Which leads are recorded on Holter monitor?
The leads connect to electrodes that are placed on the skin of your chest with a glue-like gel. The metal electrodes conduct your heart's activity through the wires and into the Holter monitor, where it's recorded. You wear a small pouch around your neck that holds the monitor itself.
Who can give you a holter monitor?
Your doctor may also order a Holter monitor if you have a heart condition that increases your risk of an abnormal heart rhythm. Your doctor may suggest you wear a Holter monitor for a day or two, even if you haven't had any symptoms of an abnormal heartbeat.
What to expect from a holter monitor?
Your doctor might also recommend a Holter monitor test to:
- Find out the causes of symptoms like chest pain, heart palpitations, shortness of breath, light-headedness, or fainting
- Diagnose an arrhythmia, or irregular heartbeat
- See how well your heart is working after a heart attack
- Check how well your pacemaker is working
- Determine if your medication is working properly
What is a holter monitor and what does it do?
Holter monitor. A Holter monitor is a small, wearable electrocardiogram (ECG) device that keeps track of the heart rhythm during everyday activities. It's typically worn for a day or two. A health care provider uses the information captured on the device to help diagnose a heart rhythm problem (arrhythmia).

Historically electrocardiography began in 1893 with the work of Einthoven's string galvanometer.[1] The Holter monitor is a device that works on Galvanometer's principle to record electrocardiographic signals from an individual who is going about his daily activities, like continuous ambulatory electrocardiography. From 1961 various other modalities and advance gadgets have been manufactured for this purpose. [2]

Can a Holter monitor be used for children?
In children, Holter monitor use is limited because of wires and cables. In 2011, the Federal Drug Administration approved a device which is wireless, water-resistant and allows for up to 14 days of continuous single-channel rhythm monitoring. The patients can trigger symptoms by pressing a button to start the recording and correlate symptoms with concurrent rhythm. A study which compared new wireless device with standard Holter monitor found that new wireless adhesive monitoring patch diagnosed more arrhythmic events than the Holter monitor. [10],[11]

How does Holter monitor work?
The Holter monitor runs on batteries and can be placed in a pocket or pouch worn around your neck or waist. Holter monitor has 5 to 7 wires called leads. The leads attach to metal disks called electrodes (small conducting patches), which are stuck onto your chest. The electrodes must be firmly attached to your chest so the Holter monitor gets an accurate recording of your heart’s activity. Tell your doctor if you are allergic to any tape or other adhesives. These electrodes are very sensitive, and they can pick up the electrical impulses of the heart. The impulses are recorded by the Holter monitor and give your doctor a 24-hour record of your heart’s electrical activity.
What is the test for irregular heartbeat?
If you have signs or symptoms of a heart problem, such as an irregular heartbeat (arrhythmia) or unexplained fainting, your doctor may order a test called an electrocardiogram (ECG) first. An electrocardiogram is a brief, noninvasive test that uses electrodes taped to your chest to check your heart’s rhythm. However, sometimes an electrocardiogram (ECG) doesn’t detect any irregularities in your heart rhythm because you’re hooked up to the machine for only a short time. If your signs and symptoms suggest that an occasionally irregular heart rhythm may be causing your condition, your doctor may recommend that you wear a Holter monitor for a day or so.

If the symptoms are less frequent, a longer-term monitor is the next step. Some Holter type monitors can be worn for up to 14 days. If long term monitoring is desired then there are non-wired monitors that can be carried around and placed on the skin when symptoms occur. That is not continuous though and only record when the monitor is placed on the chest. More recently there has been increasing use of monitors placed under the skin that can record continuously for up to 2 years. The Holter monitor is often the initial step, but there are many options available.
