Effects of implantable cardioverter/defibrillator shock and antitachycardia pacing on anxiety and quality of life: A MADIT-RIT substudy

In MADIT-RIT, ≥2 appropriate or inappropriate ICD shocks and ≥2 appropriate ATPs are associated with more anxiety at 9-month follow-up despite no significant changes in the assessment of global QoL by the EQ-5D questionnaire. Innovative ICD programming reducing inappropriate therapies may help deal with patient concerns about the device.
