Cardiac electrophysiology has evolved from primarily managing arrhythmias with drugs to using various nonpharmacologic methods to detect and terminate them. Among these are treatment options for patients with ventricular tachycardia and fibrillation, the chief cause of sudden cardiac death. Pharmacotherapy has proved inadequate for many patients. Implantable cardioverter-defibrillators (ICDs) can effectively terminate malignant ventricular arrhythmias and improve survival in high-risk populations.

Methods for managing patients with atrial fibrillation (AF) continue to evolve. Guidelines for anticoagulant therapy have been updated and expanded. Nonpharmacologic therapies can prevent embolic strokes in patients who are at increased risk of bleeding. Catheter ablation for AF is now mainstream and low risk, and force-sensing catheters have improved outcomes and reduced complications. Surgical management is recommended for paroxysmal or persistent AF during concomitant heart surgery. Surgical ablation can be considered in patients whose AF is refractory to antiarrhythmic drugs. Nevertheless, reliable evidence-based recommendations for surgical management of AF are still needed.

Managing arrhythmias in special populations, including pregnant women and athletes, poses special problems. In pregnant women, it is complicated by the need to avoid harming the mother and the fetus. During pregnancy, only severe symptoms or hemodynamic compromise should be treated.

The Ali Massumi Cardiac Arrhythmia Symposium is designed to provide electrophysiologists, cardiologists, internists, and associated professionals with state-of-the-art information on the fundamental mechanisms of cardiac arrhythmias and with best practices in clinical diagnosis, evaluation, and management of abnormal heart rhythms.

After this activity, the participant should be able to:

  • Cite guidelines for the management of AF, including stroke risk factors.

  • Discuss treatments for reducing the risk of stroke in patients with nonvalvular AF.

  • Discuss the management of arrhythmia in special populations, including pregnant women and athletes.

  • Understand how to improve the diagnosis and management of ventricular tachycardia and thus lessen the risk of sudden death and improve quality of life.

  • List the complications of ICD therapy and ways to prevent and manage them.

Cardiologists, cardiologists with an interest in electrophysiology, cardiac electrophysiologists, internists with an interest in cardiology, cardiology fellows, cardiac catheterization laboratory technicians, and family and general practitioners.
