title: Electrophysiologic studies in cardiac arrhythmia. When and why they are useful.
abstract: Electrophysiologic studies have contributed significantly to the improved understanding of cardiac arrhythmias. Whereas previously treatment of these arrhythmias was largely empirical, electrophysiologic studies have paved the way for a scientific approach to evaluation and management of the patient with a potentially life-threatening problem.
