*The identification of a proband with a primary cardiac arrhythmia should trigger screening of family members to identify all affected relatives (presymptomatically). However, considerable heterogeneity may exist in disease manifestation (both in severity as well as differences in disease features) among family members carrying the same mutation. In this respect, a genetic test is vital in uncovering all carriers of the genetic defect within a family. | *The identification of a proband with a primary cardiac arrhythmia should trigger screening of family members to identify all affected relatives (presymptomatically).
