Why the study?
Whether heart rate variability relates to arrhythmia burden remains uncertain in unselected implantable cardiac monitor populations.
Does heart rate variability relate to arrhythmia burden (PVC and AT/AF) in unselected patients with implantable cardiac monitors?
Observational

Answers are grounded in this paper and cite their sources.
Evaluates heart rate variability patterns across arrhythmia strata via implantable cardiac monitors, highlighting links between autonomic balance and arrhythmic burden.
Heart rate variability reflects beat-to-beat variation in cardiac timing and is widely used as a non-invasive marker of autonomic balance. Reduced HRV has been linked to arrhythmia susceptibility and adverse cardiovascular outcomes. Implantable cardiac monitors permit longitudinal HRV assessment alongside PVC and atrial tachyarrhythmia (AT/AF) burden from remotely transmitted trend reports. Whether HRV relates to arrhythmia burden remains uncertain in unselected ICM populations.
