Deciphering ngakau ECG

Deciphering ECG reliably taea kitea abnormalities i roto i te mahi cardiac, te tūhura i te ānau ki te whakapakoko o te auau ngakau. Hiko-- te ako o te mahi o te mahi cardiac mo te tetahi wā o te wā. whakaata te reira i te tukanga hiko i roto i te uaua ngakau, pērā i depolarization - oaoa, me repolarization - te faaho'iraa mai o ngā pūtau myocardial. i mahi hiko-transthoracic, e ko, na roto i te pouaka, te whakamahi i electrodes whakanohoia ki runga ki te mata kiri, ki te tuhi atu o pānuitanga i runga i te pūrere motuhake. wetemuna tika o ECG whakarato ha faingamālie ki mārama whakapumautia he tātaritanga tika, me te, ki te tika, ki te whakatau i te maimoatanga wā.

Kei o whakapakoko o wāhanga niho me i'ai ECG. Dents cardiogram - ko te wāhi tino o te rārangi ānau e tohu pukapuka Roma characterizing te tohu e whai ake nei: hukihuki Atrial (P), contractions ventricular (Q, R, S) me te ventricular whakangā (T). He tahuri ke, ka tuhia varavara Kāniwha «U». Wāhanga - wāhanga ko te raina tika honotanga nga niho pātata. Ko te nui tino ko te tuhinga o te hiko- i roto i te wāhanga PQ ko ST. Hei tauira, i hanga PQ aho aratau i roto i te wā excitation o roa i roto i te atrioventricular (atrioventricular) kōpuku. Wā - he huinga o niho me wāhanga. Ko te wā tino nui ECG he wā PQ me P- T.

Excitation i roto i te myocardium o nga ventricles ngakau āhuatanga e te ahua i runga i te huinga matatini ECG QRS, no te mea ehara i te mea anake te uaua marae nui, engari ano hoki kua te pakitara wehewehe interventricular. Ko te matatini QRS tuatahi whakatau tata i te rahi o te niho takitahi. reta whakapaipai Ki te nui tīwera poipoi 5 mm, whakaritea te tenei Q, R, ko S, kei hea he iti te kaha tīwera o te motini i roto i te nui, te whakaritea reira reta iti q, r s ranei. Deciphering ECG tā te pānui tika o nga niho. Kāniwha R (r) -, whakahaua ia te whakarunga - no niho pai ki te QRS matatini. Tetahi whakararo - niho kino kei roto i te R niho mua, whakaritea te rite Q (q), me te awa o te R niho - ko te S niho (s). Kāniwha Q faaite te depolarization o te pakitara wehewehe interventricular, infarction myocardial, a kua reira he uara hohonu roa. Kāniwha R tohu depolarization o te nuinga o te myocardium, a ka whakaatu S nga wāhanga niho o mahi Atrial o te pakitara wehewehe interventricular.

Deciphering ECG ngakau ngā o te rangahau pānui rima-ira:

1. Ko te tātaritanga o te auau ngakau , me te kawenga cardiac. Tenei tātari riro periodicity tata auau ngakau, faaotiraa o te auau ngakau (HR), te whakatūnga o te pūtake excitation me te āriponga āhuatanga;

2. whakatau i o te tuaka hiko o te ngātere ngakau;

3. Ako P poipoi Atrial;

4. Ko te ako o te QRST matatini;

5. tātaritanga Opaniraa ECG.

Deciphering ECG ngakau hauora tangata haamata ki te poipoi Atrial poto (AB), e whakaata ana i te huringa i roto i te kaha o nga ventricles ki toto tomo te wa o te systole - hukihuki Atrial. I roto i tenei ngaru hiko-ko ki tua atu i te P-poipoi, me te ka haere ake, e whakaatu ana systole ventricular. Tenei ara pari (b-d) whai te Q niho, me te neke ki te tūnga whakapae (D-e). Ko te wā whakangā o te mānawanawa maui, me te whakaiti pēhanga reira, te ānau koi taka iho (e-g), hāngai wāhi g ki te whakatuwheratanga o te piha mitral me te wiwi o te toto ki nga ventricles. I roto i te ara o te whakaiti, ko te wāhi e hāngai ana ki te ngaohiko o te piha mitral, me te mata o te f, e ōrite ana ki te katinga o te piha te pūtahi o. I muri i te poipoi whakakī puka ngaru systolic ventricular (g-h), me te pōturi ratou ihirangi (k-te). Aru i te huringa tukurua ECG o hauora te ngakau tangata.
