Summary

This study tests a 1-month self-management program for people who have recently received a shock from their implantable defibrillator (ICD). The program includes heart rate monitoring and online modules with phone coaching, aiming to reduce anxiety and prevent PTSD. 60 participants are randomly assigned to the program plus usual care or usual care alone, and followed for 6 months.
