anxiety
In this study, heart rate and rhythm recordings were collected for 4 weeks by the patients via intermittent monitoring using an ECG‐based handheld mHealth device. Although beneficial in terms of accessibility and patient convenience, it does not supply continuous data, and the best time points and frequency of recordings to optimally use such a monitoring approach in this specific clinical scenario remains unclear. In addition, the short‐term follow‐up period of 4 weeks only limits transferability to long‐term results. We did not apply any anxiety‐specific questionnaires and can therefore not confirm whether the positive effect of a delayed cardioversion approach can indeed partly be attributed to reduced anxiety and the development of better coping mechanisms in these patients. Drug titration was found to be suboptimal in many cases, given the fact that rate control therapy was (at least partly) inadequate in 73.5% of patients. Irrespective of randomization group, more adequate drug titration should be pursued. Lastly, some subgroup analysis should be interpreted with caution, given the sample size.
