The pitch
Tessaly Health makes a single-use chest patch that records a medical-grade ECG, heart rate and breathing for up to 14 days after a patient leaves hospital. Its dashboard flags early signs of complications, so cardiology teams can call the patient back before an emergency readmission.
Hospitals pay a fee per monitored patient, funded from their post-operative care budgets. The patch is CE marked as a class IIa medical device and is used by 11 hospitals in Germany and Austria.
