ECG phasic liphetoho infarction myocardial

Mokhoa o ka sehloohong oa phumano ya infarction myocardial - the ho hlahloba ka litekanyetso electrocardiographic bakeng sa ditlolo tsa ajoa gogoga. ECG - e ho ithuta bohlokoa haholo ka myocardial e tiisang hore phumano ya lefu lena. E ke ke oa nkeloa sebaka ke tse ling tse leha e le efe, hammoho le ECG ka blockades ena.

Myocardial infarction kapa necrosis e tšoauoa ka liphetoho e fetang ka likhoele mesifa. Necrotic dinama tse nyenyane tse e sa nka karolo boitšoaro ba nyakallo. Ka lebaka leo, ECG fetang libakeng tsa necrosis ikemiselitse ho tlōla le depolarization tsa myocardium ventricular, e bontša ho phetoho ea QRS rarahaneng. Phetoho ena ke ho fokotsa R-e tsokoang le tebisa ya leino Q. Myocardial infarction e tšoauoa ka liphetoho tse matla ka electrocardiogram ena. Ho bontša ho ba teng ha libaka tse tharo myocardial - bohareng karolo necrosis, mo ntša kotsi libaka tse pota-potileng necrosis le ischemia libaka lutse ho pota sebakeng sena senyehileng.

Plot fetoloa dinama tse nyenyane tse necrotic myocardial infarction e ka koahela botenya eohle ea mesifa pelo leboteng. Ena e bitsoa transmural myocardial. Ha necrosis e tlas'a endocardium - subendocardial tlasa epicardium - subepicardial, ka botenya ba mesifa pelo - intramural.

The ECG, nosi tsa liforomo tsa tleleniki ea myocardial, o ile a re dipaterone, litšoantšo, e leng e laolwang ke botebo diriswa, kabo le timetso ea pelo mesifa thulaganyou e mohato. ECG lipontšo tsa myocardial infarction fapana ho itšetlehile ka ho ba sethaleng sa lefu lena.

Tloaelehileng bakeng sa infarction myocardial e arotsoe mekhahlelo e mene: hlobaetsang, a hlobaetsang le, subacute, le mohato oa scarring.

ECG myocardial infarction ka sethaleng a hlobaetsang

Lefu qala ka sethaleng a hlobaetsang ea infarction myocardial. Ena ke nako ea ho tloha ponahalo ea bohale myocardial ischemia pele sebopeho sa lipontšo tsa necrosis. ECG The, mothating ona e tšoauoa ka ponahalo ea e botsitsoeng arcuate karolo ST, eo merges ka lehlakoreng le leng le leino R, ha e mong a - le leino le thehoa T. Kahoo bakeng sa e tloaelehileng ea segopo Pardee myocardial infarction kapa letšoao "katse e khutlela".

ECG myocardial infarction ka sethaleng a hlobaetsang

Ka mohato hlobaetsang ea myocardial necrosis qetella a thehoa kabelo le develops miomalyatsiya (softening fetotsoeng infarction). The ECG Ho thehoa pathological leino Q. O butle-butle e ba sephara le tebileng, e leng se bontšang tsoelo-pele ea necrosis. Ka nako le ponahalo ea meno le qala ho sekama ST karolo e bontša sebakeng tshenyo phokotseho. Ka nako e tšoanang e qala ho ba le e bohale mpe prong T.

ECG myocardial infarction ka sethaleng subacute

Nakong ea sethaleng subacute phethoa le thulaganyo ea pele ea mokhatlo o hlophisitsoeng oa lebali la. The tšobotsi e ka sehloohong ea sethaleng sena, ECG e ea fokotseha butle-butle ka ST karolo le ea moeli ea ho qetela hore ho thehoe le tebileng, ditshwani nchocho, ho thoeng gogoga leino E. Barb Q fumanang sebopeho lona ka nako ena, e leng o hlola ka ho e sa fetohe ka lilemo tse ngata 'me a lulang ho isa bophelong.

ECG myocardial infarction lebali ka mohato

Mokhahlelo oa lebali, tiiso ea lebali e. A tsobotsi bath ea sethaleng sena ke ST karolo sebakeng moleng isoelectric. Ka myocardial bontša e sa tloaelehang leino Q le stably mpe prong T. Ha nako e ntse, boleng ba ntho e mpe T-e tsokoang ka fokotswa, ho ka 'na esita le hlaha positive, leino T.

Ha nyane tsepamiso myocardial infarction liphetoho ECG li felle feela hanyenyane koala ho tswa ho ea moeli ST karolo holimo kapa tlaase, ho itšetlehile ka lefelo la infarct, le T tsokoang pitikololo

Myocardial infarction develops haholo-holo ka ho ventricle letšehali. Diriswa tsa myocardial necrosis leifo pakoang ke ponahalo bath electrocardiographic lipontšo tsa infarction ka itlhomme fapaneng.
