Ezinjalo ezahlukene itheku isigqi

Impendulo yalo mbuzo othi: "Siyini itheku isigqi evamile" iqala ukuhlupha iningi labantu ekwenzeni ukuxilongwa ethize. Kuze kube kuleli qophelo izici ukusebenza inhliziyo akuzona okunabileko. Lesi sihloko ezinemininingwane ukucabangela izoba ngaphansi itheku isigqi.

Jwayelekile umsebenzi inhliziyo inikezwa yi imisebenzi emithathu: excitation, automatism kanye conductivity. Noma yimuphi ukuphambuka kusuka operation evamile lezi zici kungaholela ekwakhiweni izinhlobo ezihlukahlukene zezindwangu ezingaba arrhythmias. Esejwayelekile kwenhliziyo ekhiqizwa e engeyokuqala itheku futhi ubizwa ngokuthi isigqi itheku. Nangodokotela bababhekene nezifo zenhliziyo-akhawunti uphethwe lokuthi isigqi itheku akuyona inkomba operation kahle inhliziyo njalo, abanye izifo zenhliziyo zenzeka ngaphandle arrhythmias inhliziyo. Ngo ezisanda kuzalwa, i esasizosheshisa itheku isigqi, esibalelwa 150 amabhithi, kubhekwa njengento evamile.

Zenhliziyo, okwenza irekhodi phezu cardiogram 'itheku isigqi. Norma ", has engqondweni okulandelayo:

• QRS eziyinkimbinkimbi has a wave P bunjwa njalo;
• Isigqi ukushaya kwenhliziyo kuyinto 60-80 amabhithi;
• Ibanga P-P noma R-R ncamashí.

Igama elithi "iziyaluyalu isigqi itheku" libhekisela arrhythmias futhi blockades. Noma yimuphi nokungezwani e imvamisa, njalo bomsebenzi arrhythmia inhliziyo ngokuthi. Inhliziyo block Lusetshenziswa lapho conduction ephukile ye excitation kusukela maphakathi ngqo imisipha yenhliziyo.

Arrhythmias endaweni ishayela ihlukaniswe dissonance zingaveli ventricles kanye ventricles sekuvele phezu. Phakathi odokotela ngezigaba elandelayo yokutholwa, sibonakalisa engazinzile itheku isigqi:

1. dissonance ishayela ekubumbeni

• Dissonance elihlobene ne-ukwephulwa of automatism, okuhlanganisa itheku tachycardia, bradycardia, arrhythmias;
• Dissonance elihlobene ne ukubusa automatism: isigqi ingasheshi noma yashesha, noma inketho Lesisemkhatsini, lapho inhliziyo ishaya kubambezela futhi isheshisa (ukuhlukumeza we pacemaker);
• Dissonance elihlobene ne-nesenzakalo okuphindiwe ukuqhanyelwa.

2. conduction Dissonance: kulolu hlobo ukwephulwa zihlanganisa zonke izinhlobo ukuvinjelwa.

3. ukwephulwa Kuhlanganiswe

Ukuze sitholakele Udokotela udinga ukuthola umlando wezempilo wesiguli, ukuthola idatha ye izifundo wezinsimbi futhi emtholampilo. Lapho lokuqoqa umlando wenhliziyo izozama ukuthola ulwazi mayelana nokuba khona imikhuba emibi, ufuzo abathuthela kule ndawo nezifo adlulisiwe. Udokotela ucele lapho isiguli lokuqala babezizwa olwaludiliziwe itheku isigqi, lokho emizweni wakuzwa isikhashana. Lezi idatha kuzosiza ukucacisa uhlobo iziyaluyalu: i esasizosheshisa itheku isigqi Isiguli noma okuphambene nalokho, kancane. Isikhathi esining impela, iziguli esekhala kabi esifundeni inhliziyo, emizweni umgomo noma subjective ukuphazamiseka inhliziyo (ukusheshisa noma deceleration). Ngezinye izikhathi arrhythmias kungaba azithalalise yisiguli futhi kungaholela nokulahlekelwa ukwazi. Arrhythmia kaningi ephelezelwa iphika, isicanucanu, ubuthakathaka. Ukucindezeleka womsebenzi inhliziyo kuthinta ukusebenza evamile umgudu wokuphefumula, okuholela yokushodelwa umoya.

Usizo arrhythmias ekuxilongweni has ECG, futhi ukwelashwa kungakusiza ukuba unciphise izimpawu ezingezinhle lesi sifo. Uma ngesikhathi arrhythmias asymptomatic, therapy izidakamizwa ayidingekile for nokugcina ukubaluleka evamile ezisekujuleni kwenhliziyo futhi kulondolozwe contractile yayo umsebenzi. Uma arrhythmias ezithinta ukusebenza evamile, ukuphathwa main kuhloswe ukudala i elilungile electrolyte isizinda ukuqashwa amalungiselelo akhethekile. Uma arrhythmia kungaholela ekufeni isiguli, odokotela abahlinzayo esetshenziswa cardioversion. Ezinye izinhlobo arrhythmias ziphathwa esebenzisa ukuhlinzwa.
