Torsades de pointes and sudden death in a patient with a permanent pacemaker.

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.
