ECG phasic kusintha infarction m'mnyewa wamtima

The njira yaikulu ya matenda a infarction m'mnyewa wamtima - ndi kusanthula i electrocardiographic kwa kuyan'anila za kufalitsa inatsekeratu. ECG - kuphunzira singasiyanitsidwe mu m'mnyewa wamtima natsimikiza matenda a matenda. Iwo akhoza m'malo ndi wina aliyense, komanso ECG pa blockades lapansi.

M'mnyewa wamtima infarction kapena necrosis amakhala ndi kusintha chosakhalitsa mu ulusi minofu. Necrotic minofu satenga mbali mu khalidwe la malemeredwe. Choncho, ECG m'madera a necrosis anatsimikiza kuphwanya depolarization wa myocardium yamitsempha yamagazi, amene amadera kusintha kwa QRS zovuta. Kusinthaku ndi kuchepetsa R-yoweyula ndi kuzama kwa dzino Q. m'mnyewa wamtima infarction amakhala ndi kusintha wochitachita mu electrocardiogram lapansi. Izo zikusonyeza kukhalapo kwa mabacteria atatu m'mnyewa wamtima - chapakati gawo necrosis, kuvulala zone ozungulira necrosis ndi ischemia mabacteria Chilwa kuzungulira bwalo zowonongeka.

Chiwembu adasandulika minofu necrotic m'mnyewa wamtima infarction akhoza kuphimba makulidwe lonse la minofu mtima khoma. Amenewa amatchedwa transmural m'mnyewa wamtima. Ngati necrosis ndi pansi endocardium - subendocardial pansi pa epicardium - subepicardial, mu makulidwe a minofu mtima - intramural.

The ECG, popanda njira matenda a m'mnyewa wamtima, anati dongosolo chithunzi, amene anatsimikiza ndi kuya kutanthauzira, kugawa ndi chiwonongeko cha mtima minofu ndondomeko sitepe. ECG zizindikiro za m'mnyewa wamtima infarction ikhoza kusintha kutengera siteji ya matenda.

Chitsanzo cha infarction m'mnyewa wamtima lagawidwa magawo anayi: pachimake, pachimake, subacute, ndi sitepe ya amamuyambitsa timabala.

ECG m'mnyewa wamtima infarction mu gawo pachimake

Disease akuyamba ndi gawo wokonda infarction m'mnyewa wamtima. Izi ndi nthawi maonekedwe a lakuthwa m'mnyewa wamtima ischemia pamaso mapangidwe zizindikiro za necrosis. ECG The, nthawi imeneyi amakhala ndi maonekedwe a anakweza arcuate gawo cha ku Switzerland, imene merges mbali imodzi ndi dzino R pamene winayo - ndi dzino linapangidwa T. Zitanthauzanso lililonse Arc Pardee m'mnyewa wamtima infarction kapena chizindikiro "mphaka kalero".

ECG m'mnyewa wamtima infarction mu gawo pachimake

Mu gawo pachimake cha m'mnyewa wamtima necrosis potsiriza anapanga gawo ndipo umakula miomalyatsiya (pokonza kusinthidwa infarction). The ECG aumbike pathological dzino Q. Iye pang'onopang'ono chachitali komanso chozama, kusonyeza kuti chitukuko cha necrosis. Imodzi ndi maonekedwe a mano ayamba kuchepa cha ku Switzerland gawo limene limasonyeza zoni kuwonongeka kuchepetsa. Pa nthawi yomweyo amayamba lakuthwa zoipa prong T.

ECG m'mnyewa wamtima infarction mu siteji subacute

Pa siteji subacute anamaliza njira yoyamba ya gulu la chilonda. Mbali yaikulu ya gawo lino, ECG ndi kuchepa pang'onopang'ono ndi cha ku Switzerland gawo ndi mizere komaliza kwa mapangidwe kwambiri, symmetrical wosongoka, otchedwa inatsekeratu dzino E. waminga Q amapeza mawonekedwe ake pa nthawi ino, zimene zatsalira zikutsatiridwa kwa zaka zambiri chopereka moyo.

ECG m'mnyewa wamtima infarction chilonda mu sitepe

Mbali chilonda, chisindikizo cha chilonda. Mbali khalidwe la gawo ili ndi cha ku Switzerland gawo malo pa mzere isoelectric. Pa m'mnyewa wamtima limasonyeza nthenda dzino Q ndi stably zoipa prong T. M'kupita kwa nthawi, mtengo wa zoipa T-yoweyula mwina kuchepetsedwa, nthawi zina zimakhala zosangalatsa dzino T.

Pamene yaing'ono focal m'mnyewa wamtima infarction kusintha ECG okha pang'ono kuchepetsa ku mizere cha ku Switzerland gawo kapena pansi, malingana ndi malo infarct, ndipo T yoweyula inversion

M'mnyewa wamtima infarction akufotokozera makamaka ventricle kumanzere. Kutanthauzira kwa m'mnyewa wamtima necrosis moto umboni ndi maonekedwe khalidwe electrocardiographic zizindikiro za infarction mu kumam'phunzitsa ziwalo.
