Blockade nke ụkwụ alaka ụlọ ọrụ

Ụkwụ nke nkwonkwo ahụ metụtara usoro mmekọ obi. A na-eme ha iji gosipụta mmetụta eletrik na ventricles nke isi ike. Ngwunye ahụ nwere azụ, yana aka ekpe na aka nri, ihe mgbochi nke a nwere ike iduga na nsogbu ndị na-adịghị mma. Onye ọ bụla n'ime ha nwere ọrụ nke aka ya na ventricle aka ekpe. N'etiti alaka bụ netwọk nke anastomoses.

Blockade nke alaka ụlọ ọrụ nke alaka ụlọ aka ekpe

Na steeti a, ọrịa ahụ na-eme n'akụkụ aka ekpe na akụkụ aka nri nke septum interventricular. Mgbe usoro ECG gafere, nsonaazụ ya na-egosi ezé miri emi S, yana nnukwu elu. N'otu oge ahụ, mkpokọta ntinye amalite ịhapụ n'aka ekpe na n'elu. Enwere ike inwe ọtụtụ ihe kpatara ya:

• nkwonkwo myocardial ;
• exacerbation nke angina pectoris;
• myocarditis;
• Ọrịa elu na nsogbu ndị ọzọ na-emetụta ventricle ekpe.

Ihe ngosi kachasị emetụta bụ:

• ụfụ azụ nke ventricle ekpe;
• hypertrophy nke atria;
• mgbochi nke anastomoses n'etiti alaka abụọ.

Blockade nke na-esote alaka ụlọ ọrụ nke osi n'aka alaka ụlọ ọrụ ahụ

N'okwu a, mkpali ahụ na-agafe alaka ụlọ ọrụ ma na-eme n'akụkụ mpaghara nke ventricle ekpe. N'otu oge ahụ, njirimara QRS na electrocardiogram na-etolite, gaa n'aka nri na n'ihu. N'okwu a, R na-egosikwa ezé dị elu, na S - ezigbo ezé. Ọtụtụ mgbe ụdị nkwụsị a na-eme mgbe mịkọlọtọ myocardial nke ventricle aka ekpe ma ọ bụ n'ihi mmepụta nke nsogbu na akwara pulmonary. Dị ka ihe si na ya pụta, hypertrophy, ọrịa akwara afọ na-amalite ma enwere nnukwu ibu na atrium aka ekpe.

Nkwụsị zuru oke nke aka ekpe ma na ya pụta

N'ihe gbasara mmepe nke ọrịa a na-adighi mma, ọ na-egbochi akụkụ nke pathogen ahụ, ghara ikwe ka ọ gafere n'akụkụ aka ekpe nke septum. Ọzọkwa, ụzọ aka ekpe ventricle adịghịzi adị, n'ihi ya, usoro mbu nke usoro inye ọbara adịghị eme. N'okwu a, mkpịsị ụkwụ aka nri na-aga n'ihu ụzọ - a na - emegharị usoro septum interventricular kwekọrọ na oge kwesịrị ekwesị, mgbe nke na-agafe na-esote. Ọ na-apụta na site na njigide zuru ezu, ntụziaka ahụ agbajiri, ọchịchọ ahụ amalitekwa ịkwaga n'aka nri gaa n'aka ekpe. Ọ bụ nanị ọtụtụ ihe ngosi nke ECG ka a ga-esi amata ọrịa. Ya mere, QRS gafere 0,12 sec, ezé ezé ST na T - na-akwụ ụgwọ.
