ECG phasic mgbanwe myocardial infarction

Isi usoro nke nchoputa nke myocardial infarction - na analysis of electrocardiographic ibiere imebi nke akwara mgbasa. ECG - ihe dị oké ọmụmụ myocardial ikwado nchoputa nke ọrịa. Ọ ike-anọchi ihe ọ bụla ọzọ, nakwa dị ka ECG na blockades.

Myocardial infarction ma ọ bụ necrosis e ji na-akwụsị akwụsị mgbanwe muscle emep uta eri. Necrotic anụ ahụ adịghị ewere akụkụ na omume nke excitation. Ya mere, ECG n'elu ebe nke necrosis kpebisiri ike a mebiri nke depolarization nke ventricular myocardium, nke na-egosipụta mgbanwe nke QRS mgbagwoju. Mgbanwe a bụ iji belata R-efegharị efegharị na anyịnwa ịhụkwu nke nha nha Q. myocardial infarction e ji ike mgbanwe na ngwá. Ọ na-egosi na ọnụnọ nke atọ myocardial zones - Central òkè necrosis, mmerụ mpaghara gburugburu necrosis na ischemia zones nsogbu gburugburu mebiri emebi ebe.

Ibé gbanwere anụ ahụ necrotic myocardial infarction nwere ike ekpuchi dum ọkpụrụkpụ nke obi mgbidi muscle. Nke a na-akpọ a myocardial transmural. Ọ bụrụ na necrosis bụ n'okpuru endocardium - subendocardial n'okpuru epicardium - subepicardial, na ọkpụrụkpụ nke obi muscle - intramural.

The ECG, onwe ha nke na-adakarị iche nke myocardial, kwuru, ihe nakawa etu esi a picture, nke a kpebisiri ike site orunótu omimi, nkesa na mbibi nke obi muscle usoro nzọụkwụ. ECG ịrịba ama nke myocardial infarction iche iche dabere na ogbo nke ọrịa.

Ahụkarị myocardial infarction ekewa anọ nkebi: nnukwu, nnukwu, subacute, na a nzọụkwụ nke n'ichihịa.

ECG myocardial infarction na nnukwu ogbo

Ọrịa amalite na nnukwu ogbo nke myocardial infarction. Nke a bụ oge site na mpụta nke nkọ myocardial ischemia tupu e guzobere ịrịba ama nke necrosis. The ECG, a na ogbo e ji ọdịdị nke welitere arcuate nke ST, nke merges na otu akụkụ na a nha nha R, mgbe ndị ọzọ na - na a eze kpụrụ T. N'ihi ya maka a typical aak Pardee myocardial infarction ma ọ bụ mgbaàmà "cat si azụ".

ECG myocardial infarction na nnukwu ogbo

Na nnukwu-adọ nke myocardial necrosis akpatre kpụrụ òkè ma na-amalite miomalyatsiya (nro gbanwetụrụ infarction). The ECG a kpụrụ enweghị nchịkwa nha nha Q. Ọ nwayọọ nwayọọ na-aghọ obosara na miri emi, na-egosi na mmepe nke necrosis. N'out oge na ọdịdị nke ezé-amalite na-ojuju ST nke na-egosiputa na mmebi Mbelata mpaghara.

ECG myocardial infarction na subacute ogbo

N'oge subacute ogbo dechara nke mbụ Filiks nke nzukọ nke onya.

ECG myocardial infarction onya ke nzọụkwụ

N'apa ogbo, akara nke onya. A mara mma nke a na ogbo bụ ST nke ebe na isoelectric akara. On myocardial egosi ndiiche eze Q na stably ọjọọ prong T. N'ime oge ahụ, uru nke na-adịghị mma T-efegharị efegharị nwere ike belata, ọ pụrụ ọbụna na-egosi nke oma nha nha T.

Myocardial infarction amalite tumadi na ekpe ventricle. Orunótu nke myocardial necrosis n'ekwú pụtara ìhè site n'ile ji mara electrocardiographic ịrịba ama nke infarction na nwoke na-eduga.
