A patient with a left ventricular assist device (LVAD) presented with violent nocturnal limb movements during sleep. This sleep-related movement disorder-repetitive ballistic movements (RBMs)-underscores the importance of identification of nocturnal movements, their relationship to sleep, and to potential catastrophic consequences in susceptible patients.
