KARDI AI Technologies s.r.o

KARDI AI Technologies s.r.o. is a Czech med-tech company developing Kardi Ai, an AI-powered solution for long-term remote ECG monitoring and the early detection of cardiac arrhythmias.

Kardi Ai is an MDR Class IIa certified medical device that combines a wearable ECG sensor, mobile application, physician portal and artificial intelligence. It enables continuous, non-invasive ECG monitoring for up to 12 months. AI automatically analyses ECG recordings within minutes, detects cardiac arrhythmias and provides physicians with long-term heart rhythm trends to support earlier diagnosis and treatment.

The solution addresses a major limitation of current cardiac diagnostics: standard ECG and Holter monitoring capture only a short period of heart activity, while arrhythmias may occur unpredictably over days, weeks or months. Long-term monitoring therefore significantly increases the probability of detecting intermittent arrhythmias and can help prevent serious complications such as stroke, heart failure and early onset of dementia.

Kardi Ai has achieved 6–10× higher arrhythmia detection compared with 24-hour Holter ECG, with 93.3% AI accuracy and 97.8% specificity. The solution has more than 5,700 registered users, has analysed over 350,000 ECG recordings and 3 billion heartbeats, and is used by more than 180 cardiologists and 60 hospitals and healthcare providers across five European countries.
