Technology Dependency and Health-Related Quality of Life

This study will explore how people with an implanted cardioverter defibrillator (ICD) feel that dependence on this life-saving technology affects their health-related quality of life. ICD therapy is an important treatment option for patients with serious recurrent abnormal heart rhythms. Overall survival is significantly improved in high risk patients who receive this therapy. This study will explore patients' perceptions of the impact of this device on their health status and well being, and their physical, psychological and social functioning. Patients 18 years of age or older who have an implanted cardioverter defibrillator may be eligible for this study. Participants will fill out a questionnaire booklet containing 170 questions about how they feel about their health, including their concerns and stresses, feelings about dependency on life-saving technology, and illness perception. There are also questions on demography, such as age, marital status, employment, etc. The booklet may take up to 30 minutes to complete. Information obtained from this study may lead to a better understanding of how people feel about their health after receiving an ICD and help patients and families adapt to living with the device.
