Official title: Effects of Escitalopram on Autonomic Reactivity in Post Traumatic Stress Disorder Among Veterans of Operation Enduring Freedom and Iraqi Freedom (OEF/OIF)

Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

1.To Investigate the Effects of Escitalopram on Cardiac Vagal Function as Measured by R-R Interval Variability, Especially in the HF (0.15-0.5 Hz) Band in OEF/OIF Veterans With PTSD.

To Investigate the Effects of Escitalopram on an Absolute or Relative Decrease in Cardiac Sympathetic Function and Serious Cardiac Side Effects as Measured by QT Interval Variability in OEF/OIF Veterans With PTSD.

Detailed description: The investigators are studying if taking escitalopram will normalize heart rate variability and a decrease (or no effect implying a lack of serious cardiac side effects) including QT variability in veterans with PTSD.
