Arrhythmogenic Cardiomyopathy (AC and ARVC)
Arrhythmogenic cardiomyopathy (AC) is a rare inherited heart muscle condition that causes irregular heart rhythms (arrhythmias) at a higher rate than other heart muscle conditions. AC can affect primarily either the left ventricle (Left Dominant Arrhythmogenic Cardiomyopathy) or the right ventricle (Arrhythmogenic Right Ventricular Cardiomyopathy or ARVC). Individuals with AC or ARVC may have symptoms of palpitations or fainting due to arrhythmias. Symptoms may also include shortness of breath due to reduced pumping function of the heart.
