ECG ne myocardial infarction

Myocardial infarction chirwere chakakomba chinokura pamusana pokusvibiswa kwechiedza chemudziyo chinopa ropa kumutsipa wemwoyo. Mugumisiro waro unongogumira kwete kungoita nguva yehupo hwekurapa, asiwo nezvehutano hwezviitiko zvekuongorora. Chimwe chezvidzidzo zvinokosha munyaya ino ndeyemwoyo ye electrocardiography (ECG).

Kuburikidza nenzira yeEECG, yakaitwa nechigadzirwa chema cardiograph, nyanzvi dzinogamuchirwa dzakanyorwa pamapepa emigwagwa yavy inoratidza basa remwoyo wemisungo, nguva dzekudzivirira nekuzorora. Kutevedzwa kwe electrocardiography kunobvumira kuona nzvimbo yakakanganiswa, pamwe nekuzarura nzvimbo ye perinfarction. NeEECG neyomyocardial infarction, munhu anogona kutonga mamiriro ekuma uye ukuru hwekutarisa necrosis, kutevera simba rehutano hwehutano.

ECG kuongororwa kwemyocardial infarction

Kuverenga kweEGG, kwakatowanikwa munguva yekurwadziwa kwekunetseka kwemyocardial infarction, muzviitiko zvinowanzogona kuchinjwa. Kuongorora maitiro emeno, zvikamu uye zvishoma pane electrocardiogram inokonzerwa nebasa rezvikamu zvakasiyana zvemoyo, nyanzvi dzinoongorora hutano husina kunaka. Zvikamu zveMyocardial infarction paEECG zvinoratidzwa nezviratidzo zvinotevera:

1. Ischemic (kutanga) danho (kureba - maminitsi 20-30) - tine T yakawedzerwa, yakaratidza, kushanduka kweS ST chikamu kumusoro.
2. Chikamu chekuvadzwa (nguva - kubva maawa akawanda kusvikira mumazuva matatu) ndiyo kuchinja kwemukati weS ST uri pasi pekudzivirira, uye kuwedzera ST kugadziriswa nedome kusvika kumusoro, kuderera kweT wave uye kuwirirana kwayo neka ST.
3. Pakati payo (nguva - masvondo 2-3) - kuonekwa kwehutano hweH Q, iyo yakadzika kupfuura yechina yezino R, uye upamhi hunopfuura 0.03 s; kuderedza kana kusavapo kwakakwana kweR kuve mumagetsi ekuputika (QRS kana QS complex); kubhururuka kwakagadzikana kwemafuro e ST seboka pamusoro pekunze, kuumbwa kwezvakaipa T.
4. Subacute yero ye infarction (kureba - kusvika pamwedzi miviri) - kudzokera mberi kwekuvandudzwa, inoratidzwa nekudzoka kwechikamu che ST ichienda kune oga uye kune simba rakanaka reT wave.
5. Chiitiko chechiitiko (chinotora hupenyu hwose hutsva) ndiko kuvapo kwehutano hweH Q, apo T wave yakanaka, yakarongedzwa kana isina kunaka.

Kuvimbika kweECG zviratidzo mu myocardial infarction

Mune zvimwe zviitiko, kuchinja muEECG neyomyocardial infarction haisi inhu, inowanikwa gare gare kana zvachose isipo. Nekudzoka kwemoyo kunowanzoitika, kazhinji kusakanganisika kunowanikwa, uye mune vamwe varwere kunyange kuwedzera kwenhema mune electrocardiogram zvinogoneka. Nechidiki-chinotarisa chechirwere, ECG inongotanganisa chete chikamu chekupedzisira chemhepo yakaoma, inowanzove isina uncharacteristic kana kuti isina kunyorwa.

Apo nzira yakarurama ye ventricular inokuvadza, kuongorora kweEECG hakugoni kushandiswa. Kazhinji, hemodynamics inopardiac inoshandiswa kuongorora mamiriro ezvinhu evakadai. Asi dzimwe nguva necrosis yekodzero ye ventricular mus zvimwe zvikamu zvinogona kusimudzwa ne ST segment. Nzira ye echocardiography inoita kuti zviboneke kutarisa zvakajeka kuwanda kwechiremera che ventricle yakarurama.

Zvinetso zvakakosha pakujekesa ECG mushure mekunge myocardial infarction inogona kuonekwa mumamiriro ekushaya mwoyo uye kutadza kwekutengesa ( paroxysmal tachycardia , kubviswa kwechikwata chechikwata, nezvimwewo). Zvadaro nokuda kwekuongororwa zvinokurudzirwa kuti uite electrocardiogram mune simba, kunyanya mushure mokunge rhythm inowanikwa. Uyezve, zviwanikwa zvakawanikwa zvinofanira kufananidzwa nemashoko e laboratori uye zvimwe zvidzidzo zvakaratidzwa nekliniki yemifananidzo.
