Holter heart monitor

Ambulatory electrocardiography; Electrocardiography - ambulatory

Normal variations in heart rate occur with activities. A normal result is no significant changes in heart rhythms or pattern.

Abnormal results may include various arrhythmias. Changes may mean that the heart is not getting enough oxygen.

The monitor may also detect conduction block, a condition in which the atrial electrical activity is either delayed or does not continue into the ventricles of the heart.
