Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators want to investigate if a continuous heart rate monitoring with a wrist worn fitnesstracker can be useful in the treatment and surveillance of patients suffering from Graves' disease.The aim of our research project is two-fold: First, to evaluate the use of continuous heart rate monitoring as a potential substitute for hormone measurements during treatment of hyperthyroidism. Second, to use continuous heart rate monitoring as a tool for early detection of relapse after discontinuation of antithyroid drugs.
