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.

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.
