Why the study?
Does Holter PVC diurnal variability predict response to beta-blockers in patients with premature ventricular contractions?
Does Holter PVC diurnal variability predict response to beta-blockers in patients with premature ventricular contractions?
Analysis of Holter PVC diurnal variability can identify a specific subgroup (F-HR-PVC profile) that benefits from beta-blocker therapy, guiding personalized management.
F-HR-PVC profile on Holter may identify beta-blocker responders in PVC patients; hypothesis-generating and requires prospective validation before guiding therapy.
A simple analysis of Holter PVC diurnal variability may provide incremental value to guide clinical PVC management. Only patients displaying a F-HR-PVC profile benefited from beta-blockers. An alternative strategy should be considered for others, as beta-blockers may have no effect or can even be harmful.
