Summary

This study is being done to look at the electrical activity of the heart. This study will help decide whether taking recordings for a 24-hour period gives more useful information than recording it for a few seconds in a doctor's office. The study will compare 24 hour electrocardiogram (ECG) results of patients taking thioridazine (Mellaril) to those of other patients taking different medications that took part in another study.

DEVICE

24 Holter Monitor Recording

All subjects will be fitted with a device to obtain 24-hour Holter EKG continuous recordings of bipolar leads C5C5R. They will also receive a standard 12-lead EKG recording prior to the placement of the Holter device. The subjects will be asked to keep a diary during the course of the 24 hours to record information such as wake and sleep times and symptoms such as shortness of breath, heart palpitations, lightheadedness, etc. From each recording, 12 sets of 10 consecutive QRS epochs, plus QRS samplings obtained during sleep will be analyzed by a cardiologist blind to the medication status of subjects.
