Abstract

Syncope is a common medical problem which can result from many etiologies, including cardiac dysrhythmias. Because ambulatory monitoring usually fails to capture a syncopal episode, electrophysiologic testing has been used to elucidate dysrhythmic mechanisms in patients with recurrent syncope. To assess whether findings on ambulatory monitoring not obtained during syncope can be used to indicate the results which are found on electrophysiologic testing in patients with recurrent syncope, we reviewed the ambulatory monitoring records of 59 such patients referred for electrophysiologic testing. Although 29 patients had abnormalities on electrophysiologic testing, 13 of which were severe, in only six were the findings suggested by the abnormalities recorded during ambulatory monitoring. Twenty-one patients actually had concordance between electrophysiologic testing and ambulatory monitoring results, but in 15 of the 21 results of both tests were normal. Severe abnormalities were more frequently detected in our patient population by electrophysiologic testing than by ambulatory monitoring, especially if patients had organic heart disease.
