The holter monitor is a device you wear attached to your chest with five EKG leads. The device is worn on a belt around your waist. The device records the electrical activity of the heart for 24 hours. The doctor then analyzes the electrical activity and rhythm of your heart to find out if you have any heart arrhythmias.
The day of your appointment do not wear any lotion on the chest area. The area may need to be shaved on male patients. The monitor cannot get wet. You will not be able to shower or bathe for 24 hours after the monitor is applied.
