With the digital medical product Preventicus Heartbeats you can easily check your heart rhythm with a smartphone camera. Regular usage supports the identification of undetected heart rhythm diseases, especially atrial fibrillation, for stroke prevention. Analysis and documentation of your measurements can be performed in ECG-comparable quality. The high accuracy of the application has been confirmed in international clinical studies. With >10 million performed analyses, Preventicus Heartbeats is one of the most successful German health apps.

Regular self-measurement of the heart rhythm, especially "atrial fibrillation screening", is recommended in the guidelines of the European Society of Cardiology (ESC) and the European Heart Rhythm Association and is particularly suitable for people with an increasing risk of stroke:
- generally from the age of 65
- from 55 years of age in the presence of other cardiovascular risk factors (e.g. high blood pressure, diabetes, after a stroke or heart attack, in case of felt palpitations)
- according to doctor's recommendation

The purpose of the app is to detect evidences (suspected or tentative diagnoses) of cardiac arrhythmias, in particular
- Extremely irregular pulse (absolute arrhythmia) with suspected atrial fibrillation
- Suspected other cardiac arrhythmias with frequent irregular heartbeats (e.g. ectopic heartbeats)
- Determination of the heart rate with indications or suspicion of bradycardia (pulse too low) or tachycardia (pulse too high), without their further diagnostic differentiation

All results are suspected (tentative) diagnoses of a digital medical device, not an actual diagnosis in the medical sense. Suspected (tentative) diagnoses are under no circumstances a substitute for personal consultation, diagnosis or treatment by a physician. This app may not be used to make decisions in situations that are considered life-threatening.

A major risk factor for stroke is untreated atrial fibrillation (AF). It is often unnoticeable and only occurs occasionally, making it difficult to detect in a doctor's office. Therefore, guidelines recommend regular self-checking of the heart rhythm. After medical diagnosis of AF, a (mostly drug-based) therapy can almost normalize the risk of stroke.

Use the free basic version to get to know the measuring process, determine your heart rate and get first hints if the app detects possible heart rhythm disturbances. The full version offers you additional features:
- a detailed analysis and presentation of the measurement results in ECG comparable manner
- saving and sharing measurements as an ECG-comparable PDF document
- a longer 5-minute measurement option, especially if recommended by a doctor, in order to be able to record less frequent arrhythmic events more probably
- optionally the possibility for ECG technicians of Telecare centers to perform an evaluation of the measurements to exclude possible measurement errors and to verify rhythm disturbances from a medical-technical point of view. Use this possibility especially after a doctor's recommendation, since a medical-technical pre-qualification of your measurements can considerably support the subsequent diagnostics of your doctor

Very helpful app

As with any app claims, I was sceptical, but I started having what I describe as chest flutters and this app accurately recorded it. I sent a copy to both my GP and cardiologist to show what I’ve been experiencing. As a result, a 2 week monitor was ordered. I didn’t rate as five stars because I think the app needs more choices or an additional field regarding activity at the time of symptoms e.g. exercising, eating, resting, etc. As someone not as familiar with different types of irregular beats, it would be nice to have a more detailed description of what each type of beat means.

Very helpful

I’ve had this app for about a year and have found it incredibly reassuring and helpful. I have a family history of heart issues and I get a lot of chest discomfort from GERD so whenever I feel something funny in my chest my anxiety shoots up making the problem worse. This app has been a very helpful tool as a quick prescreening device. I’ve even used it with my Mom and sister-in-law. I like that it doesn’t require any additional attachments so I can check my heart quickly anywhere anytime I’m feeling concerned.

Has worked great up until today

Love this app as it gives me piece of mind that I’m in a normal sinus rhythm; however, not sure if there’s an issue with their server, but all day it has given me an error that it’s having problems communicating with the server. It’s not my internet and I tried it at work as well. Hope it gets fixed soon!

Developer Response ,

Thank you for your feedback. We had a short server failure. We were able to identify and correct the error already. The app should work properly again. We apologize for the inconvenience and thank you for your understanding. Your Preventicus team
