ECG kunye ne-myocardial infarction

I-infyoction ye-Myocardial isifo esiqatha esiphumela ngenxa yokubanjwa kwe-lumen yesikebhe esinika igazi kwisisu senhliziyo. Isiphumo salo asixhomeki nje kuphela ngexesha lokubonelela ngononophelo lwonyango, kodwa nangokuchanekileyo kwemisebenzi yokuxilonga. Enye yezifundo ezibalulekileyo kule meko i-electrocardiography yomzimba (ECG).

Ngokusebenzisa indlela ye-ECG, eyenziwa ngeso sixhobo se-cardiograph, iingcali zifumene ebhaliweyo emigqeni ye-wavy ebonisa umsebenzi weentliziyo zomzimba, izikhathi zokuqhawula kunye nokuphumula. Ukuqhutyelwa kwe-electrocardiography kuvumela ukufumana indawo echaphazelekayo, kunye nokubonakalisa indawo ye-perinfarction. Ngokwe-ECG ne-infyoction ye-myocardial, umntu unokugweba indawo kunye nobukhulu be-necrosis ekujoliswe kuyo, landela i-dynamics ye-pathological process.

Uvavanyo lwe-ECG lwe-infyoction ye-myocardial

Ukufundwa kwe-ECG, sele ifunyenwe ngexesha lokuhlaselwa intlungu ye-myocardial infarction, kwiimeko eziqhelekileyo zinokutshintshwa. Ukuvavanya iiparitha zamazinyo, amaqela kunye nezikhathi kwi-electrocardiogram ejongene nomsebenzi weengxenye ezithile zeentliziyo, iingcali ezixilonga ukungahambi kakuhle. Izigaba ze-myocardial infarction kwi-ECG zibonakaliswe ziimpawu ezilandelayo:

1. Isigaba se-Ischemic (ekuqaleni) (ubude - imizuzu engama-20-30) - tine T ekhulisiweyo, ekhomba, ukufuduka kweqela le-ST phezulu.
2. Isigaba somonakalo (ubude - ukususela kwiiyure eziliqela ukuya kwiintsuku ezi-3) kukutshintshwa kwexesha eliphantsi kwe-ST ngaphantsi kwe-isoline, kwaye kuqhutywe phambili ukukhutshwa kwe-ST ngedonga ukuya phezulu, ukwehla kwe-T wave kunye ne-fusion yayo ngexesha le-ST.
3. Isigaba esisemgangathweni (ubude - iiveki 2-3) - ukubonakala kwe-Q wave wave, engaphezulu kweyesine yezinyo R, kunye nobubanzi ngaphezu kwe-0.03; ukunciphisa okanye ukungabikho okupheleleyo kwe-R ukutshatyalaliswa kwesigxina (i-QRS okanye i-QS complex); ukufuduka kwimizi yesimo se-ST ngaphezu kwe-isoline, ukubunjwa kwe-T.
4. Isigaba se-Subacute sesithintelo (ubude - ukuya kwiinyanga eziyi-1.5) - ukubuyisela phambili ukuphuhliswa, okubonakaliswe ukubuyela kwecandelo le-ST ukuya kwi-isoline kunye neentshukumo ezilungileyo ze-T.
5. Isigaba esicacile (siphelela ubomi bonke obusemva) bubunjani be-Q wave waveza, ngelixa i-T wave igxile, ihlaziyiweyo okanye ayibi.

Ukuthembeka kweempawu ze-ECG kwi-infyoction ye-myocardial

Kwezinye iimeko, utshintsho kwi-ECG nge-infyoction ye-myocardial ayikho uphawu, lufunyenwe kamva okanye alukho ngokupheleleyo. Ngokuhlaselwa kweentliziyo eziphindaphindiweyo, ukungaqhelekanga okuqhelekanga kunqabile, kwaye kwezinye izigulane nokuphuculwa kwamanga kwi-electrocardiogram kunokwenzeka. Ngendlela ejoliswe kuyo encinci yesifo, i-ECG iyatshintsha kuphela inxalenye yesigxina ye-ventricular complex, kaninzi ayinakuchasana okanye ayibhalwanga.

Xa izicubu ze-ventricular zonakaliswe, i-ECG i-diagnostics ayikwazi ukusebenza. Ngokuqhelekileyo, i-intracardiac hemodynamics isetyenziselwa ukuvavanya imeko yezi gulane. Kodwa ngamanye amaxesha ne-necrosis ye-muscular ventularular muscle Iziqendu ezongezelelweyo zinokuphakanyiswa ngecandelo le-ST. Indlela yokwenza i-echocardiography yenza ukuba kube lula ukuqikelela ubungakanani besilonda se-ventricle efanelekileyo.

Ubunzima obubalulekileyo ekucaciseni i-ECG emva kokuba i-myocardial infarction ibonakale kwimeko yesimo senhliziyo kunye nokungaphumeleli kokuqhuba (i- paroxysmal tachycardia , ikhutshwe kwinqutyana yesixaka, njl.). Emva koko ukuxilongwa kukucetyiswa ukwenza i-electrocardiogram kwi-dynamics, ngakumbi emva kokuba isigqi sigqityiweyo. Kwakhona, iziphumo ezifunyenweyo kufuneka zifaniswe nedatha yebhubhoratri kunye nezinye iziphumo ezifunyenwe ngumfanekiso weklinikhi.
