Mlingo ECG zizindikiro zazikulu

Electrocardiography ndi yofunika si olanda njira Kupeza Vuto ntchito zinchito za mtima. Bukuli lili ndi kulembetsa wa Zoyenereza magetsi kuchepetsa infarction, amene anasonyeza pa zenera kapena pepala.

The kafukufuku amasonyeza oopsa, kupweteka m'chifuwa ndi kufupika kwa mpweya, pambuyo zaka 40, kusuta ndiponso mafuta m'thupi, patsogolo ntchito iliyonse, pa mimba ndipo pambuyo matenda.

Kuti akachite zinthu electrocardiogram ntchito yapadera chipangizo - electrocardiograph ndi maelekitirodi ndi ziwalo.

ECG zambiri yodziwika ndi zinthu zotsatirazi:

1. Mano amene anatchulidwa zilembo P, Q, R, ndipo S, T, U.

Tikumbukenso kuti dzino P akusonyeza mmene malemeredwe wa atria lapansi. Mwachibadwa, anakhala - kuchokera 0.06-0.1 matalikidwe - 0.05-2.5 mm.

Pamene ECG mlingo anatsimikiza za kanjedza kuti kachigawo lalikulu osachepera pa pepala, mmene Zoyenereza magetsi a mtima zalembedwa, ndi masekondi 0,04, ndi kutalika limafanana ndi voteji wa 0,1 millivolts.

mlingo ECG mano ena:

• Q dzino kutalika ayenera kukhala <0,03 ndi Voteji ndi - <¼ yoweyula matalikidwe kwa R;

• R dzino akhale 0.03-0.04 ndi 20 mm (V5 ndi V6 akhoza ziwonjezeke kwa 26);

• S - nthawi wabwinobwino wa yoweyula ukufika 0,03 m, ndi voteji - <8 kutsogolera Ine II, V1 angakhale <25;

• ECG: yachibadwa dzino T-0,16 gawo ndi matalikidwe - <1/2 yoweyula R;

• U - ponseponse - 0,06-16 ndi kutalika kwa yoweyula akhale za 2-3 mm.

2. mosinthanasinthana: PQ (zimachitika limafanana ndimeyi pakati pa atrium ndi ventricle), QT, ndi rr, cha ku Switzerland. Last imeneyi ndi T yoweyula amadziwika repolarization, amene chikuchitika mu ventricles za mtima;

3. The zovuta anali ayesedwa QRST, kusonyeza systole magetsi ndi ventricles.

Pakuti kulembetsa kwa zikhumbo za magetsi mu myocardium a muyezo atatu ntchito, komanso zitatu anaumitsa zisanu ndi chimodzi ECG pachifuwa amatsogolera. Ponseponse zotsatira amadalira atigwira imene nthawi ndi matalikidwe ya mafunde.

Tikumbukenso kuti ECG ndi wapatali kwambiri matenda njira. ECG mlingo wa zinthu zonse zimasonyeza wa nthawi zonse ndiponso moyenera pafupipafupi contractions wa mtima, komanso yachibadwa kugwira ntchito kwa dalaivala wa mungoli. Mu kusintha zina Tingaone pa pamaso pa arrhythmias, mtima conduction chisokonezo kapena kuyan'anila mwina perfusion m'mnyewa wamtima ndi ischemia.

ECG mlingo matalikidwe n'kofunika kuti matenda zolondola, kuyambira kuchuluka kwake n'zotheka kulankhula za hypertrophy zigawo zowonjezera za mtima, zimene akufotokozera matenda oopsa ndi matenda ena mtima.

Ine ndiyenera kunena kuti ECG ndi zotchipa komanso nkhani matenda njira, koma drawback zikuluzikulu - yochepa nthawi ya kalembera wa zikhumbo magetsi, amene amafalitsidwa ndi minofu mtima. Sikutheka kuti azindikire ndi chisokonezo nthawi za mtima. Kudziwa kuvutika ngati electrocardiography polojekiti ntchito yomwe imachitika kwa maola 48 ndipo amapereka chithunzi thunzi chokwanira zambiri za ntchito kwa myocardium lapansi.

Komanso, chifukwa ndi masiyanidwe matenda a matenda a organic ndi zinchito mu mtima zikhoza kuchitidwa ECG orthostatic katundu kapena hyperventilation, komanso pa makonzedwe a formulations osiyana (mankhwala zitsanzo).
