Implantable Loop recorder
Implantable Loop recorder (Reveal) can help in establishing whether symptoms such as dizziness, blackouts and palpitations have a cardiac cause. Syncope, or blackout, is often difficult to diagnose as episodes are often too infrequent and unpredictable. Unlike conventional ECG monitoring (such as 24-hour ECG monitor or event monitors), loop recorder monitors heart rhythm continuously for up to two years, so that the likelihood of capturing ECG during the episode is greatly increased. To store the heart rhythm, also known as ECG, a patient needs to place a special activator over the implanted recorder and press a button. The device also can store rhythms automatically when patients are unable to use the activator or when patients are asymptomatic.
