The ILR has the ability to record the electrical activity of the heart in two ways.
Your doctor will set a range of expected heart rhythms, and if the heart rate drops below the lowest value set by your doctor, the ILR will automatically start to record. In the same way, if the heart rate rises over the highest value set, the ILR will also record without the patient’s knowledge.
The second way it records is through a patient activator whereby you can trigger a recording by pushing a button on the activator. The activator can be used when you experience symptoms such as skipped beats, light-headedness, or dizziness. To start a recording, simply place the patient activator over the ILR and press the button. A green light will flash when recording is successful.
The recording is stored in the ILR. Your physician can view both the automatic and triggered events during a routine office visit using a special programmer.
