphunzira zimenezi, munthawi yomweyo kuvutika awa kukhala ndi kusokonezeka pang'ono conduction ku atria kuti ventricles lapansi. Komabe, n'zotheka kuwonongeka kwa njira yachipatala izi anatseka misewu matenda ndi kuchepetsa nyemba mu pawiri AB. Pamene kuika mtundu wa arrhythmia mwachindunji oopsa, matenda awa ndi kobvuta kwambiri, lethality akukhala mkulu pansi pa zikhalidwe izi. Mbali akumane ndi kukhalapo kwa cardiomegaly, congestive kulephera mtima, systolic elongation nthawi. The anatseka misewu ufulu nthambi mtolo akuwuka pa maziko a infarction m'mnyewa wamtima, pafupifupi konse zipita arrhythmia chilichonse chogwirizana ndi kuphwanya mwa ntchito mu malo AB. Choncho, mtundu wa kudwala ali pafupifupi munthu mkulu mlingo wa imfa. Komabe, pamaso pa mavuto aakulu mtima, iyo ikhoza kwa ankawonjezereka ndi kusokoneza mankhwala, kumene kungakhale inefficient.
