Sažetak

Uvod. Akutni infarkt miokarda karakterišu tipični bol u grudima, promene u elektrokardiogramu u smislu lezije i/ili ishemije miokarda i porast kardiospecifičnih enzima. Dijagnoza je često otežana pri nespecifičnim tegobama, kratkim vremenom od njihovog nastanka i elektrokardiografskim znacima kompletnog bloka leve Hisove grane. Pregled literature. Mnogi autori pokušali su da daju elektrokardiografske kriterijume koji bi u takvoj situaciji mogli sa većom sigurnošću da ukažu na dijagnozu akutnog infarkta miokarda. Najčešće korišćen i priznat jeste Sgarbossa skoring sistem koji uključuje konkordantnu elevaciju ST segmenta > 1 mm, denivelaciju ST segmenta > 1 mm u V1-V3 odvodima i diskorkondantnu elevaciju ST segmenta > 5 mm sa prihvatljivom senzitivnosću i specifičnošću. U kasnijim studijama je senzitivnost i spacifičnost povećana zamenom trećeg kriterijuma sa ST/S odnosom < -0,25. Zaključak. Poznavanjem određenih elektrokardiografskih znakova kod bolesnika sa akutnim koronarnim sindromom i blokom leve grane povećava se mogućnost rane dijagnoze a time i mogućnost bolje i pravovremene terapije.
