Heart Rhythm Monitors

Heart Rhythm Monitors come in two different types: Holter Monitors and Event Monitors.

Holter Monitors

A Holter monitor is a portable device worn continuously for 24 hours. This is helpful in observing for occasional arrhythmias (abnormal heart rhythms) that would be difficult to identify on an EKG.

Event Monitors

Event monitors are 15-day medical devices that record the heart’s electrical activity. Doctors most often use these monitors to diagnose arrhythmias. Event monitors require patient activation to record heart rhythms.


There is no preparation necessary prior to this appointment.


It will take approximately 20 minutes to apply the Holter monitor in our office. A follow-up visit will be scheduled 10-14 working days after the test for a provider to go over the results.
