Regular heart rhythm: Indicates a detected regular rhythm. Increased heart rhythm variability: Signifies a higher variability in heart rate, common in younger and physically active individuals, indicating a healthy heart response. Extrasystoles (isolated or frequent): Refers to extra heartbeats originating from the heart's upper or lower chambers, often harmless but could indicate more serious conditions if frequent. Tachycardia (episode): A faster-than-normal heart rate which might require medical attention. Bradycardia (episode): A slower-than-normal heart rate, normal for some but potentially serious if symptomatic. Dubious rhythm: Unclear results that suggest potential underlying rhythm disorders, necessitating further analysis. Atrial fibrillation or flutter: An irregular heart rhythm that could indicate atrial fibrillation, associated with a higher stroke risk, advising consultation with a medical professional.
