Those affected by<unk>  may not have any symptoms at all despite having significant abnormalities in the structure of their hearts. If symptoms do occur, the initial presentation is often due to abnormal heart rhythms (arrhythmias) which in<unk>  may take the form of palpitations, or blackouts. Sudden death may be the first presentation of ACM without any preceding symptoms. These symptoms often occur during adolescence and early adulthood, but signs of ACM may rarely be seen in infants. As ACM progresses, the muscle tissue within the ventricles may dilate and weaken. The right ventricle typically weakens first, leading to fatigue and ankle swelling. In the later stages of the disease in which both ventricles are involved shortness of breath may develop, especially when lying flat. The first clinical signs of ACM are usually during adolescence and early adulthood. However, rarely, signs of ACM have been demonstrated in infants.
