Utshintsho phasic ECG in iposi engabalulekanga

Eyona ndlela yokuba une iposi engabalulekanga - uhlalutyo kweekhrayitheriya electrocardiographic-sanctions kwegazi coronary. ECG - uphononongo sele engabalulekanga engqina lokufunyaniswa kwesifo. Yinto indawo nasiphi na esinye, kwakunye ECG kwi ekuvaleni.

iposi engabalulekanga okanye necrosis luphawulwa utshintsho ezidlulayo kweli kwimicu kwezihlunu. inyama Necrotic akathabathi inxaxheba ukuziphatha excitation. Ngoko ke, ECG phezu iindawo necrosis kumiselwa yaphula depolarization le myocardium ventricular, esizibonakalisa kutshintshwe QRS ezintsonkothileyo. Olu tshintsho kukunciphisa R-yomtshangatshangiso kunye kukuqiniswa le Q. izinyo iposi engabalulekanga luphawulwa utshintsho onamandla kule electrocardiogram. Ibonisa ubukho ezintathu imimandla engabalulekanga - central inxenye necrosis, ummandla kukwenzakala engqonge iindawo necrosis kunye ischemia ufumaneka kwindawo engqonge kwindawo eyonakeleyo.

Plot inyama siphazamiseka necrotic iposi engabalulekanga bukugubungele yonke Ebubanzini imisipha eludongeni intliziyo. Oku kubizwa ngokuba transmural engabalulekanga. Ukuba necrosis uphantsi endocardium - subendocardial phantsi epicardium - subepicardial, Ebubanzini imisipha yenhliziyo - intramural.

Le ECG, ngaphandle iintlobo kwezonyango engabalulekanga, waphawula indlela umfanekiso, nto leyo umiselwa ubunzulu emzimbeni, usasazo kunye nokonakaliswa inkqubo umsipha inyathelo. ECG iimpawu engabalulekanga iposi iyohluka, ngokuxhomekeke kwinqanaba kwesi sifo.

Okufana iposi engabalulekanga yahlulwe izigaba ezine: etsolo, etsolo, subacute, kwaye linyathelo loloyiko.

ECG iposi engabalulekanga kwinqanaba oyingozi

Izifo iqala nge nqanaba nokoyika iposi engabalulekanga. Eli lixesha kwathabathela embonakalweni ischemia elibukhali engabalulekanga phambi ukuyilwa iimpawu necrosis. Le ECG, eli nqanaba luphawulwa imbonakalo kwicandelo arcuate wamvusa ST, leyo zidibana kwicala elinye kunye izinyo R, lo gama enye - kunye nezinyo wambumba T. Ngoko i arc eqhelekileyo Pardee iposi engabalulekanga okanye uphawu "emva ikati kaThixo".

ECG iposi engabalulekanga kwinqanaba oyingozi

Kwisigaba nokoyika necrosis engabalulekanga inxenye ekugqibeleni kwasekwa kwaye kuphuhlisa miomalyatsiya (okuthambisa iqhosha basis). Le ECG kwakheka zophendlo lwezifo izinyo Q. ngcembe iba banzi yaye zinzulu, ebonisa kuphuhliso necrosis. Ngaxeshanye imbonakalo amazinyo aqalise ukwehla ST icandelo ezivakalisa izowuni ekunciphiseni umonakalo. Ngelo xesha nye uqalisa ukwakha prong elibi elibukhali T.

ECG iposi engabalulekanga kwi subacute isigaba

Ngexesha subacute isigaba bagqiba iinkqubo okuqala lombutho kwesiva. Eyona iphambili kweli nqanaba, i-ECG linciphileyo kancinane i ST kwicandelo kwaye aya sokugqibela ukuyilwa enzonzobila, macala etsolo, ekuthiwa Izinyo coronary E. Barb Q uzuza ukwakheka kwalo ngeli xesha, nto leyo kuhlala ingatshintshanga kule minyaka kwaye okuhlala kuse ebomini.

ECG iposi engabalulekanga kukuqulungana kwinyathelo

Kukuqulungana yeqonga, itywina kwesiva. Eyona uphawu ngeli thuba i-ST ingxenye indawo kwi kumgca isoelectric. On engabalulekanga ibonisa engaqhelekanga izinyo Q kunye prong T. stably negative Ekuhambeni kwexesha, ixabiso ezimbi T-ngumtshangatshangiso inokuba zithotywe, kusenokuba kubonakale izinyo T. HIV

Xa utshintsho ezincinane ECG iposi engabalulekanga focal kufunwa kancinane lisisiqalo kwi aya ST kwicandelo phezulu okanye ezantsi, kuxhomekeke indawo infarct, kunye T wave inversion

iposi engabalulekanga uvela isikakhulu kwi ventricle ekhohlo. Kwasendaweni of engabalulekanga Iziko necrosis kungqinwa ukubonakala iimpawu electrocardiographic uphawu iposi kwi umkhondo ezichaphazelekayo.
