Your next bathroom break could come with an unexpected bonus: a check of your heart rhythm. German medical technology company Hamberger Medical has developed the HARO EKG-seat. It looks like a regular toilet seat, but built-in sensors record an electrocardiogram, also called an EKG or ECG, while you sit.
After about 30 seconds, a connected smartphone app analyzes the reading for signs of an irregular heart rhythm, including possible atrial fibrillation. AFib is the most common type of irregular heartbeat, and millions of people may have it without realizing anything feels wrong. It sounds like the kind of idea someone dreamed up during a very long bathroom break.
However, the possibility of catching a silent heart condition during something you already do every day deserves attention. Here’s what the early research reveals about how well the seat works and where its limits begin.

COULD A PAINT-ON ELECTRONIC TATTOO SPOT HEART ATTACKS?
How the smart toilet seat checks your heart
A conventional medical EKG usually requires you to lie down while a medical professional places electrodes on your chest and other parts of your body. The HARO EKG-seat takes a different approach. Its sensors collect electrical signals from your body while you sit normally. The seat records a six-lead resting EKG and sends the information to its companion app through Bluetooth.
You do not need to attach sticky pads or remember to put on a wearable. You sit for about 30 seconds and let the seat do the work. Hamberger Medical says participants in its usability testing could operate the system without special instructions. The oldest participants in one reported study were in their 90s, according to published reports about the device. That simplicity may become one of its biggest strengths. Many health devices end up forgotten in a drawer after the novelty fades. A toilet seat is harder to forget.
Smart toilet seat study shows promising AFib results
The company tested the seat through what it calls the Hamberger Heart Study. Researchers compared the seat’s six-lead EKG with a standard 12-lead medical EKG. Hamberger Medical reported a high level of agreement between the two systems when checking for AFib and other rhythm abnormalities.
That sounds encouraging, but there is an important limitation. The complete results have not been published in an independently peer-reviewed medical journal. Public reports also do not provide enough detail about the study’s size, false alerts or performance across different groups.
Without those numbers, we cannot tell how often the seat might miss AFib or mistakenly warn someone whose heart rhythm is normal. For now, the results should be viewed as promising company-reported findings. They do not prove that the seat can replace a hospital EKG or a doctor’s diagnosis.
Why AFib can be difficult to catch
AFib causes the heart’s upper chambers to beat irregularly. Blood may then pool inside the heart, which can allow clots to form. A clot can travel to the brain and cause a stroke. The American Heart Association says AFib is linked to about five times the risk of stroke. Some people feel a racing heartbeat or fluttering in their chest. Others notice fatigue, dizziness or shortness of breath.
However, AFib can also arrive without obvious warning signs. A person may feel fine while the irregular rhythm comes and goes. That creates a detection problem. A brief EKG at a doctor’s office may look normal if the AFib episode ended before the appointment. Doctors sometimes use longer-term monitors when they suspect an intermittent rhythm problem. A toilet seat that records readings regularly could provide more chances to capture an episode.
WEARABLE PATCH VIBRATES WHEN DANGER IS NEARBY
Early AFib detection could help prevent serious problems
The American Heart Association estimates that about 5 million Americans currently live with AFib. It projects that more than 12 million could have the condition by 2030. Early detection can help doctors decide whether someone needs medication, additional monitoring or treatment to restore a normal rhythm.
Dr. Paari Dominic, a cardiac electrophysiologist, told the American Medical Association that earlier intervention can significantly improve outcomes. He noted that research supports pursuing normal rhythm within a year of detecting AFib in appropriate patients. However, a notification from a toilet seat should begin a medical conversation. It should never end one.
Who faces a higher risk of AFib?
Age raises the likelihood of developing AFib. High blood pressure also plays a major role. Diabetes, obesity, sleep apnea and certain heart conditions can increase the risk. Smoking and excessive alcohol use may contribute as well.
Heavy drinking can sometimes trigger an irregular heartbeat even in people without a known heart condition. Doctors often call this “holiday heart syndrome” because cases can rise during celebrations involving heavier alcohol use. People who already face a higher risk could benefit most from convenient monitoring. That decision should involve a cardiologist or another qualified medical professional.
How the smart toilet seat handles health data
A heart-monitoring toilet seat collects highly sensitive information, so its privacy protections deserve a close look. According to Hamberger Medical’s app privacy policy, EKG processing happens locally on the connected phone or tablet. The company says readings are not sent to its servers. The app also lets you export a PDF report. Hamberger Medical recommends protecting the file with a password before sending it to someone else. However, your phone’s backup settings may still upload app information to iCloud or Google Backup. The company notes that this depends on how you configured your device.
Before using any connected health product, check its backup settings and sharing options. You should also protect your phone with a strong passcode. For additional steps, see our guide on how to stop health and fitness apps from using your private data.

Is the HARO EKG-seat available to buy?
The HARO EKG-seat does not currently appear to be available for purchase. Hamberger Medical previously said the device was sold exclusively through its official German online shop at approximately $2,870. CyberGuy reached out to Hamberger Medical to confirm current availability, pricing and whether the company plans to sell the EKG-seat in the United States, but did not hear back before our deadline.
What this means to you
The HARO EKG-seat shows how health monitoring could blend into your normal routine. That part is genuinely promising. The clinical report suggests the seat can record EKGs that cardiologists interpret with strong accuracy. However, the current app results do not support relying on its automated AFib classification alone.
A normal app reading should not convince you to ignore symptoms. An abnormal warning should lead to a conversation with a medical professional. Contact your doctor if you notice a racing or irregular heartbeat, recurring dizziness or unexplained shortness of breath. Chest pain or pressure may signal a medical emergency, so call 911 right away. Never start or stop heart medication because of a consumer device result. Your doctor may order a clinical EKG or longer-term monitoring before making a diagnosis.
Kurt’s key takeaways
There is something undeniably clever about turning an ordinary toilet seat into a heart monitor. It fits health screening into a routine that people already follow without reminders. The company-reported results sound encouraging, especially for a condition that may hide between doctor visits. Smart health technology works best when it helps you notice a concern sooner and gives your doctor useful information. It becomes dangerous when a gadget creates false confidence or replaces professional care.
