What is arrhythmia?
What is an ECG?
What is ambulatory cardiac monitoring?

Do you sometimes experience a skipped beat in your chest? Or feel a racing of the heart?

Your heart might beat too slow, too fast, or with an irregular beat. It may feel like skipped beats or a brief pause. It might be so slight that you don’t even feel it or experience any symptoms. You may have an irregular heartbeat or an arrhythmia. Fortunately, there are treatments available for arrhythmias. However before you can begin treatment, the condition must be diagnosed.

A simple, one-time test with the Zio by iRhythm system could be all you need to find out whether or not you have an arrhythmia and what kind you have. Your doctor can then use this data to prescribe the most effective form of treatment.

What causes arrhythmias, or irregular heart rhythms?

Arrhythmias may be caused by many different factors, including prior heart attack or heart disease, high blood pressure, diabetes or sleep apnea. Irregular heart rhythms can also occur in "normal, healthy" hearts.

What is atrial fibrillation (AFib)?

Atrial fibrillation (also called AFib or AF) is a quivering or irregular heartbeat (arrhythmia) that can lead to blood clots, stroke, heart failure and other heart-related complications. At least 2.7 million Americans are living with AFib.

Normally, your heart contracts and relaxes to a regular beat. In atrial fibrillation, the upper chambers of the heart (the atria) beat irregularly (quiver) instead of beating effectively to move blood into the ventricles.

For more information, visit Arrhythmia Alliance and the American Heart Association website.

You can use the the interactive AFib Risk Assessment tool to help estimate your risk of AFib.

An electrocardiogram — abbreviated as EKG or ECG — is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on ECG will show the timing of the top and lower chambers. For more information please visit the American Heart Association.

An ambulatory ECG records the electrical activity of your heart while you are doing your normal everyday activities.

“Ambulatory” means that you are able to stand and walk, and are not stationary or motionless. Many heart problems are only detectable during activity such as standing or walking and will not appear in a brief test in your doctor’s office.

Zio vs. Holter monitoring

The Zio monitor can be comfortably worn for up to 14 days. Holter monitors can be worn for 24 to 48 hours, limiting the time to record any irregular heart rhythms you may have. Zio is able to capture data for the 51% of patients who have their first symptom-triggered arrhythmia after 48 hours.1

myZIOTM makes it easy to record your symptoms as they occur.

Now you don’t have to carry a separate Patient Instructions and Button Press Log book to record your symptoms as they occur.

A simple path to a clear diagnosis

Record

After the comfortable, easy-to-wear Zio monitor is applied, the Zio patch records and stores every single heartbeat.

Analyze

These recordings are analyzed by a powerful Zio system that identifies any irregular rhythms you’ve experienced—how many, what type, and when. In a study, physicians were ablet o reach a diagnosis 90% of the time with the Zio system2.

A definitive diagnosis to accelerate your care

Your doctor receives a clear report that shows how many and what types of irregular heart rhythms you experienced, as well as your normal heart rhythm, and when they happened -- all to help determine the best course of treatment.
