Abstract
Embryocardia is a condition in which the two heart sounds "S" and "S", that produce the typical "lubb-dubb" sound of the heart, becomes indistinguishable and equally spaced. Thus the normal "lubb-dubb" rhythm of the heart becomes a "tic-toc" rhythm resembling the heart sounds of a fetus. This indicates a serious loss of natural fluctuation. This condition is observed in myocarditis.
