Why the study?

Does 24-hour electrocardiographic monitoring of spontaneous heart rate dependency predict the behavior of premature ventricular contractions during exercise in patients with frequent PVCs?

Population

126 patients with frequent (> 30/h) premature ventricular contractions, mean age 49 +/- 16 years.

Design

Cross-sectional

Implication

Tachycardia-enhanced Holter pattern may predict exercise PVC increase; leaves open prospective validation before guiding testing in frequent PVCs.

Structured PICO

Does 24-hour electrocardiographic monitoring of spontaneous heart rate dependency predict the behavior of premature ventricular contractions during exercise in patients with frequent PVCs?

P
Population
126 patients with frequent (> 30/h) premature ventricular contractions, mean age 49 +/- 16 years.
I
Intervention
24-hour electrocardiographic monitoring to assess spontaneous heart rate dependency of premature ventricular contractions, followed by an exercise test.
O
Outcome
Behavior of premature ventricular contractions during exercise (change in number of PVCs/min at maximal effort compared to baseline).surrogate

Analysis of spontaneous heart rate dependency of premature ventricular contractions on 24-hour Holter monitoring can predict their behavior during exercise testing.
