Ukuphazamiseka conduction intraventricular zenhliziyo.

I zokugula we esimiso senhliziyo nemithambo yegazi manje ezihambayo endaweni yokuqala phakathi kwawo wonke amanye ezivamile.

Bambalwa abantu ezweni lanamuhla ongakaze ezwe isigqi iziyaluyalu yisimiso senhliziyo nemithambo yegazi. Lezi izimo zokucabanga okubangelwa isifo zihlanganisa, futhi ukuphazamiseka conduction intraventricular zenhliziyo.

Ukwephula wathi conductivity akusona ukungabi khona ukudlula emsipheni amaza. Lokhu isimo kubonisa ukuhlukumeza e povodyaschey uhlelo ezingasetshenziswa ukuzibonakalisa njengoba pulses deceleration imvamisa ukudluliswa (kanye deceleration isilinganiso, ngokulandelana) kanye ukumisa okuphelele ukudlula pulses (ukuboshwa inhliziyo). Ngakho, ukuphazamiseka conduction intraventricular wenhliziyo wabonakaliswa inhliziyo block. Ngakho, bahlukene zibe ephelele (engenakwenzeka ukudlula yisifiso emsipheni) futhi akuphelele lapho ezinzwa amaza ziqhutshwa nge imvamisa kancane.

Ngaphezu kwalokho, ukuphazamiseka intraventricular conduction inhliziyo ingahlinzwa bahlukaniswe indawo izilonda (isib nokuvinjelwa kwesokunene noma kwesobunxele block besigaxa-legatsha). Vele wonke ukuvinjelwa zingahlukaniswa zibe proximal futhi distal. Lapho kuziwa izingxenye distal we izinzwa ijwabu inhliziyo, mancane evumayo nangenkathi ezifuna ukunakwa okukhulu kusukela udokotela.

Enye ngezigaba samuntu blockades: eziphikelelayo (esingamahlalakhona noma eziphikelelayo) futhi eziphelayo (acute noma ingazinzi).

Izizathu ezingabangela ukuphazamiseka conduction intraventricular wenhliziyo zingahlukaniswa ngezigaba ezintathu eziyinhloko: organic, ukusebenza kanye okwelapha.

Organic - ngokushintsha isakhiwo sale inhliziyo conduction uhlelo. Izinguquko ezinjalo, ngakho kungavuka myocarditis, isifo senhliziyo (ukuhlaselwa isifo senhliziyo, angina, infarction, nabanye), ukukhubazeka azalwa naso, cardiomyopathies, futhi ngezinye izikhathi ngemva kokuhlinzwa.

izinguquko Functional - izinguquko inhliziyo conduction uhlelo ngokungabi bikho organic zokugula CCC. I izinhlelo main olawula umsebenzi lo inhliziyo conduction uhlelo kukhona izinhlelo nozwela futhi parasympathetic. Kulokhu, ohlelweni onozwela kwandisa conductivity futhi parasympathetic - siyehla. Ngo operation evamile lwalezi nhlelo ezimbili Nokho, kuyalingana, ne ukungalingani waphawula izinguquko ukusebenza uhlelo senhliziyo nemithambo yegazi. Ukwandisa kohlelo parasympathetic - "vagotonia".

Izidakamizwa imbangela ngenxa. Leli qembu kuhlanganisa izidakamizwa, ogama umsebenzi kungadala ukuphambuka isigqi inhliziyo. Isici yalesi blockades iqembu sinzima kakhulu ngesikhathi kanye nokwelashwa torpid (kobukhulu).

Ukwephulwa conduction intraventricular sitholakale ngokusebenzisa indlela electrocardiographic. Ephambi kwezinduna arrhythmias lezivakashi kwenziwe inguqulo olukhethekile ECG izifundo - ukuqapha Holter.

Ngokwe-ECG ejwayelekile kunzima ukuba wahlulele indawo, ngakho ukuze kucaciswe khona proximal noma ukuvinjelwa distal eyenziwa ukubhaliswa besigaxa yakhe electrogram (EPG).

Ukuthola ukubandakanywa isimiso sezinzwa (the nozwela futhi parasimpatiki) ekuzwakaliseni ukuvinjelwa kwenziwe umsebenzi ukubekezelelana test.

Ngakho, sitholakele isifo senhliziyo manje eyenzelwe ngokucacile kakhulu futhi ngokunembile, okukuvumela kalula ukuhlonza ukuphazamiseka conduction intraventricular zenhliziyo. Ukwelashwa nokuvikelwa leli qembu izifo ngokuyinhloko ngenxa isici etiological. Okungukuthi, abangabantwana ukwelashwa endaweni yokuqala kufanele okuhloswe ngalo ukuqeda izimbangela nokuvinjelwa futhi okwesibili kuphela - ukwelashwa lingaze.
