Abstract

A 23 year-old man presents with palpitations and presyncope with evidence of non-conducted P waves at low heart rates, and frequent narrow-complex tachycardia. A dual chamber pacemaker was implanted for presumed sinus node dysfunction, second-degree atrioventricular (AV) block and atrial flutter. Many years and two pacemaker generator changes later he underwent an electrophysiology study that revealed normal AV node and His-Purkinje function, a concealed accessory pathway, and orthodromic atrioventricular reentrant tachycardia. We scrutinize his case, discuss AV conduction anomalies, and consider an alternative investigation strategy

About the Clinical Cases Database

T​he Foundation Years Clinical Cases Database is​ a selection of 600 peer-reviewed clinical cases in the field of patient safety and clinical practice, specifically focused on the clinical information needs of junior doctors, based around the Foundation Year Curriculum programme (MMC). The cases have been chosen to align with the Foundation Year Curriculum.

The database is fully searchable, or can be browsed by medical specialty. Abstracts can be read free of charge, however a subscription is required in order to read the complete cases.
