Ambulatory monitors are small, portable electrocardiograph machines that are used to help doctors diagnose intermittent cardiac arrhythmias that occur only infrequently and unpredictably. Such arrhythmias often produce sudden symptoms, but typically are no longer present by the time a person gets to a doctor. For this reason, many symptom-producing cardiac arrhythmias are difficult or impossible to diagnose with a standard electrocardiogram. Each type of monitor has unique features related to the length of recording time and the ability to send the recordings over the phone.
Ambulatory monitoring is used to;
- Assess your heart rhythm over time
- Correlate your symptoms with your heart rhythm
- Diagnose abnormal heart rhythms: what kind they are, how long they last, and what may cause them
- Guide treatment for abnormal heart rhythms
Types of Ambulatory Monitors
Several different types of ambulatory ECG monitoring include Holter monitors, event monitors, patch monitors, and implantable monitors.
- Holter Monitors
The Holter monitor is worn continuously for a fixed, relatively short, period (usually for 24 or 48 hours), and records every heartbeat during that time. The recorder is then analyzed to look for any cardiac arrhythmias that may have occurred during the recording period.
- Event Monitors
Event monitors are a family of devices that (generally) do not attempt to record every heartbeat over a prolonged period, but rather, attempt to capture specific episodes of cardiac arrhythmia. They are used to capture an ECG at the time intermittent symptoms occur, even if those symptoms are quite infrequent.
- Patch Monitors
A patch monitor stores all a person’s heartbeats during that time and employs arrhythmia detectors that can transmit an ECG wirelessly if a cardiac arrhythmia occurs. The two most commonly used patch monitors are the Zio patch (iRhythm) and the SEEQ patch (Medtronic).
- Implantable Monitors
Implantable monitors (often referred to as implantable loop recorders) are ECG recording devices that are “injected” under the skin (with local anaesthesia), and that remain functional for up to a few years. They continuously record the heart rhythm.
Implantable ECG monitoring devices are reserved for people who have extremely infrequent symptoms that are strongly suspected to be due to potentially dangerous cardiac arrhythmias. They have mainly been helpful in the diagnosis of syncope of unknown origin. They are also very helpful in the setting of someone who has had a stroke thought to possibly be secondary to an arrhythmia.
