Holter 24-hour monitors are useful in quantifying and characterizing ventricular ectopy. Holters also have been used to determine treatment efficacy in patients with frequent or complex PVCs. Suppression of ectopy on Holter monitoring is not always predictive of survival. The most important role for Holter monitoring is risk stratification of patients with a recent myocardial infarction (MI) or known left ventricular dysfunction. More than 60% of healthy, middle-aged men have ventricular ectopy on Holter monitoring.
