This form of cardiomyopathy is extremely rare in children, and there are usually no signs or symptoms until the teenage or young adult years. Children with arrhythmogenic right ventricular cardiomyopathy (ARVC) usually have symptoms consistent with dilated cardiomyopathy. Those with ARVC may develop abnormal heart rhythms (arrhythmias), which increase the risk of sudden cardiac arrest. The symptoms of ARVC are usually a result of an arrhythmia.
Common ARVC symptoms may include:
Some people with ARVD may develop symptoms of heart failure, which include coughing, vomiting, abdominal pain, shortness of breath, fatigue and weakness, and swelling of legs, feet and abdomen.
