Do you have an

irregular heartbeat?

It’s a more common question than you might think. Has something not been feeling right?
Have you experienced dizziness, unexplained fainting or shortness of breath?

If so, you may have an irregular heart rhythm (heartbeat) called arrhythmia. An Insertable
Cardiac Monitor (ICM) can help figure out what’s going on.

Use our list of questions to help guide a conversation with your doctor.

What is an irregular heartbeat?

A normal heartbeat (rhythm) is typically between 60 to 100 beats per minute. If your heart beats slower or faster, you may have an irregular rhythm (arrhythmia).

There are four common kinds of arrhythmia.

Is a SLOW heartbeat of fewer than 60 beats per minute

Is a FAST heartbeat of more than 100 beats per minute

A pause in your regular heartbeat, when your heart doesn’t beat for a few seconds

Atrial Fibrillation (AFib)
Is a heartbeat that beats chaotically and/or irregularly.


How is an

Arrhythmia diagnosed?

Because an irregular heartbeat can come and go, diagnosis can be tricky. While other methods of heart monitoring only record your heartbeat for up to a month, an ICM can monitor continuously for years. Some ICMs connect wirelessly to your cell phone via bluetooth to send data to your doctor or clinic automatically.1




An ICM—also sometimes referred to as loop
recorder—goes under the skin near your heart and can monitor for years.


Small conducting patches (electrodes) stick to your chest and attach to a small monitor that records heartbeats for up to two days.


A recorder attaches to your skin for 30 days, allowing you to press a button when you feel symptoms.


Fitness wearables and smartwatches may be able to display a short history of your heart rhythm.

Using a wearable may help determine if you should speak to your doctor about more detailed and consistent monitoring with a device such as an ICM, which may help with diagnosis.


Many people who have AFib may not experience the symptoms. It is important for your doctor to accurately diagnose your condition and understand how often and how long it occurs.
