Positive Therapy for Autonomic Function & Mood in ICD Patients

The purpose of this 2-group randomized clinical trial is to: 1) examine the feasibility and acceptability of a 3-month positive-emotion focused therapy (Quality of Life Therapy) modified specifically for patients with implantable cardioverter defibrillator (ICD); and 2) obtain estimates of effect size for QOLT compared to Heart Healthy Education on the changes in arrhythmia frequency and biomarkers of autonomic function, as well as changes in emotion, mood, and well-being across time (baseline, 3 \& 9-months). It is hypothesized that the QOLT will promote improvements in autonomic function, reduced arrhythmia frequency, and improved psychological well-being.
