What is ambulatory rhythm monitoring?
Ambulatory rhythm monitoring uses a small portable electrocardiograph device to measure the electrical activity of your heart for an extended period of time.
How does ambulatory rhythm monitoring work?
The heart has its own electrical system that synchronizes the heart to contract in rhythm and pump blood. Every heartbeat creates a pattern of electrical activity that can be detected with an electrocardiogram device. Like an electrocardiogram in the clinic, the most common types of ambulatory rhythm monitoring use external leads (small patches that are attached to the skin) to record the electrical activity of the heart. More advanced ambulatory rhythm monitoring equipment may be implanted under the skin for long-term recording.
When ambulatory rhythm monitoring is prescribed, the patient is outfitted with a portable electrocardiograph device in the clinic and asked to keep a diary of certain activities while they are being monitored. This helps cardiologists connect symptoms and abnormal sensations to electrical abnormalities in the heart.
Types of ambulatory rhythm monitoring
There are different types of ambulatory rhythm monitoring that are used for specific heart conditions. Generally, different types of ambulatory rhythm monitoring can be described as either continuous monitoring, event monitoring, or loop recording.
Continuous Monitoring
There are different types of ambulatory rhythm monitoring that are used for specific heart conditions. Generally, different types of ambulatory rhythm monitoring can be described as either continuous monitoring, event monitoring, or loop recording.
Event Monitoring (External Loop Recorders)
Like continuous monitoring, event monitoring uses an external portable electrocardiograph device, but only records the heart’s electrical activity when activated. Some devices activate automatically when they detect slow, fast, or irregular heart rates; other devices must be activated by the patient during a symptomatic event. When activated, data is either stored for later review or transmitted to a cardiologist.
Implantable Loop Recorders
An implantable loop recorder is a small device that is implanted in the chest just under the skin that records the electrical activity of the heart when activated. Depending on the device, it may be activated automatically when the device detects an irregular heart rate, or activated by the patient during a symptomatic event by placing an activator over the device.
