Key result
Extended 14-day ambulatory ECG monitoring nearly doubled the identification of patients reaching a 10% premature ventricular contraction burden threshold compared to 24 hours of monitoring.
Why the study?
Does 14-day extended ambulatory ECG monitoring improve the identification of clinically significant PVC burden compared to 24-hour monitoring?

Does 14-day extended ambulatory ECG monitoring improve the identification of clinically significant PVC burden compared to 24-hour monitoring?
Extended 14-day ambulatory ECG monitoring captures significant day-to-day variability in PVC burden and substantially increases the detection of clinically significant ectopy compared to standard 24-hour monitoring.
No takes yet. Share an insight, caveat, or question.
May support extended monitoring for PVC assessment; leaves open effects on management and outcomes.
Loring et al. (2016) conducted an observational in Premature ventricular contractions (PVCs) (n=101). Extended (14-day) ambulatory ECG monitoring vs. 24-hour ambulatory ECG monitoring was evaluated on Time to cross clinically significant PVC thresholds (≥10%, 15%, or 20% of total heartbeats). Extended 14-day ambulatory ECG monitoring nearly doubled the identification of patients reaching a 10% premature ventricular contraction burden threshold compared to 24 hours of monitoring.
