Did you know?

Cardiac rhythm disorders, primarily undetected atrial fibrillation, are associated with a highly elevated risk of stroke. Atrial fibrillation often goes unnoticed, only occurs with sporadic frequency and therefore sometimes defies medical diagnosis.

Once atrial fibrillation is detected, medicines can markedly lower and almost normalize the danger of clot formation and the stroke risk.

Detect atrial fibrillation

Atrial fibrillation causes your heart to beat irregularly, which also leads to irregular blood flow.

Atrial fibrillation undetected

This and other pathophysiological mechanisms can cause dangerous blood clots to form.

Atrial fibrillation heart attack

Blood clots that migrate from the heart to the brain can cause a stroke.

Every life beats to its own rhythm.

Many people do not notice their cardiac rhythm disorders, others are anxious and unsettled by their noticeable palpations. An irregular cardiac rhythm may indeed be harmless, but is just as often critical, especially because those affected find it difficult to make clear-cut distinctions where the boundaries are sometimes blurred. If atrial fibrillation goes undetected and untreated, it can pose a significant risk for stroke.

Moreover, cardiac rhythm disorders often occur sporadically. That is why they are not always detected in the doctor's examining room or on a 24-hour ECG. Conventional 24-hour ECG only detects sporadic atrial fibrillation in around 20 percent of all patients.2 To maintain a greater degree of certainty and your peace of mind, you can personally begin taking regular recordings of your cardiac rhythm, thereby optimally adding value to the diagnostic options available to your physician.

Detect and conquer

If atrial fibrillation is detected and later confirmed by your doctor by ECG, your stroke risk can be reduced or normalized with medication. What is decisive is the regular use of Preventicus Heartbeats: twice daily over a period of at least 14 days or every two days for one quarter as well as whenever you notice heart palpitations.

Studies on small ECG devices for self-monitoring have shown that a comparable measuring procedure can detect a greater number of episodes of arrhythmia and atrial fibrillation than a 24-hour Holter ECG. 3,4

This is what your PDF report tells you.

From the pulse curves, its algorithm precisely calculates the clustered occurrence of extra beats and/or the presence of absolute arrhythmia suggesting a suspicion of atrial fibrillation.

When more than 5% of all beats are extra beats, the Preventicus Heartbeats app signals the suspicion of mild cardiac arrhythmia with a yellow traffic light. The red traffic light appears if there is a suspicion of significant cardiac arrhythmia (presence of absolute arrhythmia suspicious of atrial fibrillation). The app also gives you supplemental information about any relevant pulse rates that are consistently too low (bradycardia) or too high (tachycardia). Any interferences occurring during the measurement (wobbling, coughing, shaking, etc.) are detected and eliminated fully automatically.

The full version of the Preventicus Heartbeats app additionally generates a PDF report which depicts the original five-minute pulse curve recordings and R waves symbolic for each cardiac cycle. This allows your physician to trace the automatic interpretation and visually evaluate your cardiac rhythm.

As clinical studies have demonstrated, the app's algorithm can distinguish normal cardiac rhythm from cardiac rhythm disorders (like atrial fibrillation) with an accuracy of up to 95 percent.
This means that the Preventicus Heartbeats app missed a cardiac rhythm disorder although present and/or classified a normal cardiac rhythm as a rhythm disorder, although it was not, in merely 5 percent of all cases. Users of this app are aware of this minor possibility of such a misinterpretation. Users hereby release Preventicus GmbH from any liability arising from such misinterpretations.
