title: Torsades de pointes and sudden death in a patient with a permanent pacemaker.
abstract: This report describes a patient with a functioning permanent pacemaker who developed torsades de pointes. Although overdrive cardiac pacing has been used to suppress this arrhythmia, cardiac pacing was not protective in this patient. This case also illustrates the difficulty in interpreting Q-T intervals in the presence of paced beats.
