Arrhythmia is defined an abnormality in the heart transmission system related to heartbeat or heart rhythm problem (Li et al., 2017). Most of arrhythmia could diagnosed and treated effectively, including medication, cardiac implantable electronic device (CIED) and operation. Many patients have uncertainty about the implantation process, the results and possible complications after CIED, the lack of understanding about further progress of their disease, the change of lifestyle and the accident of electronic shock. Those causes are the physical and mental negative impacts on patient which makes anxiety or depressed and turn affects the quality of life.~At present, there are few clinical models for CIED utilizing electronic multi-media in Taiwan. The use of multi-media models may integrate clinical care and health education for helping patients to learn disease and care, also through vivid video and multi-media, we may make a clear education of disease causes, treatment and relevant care knowledges which are alleviate the uncertainty factors from patients (Hsueh et al., 2016). Therefore, the more overall understanding before CIED intervention, the more helpful to quality of living and psychological adjustment of the patient.~In this study, we aim to design a multi-media model through e-book for preoperative care of CIED intervention, which can enhance the knowledges of patients, reducing the stresses and uncertainties before the intervention. Therefore, patient may reduce the psychological internalization after CIED intervention, also needs to track the impact of emotional depression, psychological adaption and life quality status.~keywords：Cardiac Implantable Electronic Device、arrhythmia、electronic multimedia、quality of life、psychological adjustment、depression
