Loop Recorder (King of Hearts)

Objectifs 

A loop recorder (a portable event recorder) is a non-invasive exam (i.e., it does not require opening the patient) that is used to record heartbeats while the patient experiences symptoms (palpitations, breathlessness, dizziness, fainting) and/or to detect arrhythmia based on the parameters set in the recorder. Two electrodes are attached to the chest and worn at all times, and the patient must change these electrodes every day. 

Duration 

2 weeks.

Preparation 

The loop recorder is given to the patient at a visit to the ambulatory clinic.

For this visit:

  • Bring a full and updated list of medications
  • Avoid applying body lotion before the exam 
Steps 

During the appointment, a technologist will give instructions for the next two weeks. The technologist will also perform a test to ensure that the patient clearly understands the instructions and knows how the device works. Extra electrodes are provided so that they can be changed. The patient must bring the device back on the date indicated by the technologist.

The device must not get wet (in the pool, bath or shower), and patients must continue with their normal daily activities. 

Follow-up and side effects 

A cardiologist analyzes the events recorded over the two-week period and then sends the results to the requesting physician.
