Heart failure case study: telemonitoring prevents cardiac decompensation
A concrete case from a cardiological group practice in Krefeld shows how telemonitoring of important vital signs and direct communication with patients can help to identify and treat critical events at an early stage.

The threat of cardiac decompensation could be averted at an early stage by adjusting the medication.
In our practice, cardiac decompensations have already been prevented in several cases by telemonitoring without the need for a visit to the practice. Of course, our patients think this is great and it saves us an immense amount of time in our practice!
