Telemonitoring is used to monitor implantable cardioverter defibrillators (ICDs). Despite the scientifically proven effectiveness and safety of telemetric care, studies show that the offer is not used and accepted by all patients.The aim of this study is to investigate the attitudes of ICD patients towards telemonitoring, including which aspects influence attitudes and decision-making.Data were collected using semi-structured, guideline-based individual interviews. A total of 14 patients with a subcutaneous ICD (sICD) and both primary and secondary prophylactic indications were recruited. Data analysis followed a content-structuring qualitative approach.Patients with telemonitoring perceived a high benefit with low concerns about digital technology, while the opposite was observed for patients without telemonitoring. The patients' previous medical experience has a crucial impact on the acceptance of telemonitoring. All age groups reported the technical implementation and practical handling of telemonitoring to be simple and uncomplicated.The results suggest that the primary and secondary prophylactic indication for ICD implantation have an influence on the attitude towards telemonitoring and, thus, on acceptance. Further qualitative research regarding user acceptance of telemonitoring of other ICD systems is needed.
