Abstract

Nikolaos G Eleftherakis and Nikolaos D Andreou

A male child, three years old, with primitive neuroectodermal tumor (PNET) was admitted to our department because of episodes of apnea with syncope. Twenty four hr ambulatory electrocardiographic monitoring revealed extremely long sinus pauses, the longest being thirty four seconds, followed by sinus tachycardia. Permanent pacing reduced the frequency, duration and severity of episodes.
