Arrhythmias are diseases that affect the heart's electrical system and the heart's ability to properly squeeze and relax. 2  Hereditary arrhythmias can result in a heartbeat that is too fast, too slow or irregular. 3  They can lead to rapid heartbeat, lightheadedness, dizziness, fainting and sometimes sudden death.
