Ibigize n'akamaro bya ECG iyobora imirongo

1. Amaguru arayobora

Harimo ingingo isanzwe iyobora I, II, na III hamwe no kwikuramo unipolar ingingo iyobora aVR, aVL, na aVF.

.

.Muri iki gihe, amplitude ya flimform yakozwe ni nto, bityo igitutu gikoreshwa mukongera ubushobozi bwapimwe kugirango byoroshye kumenyekana.

. igihimba, na electrode yicyatsi iri kumaguru no kuguru k'ibumoso bwo hepfo.Electrode yirabura iherereye ku kaguru k'iburyo bwo hepfo.

Isanduku irayobora

Nibiyobora unipolar, harimo kuyobora V1 kuri V6.Mugihe cyo kwipimisha, electrode nziza igomba gushyirwa mugice cyagenwe cyurukuta rwigituza, kandi electrode 3 ziyobora ingingo zigomba guhuzwa na electrode mbi binyuze mumashanyarazi 5 K kugirango ikore itumanaho rikuru.

Mugihe cyibizamini bisanzwe bya ECG, 12 biyobora bipolar, igitutu cya unipolar ingingo ziyobora hamwe na V1 ～ V6 birashobora guhaza ibikenewe.Niba dextrocardia, hypertrophy iburyo bwiburyo, cyangwa infarction ya myocardial ikekwa, kongerwamo V7, V8, V9, na V3R.V7 iri kurwego rwa V4 kumurongo wibumoso winyuma;V8 iri kurwego rwa V4 kumurongo wibumoso;V9 iri kuruhande rwumugongo wibumoso Umurongo V4 uri kurwego;V3R iri ku gice gihuye na V3 ku gituza cy'iburyo.

Gukurikirana akamaro

1. Sisitemu 12-yo gukurikirana sisitemu irashobora kwerekana myocardial ischemia ibyabaye mugihe.70% kugeza 90% bya ischemia ya myocardial igaragazwa na electrocardiogram, kandi mubuvuzi, akenshi usanga idafite ibimenyetso.

2. Ku barwayi bafite ibyago byo kurwara myocardial ischemia, nka angina idahindagurika hamwe na infirasiyo ya myocardial, 12-bayobora ST-segment ikomeza gukurikirana ECG irashobora guhita itahura ibyabaye bikabije bya myocardial ischemia, cyane cyane ibyorezo bya myocardial ischemia, bikaba ari ivuriro Tanga ishingiro ryizewe ryo kwisuzumisha mugihe gikwiye. no kuvurwa.

3. Biragoye gutandukanya neza tachycardia yumuyaga na tachycardia ya supraventricular hamwe nuyoboro utandukanye ukoresheje imiyoboro ya II gusa.Inzira nziza yo gutandukanya neza byombi ni V na MCL (complexe ya P na QRS ifite morphologie isobanutse).

4. Iyo usuzumye injyana idasanzwe yumutima, gukoresha inzira nyinshi nukuri kuruta gukoresha icyerekezo kimwe.

5. Sisitemu yo kugenzura 12-isobanutse neza kandi mugihe cyo kumenya niba umurwayi afite arththmia kuruta sisitemu gakondo yo kugenzura imwe imwe, kimwe nubwoko bwa arththmia, igipimo cyo gutangira, igihe cyo kugaragara, igihe bimara, nimpinduka mbere na nyuma kuvura ibiyobyabwenge.

6. Gukurikirana 12-kuyobora ECG ni ngombwa cyane mukumenya imiterere ya arththmia, guhitamo uburyo bwo gusuzuma no kuvura, no kureba ingaruka zubuvuzi.

7. Sisitemu 12-yo kugenzura nayo ifite aho igarukira mubikorwa byubuvuzi, kandi irashobora kwivanga.Iyo umubiri wumurwayi uhindutse cyangwa electrode ikoreshwa mugihe runaka, imiyoboro myinshi yo kwivanga izagaragara kuri ecran, bizagira ingaruka kumucamanza no gusesengura electrocardiogram.
