title: Electrophysiologic evaluation of sinus node function.
abstract: Sinus node dysfunction can be evaluated by invasive and noninvasive means. In this article, invasive testing of sinus node function and its clinical utility are reviewed. Sinus recovery times, sinoatrial conduction times, sinus node refractory periods, and sinus node electrograms are all reviewed in detail, with regard to both theory and practice.
