In view of the inceasing number of implanted defibrillators in all industrial nations, the number of people who have suffered so-called multiple shocks (electrical storm, ES) also increases. Common complaints are severe and continuously recurrent massive anxiety, panic attacks, fear of death, helplessness and hopelessness, depression, nervosity and irritability as well as reclusive and uncontrollable avoidance behaviour, intrusions, nightmares, flashbacks, sleeplessness and the inability to show feelings and limitation of future perspectives. Because people with an ICD are often physically (very) ill and after multiple ICD shocks are additionally very insecure, it would seem logical if the inpatient treatment would be carried out in an institution which has close connections and is also spatially close to a cardiology department. The basis of the diagnostics is the clinical anamnesis and a systematic exploration of the trauma situation and the resulting complaints. As an additional diagnostic element psychological test procedures should be implemented to determine the core symptomatic (anxiety, depression, trauma symptoms). Psychological test procedures should be included in the diagnostics so that at the end of treatment it is obvious even to the patient which alterations have occurred. The core element of inpatient treatment is daily intensive psychotherapy and includes deep psychologically well-founded psychotherapy and behavioral therapeutic-oriented anxiety therapy as well as cognitive restructuring and elements of eye movement desensitization and reprocessing (EMDR). A follow-up examination within 4 months of the multiple shocks episode is recommended because symptoms of posttraumatic stress disorder often occur after a long latent time period.
