Clinical Studies
We have been working with POLAR since the beginning of our startup Kardi Ai. We consider them to be a great partner that meets all requirements from a medical point of view. This fact is also supported by the two attached studies
Completed scientific studies
Polar H10 Heart Rate Sensor System
Polar Research and Technology
The authors of the work confirm the high accuracy and reliability of the Polar Pro Strap chest belt together with the Polar H10 sensor during sports activities (running, cycling and strength training). The mentioned device achieved the overall best parameters in the detection of heartbeats against comparable competitive belts, including Holter ECG monitoring.
Evaluation of the Polar H10 chest strap ECG in patients with a wide spectrum of cardiac diseases
1. Internal Clinic – Cardiology, University Hospital Olomouc
The study evaluated the original data from the Polar H10 chest belt. 161 people (54 hospitalized patients, 53 outpatients and 54 healthy people) and a total of 1,153,229 heartbeats were analyzed. When comparing the ECG waveform from the Polar H10 chest strap against a standard 12-lead ECG, the physician reliably determined the baseline heart rhythm in the majority of participants, i.e. 94.4% of inpatients and 100% of outpatients and healthy controls. It can be concluded that the ECG recording from the Polar H10 chest belt can be reliably used in daily medical practice for the assessment of the basic heart rhythm, detection of atrial fibrillation or extrasystole.
Ongoing scientific studies
KARDI AI comparison with 24-hours HolterECG in evaluation of frequent atrial and ventricular premature beats
Results by Q4/2024
Comparison of chest belt ECG analysis with ECG analysis from 24-hour HolterEKG monitoring in patients with frequent atrial and ventricular premature beats
KARDI AI comparison with 7-day HolterECG in atrial fibrillation screening
Results by Q3/2025
Comparison of the ability to detect paroxysmal atrial fibrillation from long-term intermittent chest belt ECG recording with ECG analysis from repeated, long-term Holter ECG monitoring
KARDI AI in atrial fibrillation screening after ischæmic stroke (the DEPACIS trial - Detection of Paroxysmal Atrial Fibrillation in Cryptogenic Ischemic Stroke patients using chest belt).
Results by Q3/2025
A prospective, cohort, multicenter study in subjects undergoing catheter ablation for atrial fibrillation with the FaraPulse technology. The aim of the study is to compare intermittent ECG monitoring using a Polar H10 chest belt against standard ambulatory care in the form of two 7-day Holter monitoring within 12 months after the procedure. All ECG recordings will be evaluated using artificial intelligence within the KARDI AI environment. The planned number is 200 patients, their inclusion by the end of Q3/2024 and the end of complete follow-up (a total of 12 months) by the end of Q3/2025.
Planned scientific studies
“The methodology is a huge benefit in the detection of atrial fibrillation and in the diagnosis of paroxysmal arrhythmias and irregular palpitations with a minimal chance of detection during classic ECG monitoring. The automatic evaluation allows me to have a quick overview of the patients’ “arrhythmic” situation at any time, to which I can react immediately. Thanks to the easy collaboration, the confidential relationship with the patients is also significantly strengthened.”

“I liked Kardi Ai mainly because of its quick availability in case of problems and the possibility of detecting arrhythmias that we cannot detect with commonly available monitoring. Thanks to this, we are able to quickly offer optimal treatment after consultation with the patient, but also to rule out the arrhythmogenic cause of other problems.”

“I like to use the Kardi Ai on my patients with unclear palpitations. Paroxysmal atrial fibrillation was found in 30% of them, which lead to the performance of radiofrequency ablation. I look forward to cooperation in the future and especially the possibility of detecting other forms of cardiac arrhythmias.”
