The scoop on the new syncope guidelines

Win-Kuang Shen, M.D., electrophysiologist and Cardiology chair at Mayo Clinic's campus in Phoenix/Scottsdale, Arizona, discusses the recently released 2017 American College of Cardiology/American Heart Association/Heart Rhythm Society (ACC/AHA/HRS) Guideline for the Evaluation and Management of Patients With Syncope.

Approximately 40 percent of the U.S. population has syncope, which can be associated with many conditions. The goal of the ACC/AHA/HRS syncope guidelines is to provide a comprehensive recommendation for this very diverse patient population, including:

  • Setting a standard definition for syncope

  • Setting a standard practice

  • Identifying the areas where additional data is needed

What testing should be performed?

The Syncope Guideline committee determined that a detailed history and exam, as well as an electrocardiogram, is necessary. However, there are several class III recommendations, including imaging and broad blood testing, that should be included in select patient populations.

The committee also developed a list of serious medical conditions to determine the need for hospital admission.

Driving after syncope

The committee determined that physicians should be familiar with local and federal laws regarding driving after syncope. The Department of Transportation has strict rules regarding commercial driving, so the committee deferred to the federal laws concerning driving after syncope. The committee also created a summary table with suggestions related to private driving.
