Does cognitive behavioral therapy improve psychological adjustment and reduce arrhythmic events requiring shocks in patients receiving an ICD?
Absolute Event Rate: 61% vs 33%

Cognitive behavioral therapy improves psychological adjustment, depression, and anxiety in ICD recipients, particularly among those who receive shocks.
Kohn et al. (2000) conducted an RCT in Patients receiving an implantable cardioverter defibrillator (ICD) (n=49). Cognitive behavioral therapy (CBT) vs. No therapy (NT) was evaluated on Proportion of patients receiving shocks (as part of evaluating arrhythmic events) (p=0.070). Cognitive behavioral therapy for ICD recipients significantly decreased depression (P=0.046) and anxiety (P=0.013) compared to no therapy, though more CBT patients received shocks (61% vs 33%, P=0.070).
