Irregular Rhythm Notification

Passive background monitoring that alerts users to irregular heart rhythm patterns beyond atrial fibrillation. Using continuous PPG or periodic ECG sampling, algorithms detect rhythm irregularities including frequent premature atrial contractions (PACs), premature ventricular contractions (PVCs), and other arrhythmias. Irregular rhythm notifications differ from AFib detection in detecting broader abnormality categories without specific diagnosis. Occasional irregular beats are normal and increase with age, caffeine, stress, and dehydration; notifications indicate patterns exceeding normal thresholds. FDA-cleared irregular rhythm features must demonstrate appropriate sensitivity and specificity to avoid excessive false alarms while catching clinically significant arrhythmias. Users receiving notifications should consult healthcare providers for proper evaluation, which may include Holter monitoring or event recorders. These notifications have identified previously undiagnosed arrhythmias leading to appropriate treatment, though they can also cause anxiety from benign findings.
