INTRODUCTION AND OBJECTIVES: Over the last few years, our understanding of the mechanisms underlying cardiac arrhythmias has increased substantially. However, few data on their prevalence exist. Our objectives were to analyze the prevalence of cardiac arrhythmias and conduction disturbances in cardiology clinic outpatients and to determine the number of patients with a class-I or -IIa recommendation for electrophysiological studies (EPS).
PATIENTS AND METHOD: We investigated cardiac arrhythmias and conduction disturbances in 2045 patients and determined their prevalence in those seen for the first time. Specific conditions investigated included supraventricular and ventricular arrhythmias, ischemic disease with an ejection fraction (EF) <30%, second-degree or higher atrioventricular (AV) block, intraventricular block, and sick sinus syndrome.
RESULTS: In total, 798 (39%) of all patients and 153 of the 704 (22%) seen for the first time presented with 1 or more of the specified conditions. Their distribution in all patients was: atrial fibrillation, 524 (26%); atrial flutter, 34 (2%); narrow-QRS tachycardia, 58 (3%); ventricular arrhythmias or EF<30% due to ischemic disease or both, 46 (2%); AV block or sinus dysfunction, 68 (3%); intraventricular block, 157 (8%); and other conditions, 4 (0.2%). Some 7% (143/2045) of all patients and 3.5% (25/704) of those seen for the first time had an indication for EPS.
CONCLUSIONS: a) Almost 40% of all patients seen in a cardiology outpatient clinic and 1 in 4 of those seen for the first time presented with a cardiac arrhythmia or conduction disturbance; and b) more than 3% of patients seen for the first time had an indication for EPS.
