Conclusion: Telemonitoring practices of patients with ICDs involve three entangled collaborative processes, whereas the existing socio-technical setup only mediate one. myRecord is designed as an add-on collaborative technology to mediate the two remaining collaborative processes. We argue that myRecord solves some of the problems with ICD data interpretation inherent in telemonitoring practices by providing a collaborative, asynchronous space for healthcare practitioners and patients to mediate the two processes that are otherwise lost. Our new socio-technical design also transforms the role of patients considerably, thus new studies should take these insights into consideration.
