Arrhythmogenic Right Ventricular Dysplasia

Updated:Sep 12,2014

Arrhythmogenic right ventricular dysplasia (ARVD) is a rare type of cardiomyopathy. ARVD occurs if the muscle tissue in the right ventricle dies and is replaced with scar tissue.

This process disrupts the heart's electrical signals and causes arrhythmias. Symptoms include palpitations and fainting after physical activity. (Palpitations are feelings that your heart is skipping a beat, fluttering, or beating too hard or too fast.)

ARVD usually affects teens or young adults. It can cause sudden cardiac arrest (SCA) in young athletes.
