[Internet therapy for ICD-patients].

Implantable cardioverter-defibrillators (ICD) are increasingly used for the prevention of potentially lethal cardiac arrhythmias due to their confirmed superior medical efficiency. Nevertheless, ICD-patients often suffer from psychosocial problems, e.g., anxiety and depression. These issues are rarely addressed in routine medical follow-up care. Due to the limited mobility of many ICD-patients, Internet-based care may be ideal for delivering psychosocial care to patients in their homes. Our pilot study and case studies illustrate prospects and challenges of this approach. We developed icd-forum.de, a 6-week internet-based prevention program that provides a platform for information, a virtual self-help group, and a professionally moderated chat room in order to help decrease anxiety and to improve quality of life. A critical evaluation in the context of other published studies on the subject allows recommendations for the implementation of future internet-based psychosocial programs for ICD-patients to be deduced. It is the authors' opinion that such programs offer advantages specifically for heart failure patients and they recommend their broader use. Prior to this, conclusive evaluation studies are needed.
