Exercise-Induced Ventricular Arrhythmias (EIVA) may be encountered during or after exercise. These are important to identify since their occurrence is associated with increased mortality.


Criteria for EIVA - occurrence during exercise or recovery of one or both of the following:

(1) run of >= 3 consecutive premature ventricular contractions (PVCs) at any time

(2) PVCs constituting > 10% of all ventricular depolarizations during any 30 seconds


PVCs as percent of all ventricular depoalrizations =

= (number of PVCs during a 30 second recording) / (total number of ventricular depolarizations during a 30 second recording) * 100%


EIVAs are associated with:

(1) older age

(2) cardiopulmonary disease

(3) exercise-induced ischemia

(4) resting PVCs


A patient with EIVA is a candidate for interventions to prevent cardiovascular disease.
