A loop monitor is used to evaluate the heart rhythm during infrequent
transient symptoms.
The heart normally contracts regularly due to an orderly spread of
electrical activity from an area of specialized heart cells called
”pacemaker cells” to the rest of the heart. An electrocardiogram (ECG)
represents a surface mapping of the electrical activity of the heart.
There is a normal pattern of changes in the electrical activity of the heart
with activities such as exercise. Normal variations in electrical activity
occur with various activities. With different types of heart disease, there
will be various other patterns of changes in the electrical activity of the
heart during normal daily activity. The resulting changes in the rate and
shape of the surface mapping of the electrical activity during normal daily
activity are continuously monitored by the loop monitor.
