Sinus node function, including automaticity, conduction, and refractoriness, can be studied in the human electrophysiology laboratory. This review details the current methods used for such studies and discusses their clinical value. Of special emphasis in this article is the role of sinus node electrography in the clinical laboratory. Included also is an update of the data relating the duration of sinus node depolarization as measure on sinus node electrograms to other parameters that assess sinus node function as well as data supporting the direct relationship between the duration of the sinus node depolarization as the severity of sinus node dysfunction.
窦房结功能，包括自律性、传导性和不应期，可在人体电生理实验室进行研究。本综述详细介绍了目前用于此类研究的方法，并讨论了它们的临床价值。本文特别强调了窦房结电图在临床实验室中的作用。还包括了有关窦房结电图测量的窦房结去极化持续时间与评估窦房结功能的其他参数之间关系的数据更新，以及支持窦房结去极化持续时间与窦房结功能障碍严重程度之间直接关系的数据。
