Patient Education

If you were seeking information about a heart rhythm disorder 40 or 50 years ago, you would not have found out very much. It is only in recent decades that scientists have discovered how and why the heart sometimes beats irregularly. Once this basic process was understood, doctors could develop treatments for these debilitating, and sometimes deadly, disorders.

As a maker of imaging technology that allows doctors to “see” into a beating heart, Biosense Webster has played a major role in discovering how the heart’s electrical system works. Working together with doctors who specialize in treating electrical problems of the heart, we have also created the tools to treat — and even cure — many types of heart rhythm disorders.

If you or someone you love has been diagnosed with a heart rhythm disorder, you may be hearing lots of unfamiliar terms to describe the problem and what can be done to treat it. This part of our website is designed to explain, in plain language, the most common heart rhythm disorders (called “arrhythmias”). You’ll also find information on how these arrhythmias can be treated, and what to expect if your doctor orders one of the common tests to diagnose or treat a rhythm disorder. We hope this information will help you make sound decisions about your treatment.
