Prognostic significance of ambulatory ECG monitoring for ventricular arrhythmias.

Ventricular arrhythmia can be detected in ambulatory ECG monitoring in individuals with or without cardiac disease, and its prognostic value varies, depending on the underlying condition. The use of continuous or intermittent ambulatory ECG monitoring can be helpful for diagnosis when there is a high pre-test probability of identifying a transient arrhythmia. In addition, Holter monitoring can be used for risk stratification of patients, in the context of the prognostic value of non-sustained ventricular arrhythmias in various clinical settings, as discussed in detail.
