Kardi Ai, a pioneering health technology company founded in 2022 and headquartered in Olomouc, Czech Republic, is revolutionizing cardiovascular monitoring. Its innovative solution combines a comfortable chest strap ECG recording device with a cutting-edge application certified as a Class IIa medical device. This advanced system continuously monitors heart rhythms, instantly detecting irregularities and alerting users in real time. It also generates detailed reports, empowering physicians with precise diagnostics.
By harnessing artificial intelligence, Kardi Ai delivers unlimited, real-time ECG measurements, significantly improving early detection and proactive management of heart conditions. Committed to making heart health accessible, the company strives to empower individuals with affordable, AI-driven monitoring solutions that put control directly in their hands.
At Medical Fair India 2025, The Interview World engaged in an exclusive conversation with Vlastimil Hrabal, CEO of Kardi Ai. He delved into the role of wearable technology in preventing cardiovascular diseases, emphasizing the unparalleled accuracy of the device, its affordability, and the vast market potential for such innovations. He also highlighted the stringent safety standards Kardi Ai upholds. Here are the key insights from this compelling discussion.
Q: Can you share insights into the design and functionality of your wearable device for preventing cardiovascular diseases? How does it monitor and mitigate potential risks?
A: Our product seamlessly integrates hardware and software to deliver real-time heart monitoring. Simply wear the belt and launch our app, which continuously tracks your ECG and detects heart arrhythmias. These irregularities are critical—left unaddressed, they can lead to strokes, heart attacks, or early-onset dementia. In India alone, 8,000 people die daily from these conditions.
This is a massive health crisis. With our solution, you can monitor your live ECG instantly. Removing the belt alters the ECG in real time, demonstrating its accuracy. After each measurement, the system evaluates your heart’s condition within five minutes. A green light signals normal function. Yellow indicates non-life-threatening arrhythmias. Dark orange means you need to see a cardiologist immediately.
For every measurement, you can download a certified medical report. Our device is EU-certified and trusted by over 150 cardiologists—representing 15% of the market in the Czech Republic—and is actively used in 20+ hospitals. Designed with expert insight, one of our co-founders is a professor of cardiology.
With over five times the detection rate of the standard Holter 24-hour ECG, our device offers unparalleled accuracy. Unlike Holter monitors, which must be returned after 24 hours, our product is yours to use anytime, anywhere. Wear it while sleeping, showering, or running—its signal remains stable and clear, even with movement.
Advanced AI evaluates your heart’s performance and provides instant feedback, empowering you to take preventive action. Early detection is crucial—identifying heart damage in its initial stages can be life-saving.
Q: How accurate are your findings of the wearable device, and what measures have you taken to validate them?
A: The ECG recorded from this belt delivers a 99% match to a hospital-grade 12-lead ECG, as validated by clinical studies. Its sensitivity stands at 90%, meaning it accurately detects arrhythmias in 90% of cases. While we could push sensitivity even higher, doing so would also raise the risk of false positives—something we consciously avoid to prevent unnecessary alarm. At 90%, the sensitivity strikes the optimal balance, a level officially certified and clinically confirmed as sufficient.
Q: How cost-effective are these belts for patients in India?
A: A week-long Holter monitor test in India typically costs ₹13,000 to ₹14,000, based on hospital feedback. In contrast, this product offers an entire year of continuous monitoring for around ₹20,000. That translates to less than ₹2,000 per month.
With full ownership of the belt, you can use it anytime symptoms arise—an essential advantage since 60% of patients experience noticeable symptoms. In just two seconds, you can wear it like a bra, start measuring, and instantly share results with your doctor.
Compared to existing options in India, this solution is significantly more affordable. More importantly, it is the only device capable of monitoring your heart for extended periods—three, six, or even twelve months—ensuring long-term cardiac health tracking.
Q: What are your insights on the market opportunities in India, and how do you see the demand evolving in the coming years?
A: You don’t need to wear this device 24/7. Just two to three hours every other day is enough. Despite this limited usage, it delivers five to six times higher detection rates than any other solution worldwide.
India faces a severe cardiovascular crisis. Every day, 8,000 people die from heart-related diseases. In general, 30-40% of the population suffers from cardiovascular issues. With India’s 1.2 billion people, that translates to a staggering market of 500-600 million individuals at risk.
This issue demands urgent attention. Our solution doesn’t just detect problems early—it actively prevents life-threatening events. Prevention isn’t just life-saving; it’s also economically smarter. Treating a heart attack or stroke is far costlier than preventing one. The potential impact in India is immense.
Q: Given that this belt utilizes electromagnetic interactions with heart pulses, how do you assess its long-term safety and health implications for users?
A: This fitness belt is designed for optimal health. It features a single-lead ECG that accurately measures your heart’s electrical signals. As an ECG device, it poses no risk to your health—only benefits. It actively helps prevent cardiovascular issues and supports overall heart wellness.
