Overview of the clinical electrophysiology study.
Clinical electrophysiology testing is now a standard, useful technique for assessing patients with bradyarrhythmias or tachyarrhythmias. The technique requires specialized training and equipment. The recording equipment and program stimulator have evolved to sophisticated devices allowing accurate reproduction of intracardiac electrograms and timing of programmed extrastimuli. Electrophysiologic studies are useful for determining the mechanisms of a tachycardia or bradycardia and identifying the most appropriate therapy, whether it be pacing, antiarrhythmic medications, transvenous ablation, or electrosurgery.
