1.1 Definition and Purpose:

An event monitor, as the name suggests, is a portable device used to monitor and record your heart’s electrical activity in response to symptoms or events you may be experiencing. It is a non-invasive diagnostic tool that helps healthcare professionals identify abnormal heart rhythms and evaluate symptoms associated with heart irregularities.

When you wear an event monitor, it continuously records your heart’s electrical activity, allowing your doctor to review the data and analyze your heart’s response during specific events or symptoms. This information provides valuable insights into your heart’s functioning and assists in making an accurate diagnosis.

1.2 Types of event monitors:

There are two main types of event monitors – symptom event monitors and memory looping monitors. – Symptom event monitors: These are typically worn for a short duration, ranging from a few days to several weeks.

They are activated by the patient when they experience symptoms such as palpitations, dizziness, or fainting spells. By pressing a button on the device, an electrocardiogram (ECG) recording is obtained, capturing the heart’s electrical activity during the episode.

This instant analysis helps doctors correlate symptoms with abnormal heart rhythms. – Memory looping monitors: These advanced event monitors continuously record the heart’s electrical activity over an extended period, usually around 30 days.

They have an internal loop of memory that saves data in a continuous loop. When a patient experiences symptoms, they can activate the device to store the preceding minutes of ECG data.

This allows doctors to analyze longer periods of heart activity and identify potential trigger factors or patterns associated with symptoms. 2) Why might I need to use an event monitor?
