Occasionally, patients present with recurrent syncope or palpitations. In this setting, an arrhythmic cause of syncope may be sought. Options include Holter monitoring, which has a low yield, and event recording. The goal is to document the patient’s rhythm during symptoms. Individuals with infrequent symptoms are best served by the implantation of a loop recorder, which may have a battery life of 2-4 years.

If such techniques are not practical, a provocative electrophysiologic study can be performed.
