Fibrilace síní (FS), nejčastější supraventrikulární tachykardie, je spojována s přestavbou síňového myokardu, která následně vede ke vzniku abnormalit ve vedení vzruchu síněmi. Jedná se o remodelaci na elektrické, kontraktilní a strukturální úrovni. V předkládané pilotní studii jsme se pokusili ozřejmit souvislost mezi morfologickými (jizvení, amyloidóza, zvětšení levé síně) a elektrofyziologic...
