Some facts about Loop Recorder Implantation:

  • The machine works as an electrocardiogram (ECG) by continuously picking up electrical signal from your heart which can help find abnormal heart rhythms that can cause a number of problems such as fainting.
  • A loop recorder implantation is required if you have fainting episodes or palpitations, and other tests have not yet given you any answers, since repeated fainting can have a negative effect on your physical and emotional health.
  • A pacemaker or an implantable cardioverter-defibrillator (ICDs) is required once these fainting episodes are diagnosed.
  • A loop recorder is also required if your healthcare provider wants to look for very fast or slow heartbeats as these abnormal heartbeats can cause palpitations, or even lead to strokes.
  • All loop recorders generally come programmed to record certain fast and slow heart rates.
