Kwisingqi yindibanisela intliziyo izihlunu ukunika oko, abahamba amaqhina kunye besusa. Umzekelo, esiludumbo Sino-atrial ichukumisa umyinge intliziyo, yaye atrioventricular ithumela sazi - a ventricle. ukuphazamiseka Isingqisho kwenzeka ngokufuthi, yaye maxa wambi iba ngumqondiso wokuqala ukugula kakhulu. Olunye uhlobo arrhythmia - it ibetha. iimpawu ngokuqhelekileyo kubonakala ngolu hlobo lulandelayo: kukho ibihlaba esifubeni, elandelwa imvakalelo kwentliziyo ukutshona, okanye isitophu ezimfutshane imizuzwana 1-2. Ngesi ukuphazamiseka isingqisho, yindibanisela kwexesha - extrasystole. Oko akuthethi kuthi esiludumbo sinus, nto leyo umthombo pulses, kwaye kwezinye iindawo izihlunu entliziyweni, myocardium yitile. Emva isishunqulelo engaqhelekanga intliziyo azizaliswanga ngokupheleleyo igazi, kukho unqumamo ethile, ngenxa apho bafunwe ngaphezu ufuna. Emva koko kulandela imveliso eyomeleleyo uyibona. Ngayo le Barr waziva yabantu kakhulu. Ukuba usindwa myocardium, ekuphuhliseni ibetha enzima, iimpawu zesi kakhulu ezithile: ukungabikho ioksijini, isiyezi, ubuthathaka, iintlungu kakhulu entliziyweni.
iintlobo extrasystoles
Kuxhomekeka kukuvela pulses yokuqala isithuba ventricular ecacisiweyo supraventricular (supraventricular) extrasystole. Ukuba zokunciphisa ezinjalo ivela kumthombo ofanayo, zibizwa ngokuba monotopnymi ukuba yahlukile - extrasystoles polytopic. la ngaphambi ungaya omnye emva komnye - zibizwa iwele - okanye emibini okanye emithathu ilandelelana - ivolibholi. beats rhoqo ngaphambi kuyingozi kakhulu kuba kunciphisa ngendlela intliziyo. Ngamana ukuphuhlisa ukusilela intliziyo. Ukuba extrasystoles ventricular (zivela ventricles ngentliziyo), rhoqo yabo ivolibholi angadala fibrillation atrial. Le ukuphazamiseka rhythm ngokuba "ebulalayo". fibrillation Ventricular - isimo esiyingozi. Lubonakala Umsebenzi umbhodamo wentliziyo, apho akukho izinciphiso kunye nemisi. Ukuba fibrillation ithatha imizuzu 5-7, kuya ekugqibeleni kukhokelela ekufeni.
Isifo kwaye afumane unyango
Electrocardiography ukuze ndiyibonakalalise iingxaki isingqi intliziyo kwaye ukucacisa indawo apho kukho ibetha. Iimpawu kule isiguli ulahlekile. Kubalulekile ukuba aqhube ngokupheleleyo iimviwo komzimba, ukuze ukuqonda unobangela ibetha ngaphambi kwexesha. Ngapha koko, kuyabonakala kungekuphela nje ngenxa yesifo sentliziyo. Extrasystole kunokubangela uxinezeleko, isifo luvo, umothuko ingqondo nangezilonda. Unyango kulo mzekelo kufuneka ibhekiswe kwi sifo engundoqo, kunye nadlamkisayo ezifanele nolondolozo oluqhelekileyo intliziyo rhythm. Xa isifo uba ezingapheliyo, amisele iziyobisi antiarrhythmic. Oku kuyinyaniso ngakumbi xa isigulane kutyhilwa arrhythmias supraventricular, iimpawu ezo kuziswa kuye futhi kubuhlungu.
