1 Heart defects. 2  Many heart defects can be detected with an echocardiogram, including problems with the heart chambers, abnormal connections between the heart and major blood vessels, and complex heart defects that are present at birth. 3  Echocardiograms can even be used to monitor a baby's heart development before birth.
Canât regular EKG not detect this heart problem? Regular resting electrocardiogram (with the patient at rest) is only useful if it is positive, if the patient just suffered an acute heart attack, or where actual heart attack is in progress. If the resting EKG is reported as ânormalâ or negative, it does not mean much.
