We evaluated the diagnostic yield of event loop recorders in ambulatory patien ts referred for palpitations, dizziness or syncopal events and in whom a previou s Holter recording was not diagnostic. A total of 96 patients were studied, 50 ( 52%) were men and 46(48%) were women with a mean age of 37±10 years. Mean dur ation of the recording was 5.2±2.3 days. During the recording period, 24 of the 96 patients(25%) remained asymptomatic. Automatic recordings revealed signific ant arrhythmias in four (16.7%) patients, which included two(8.3%) cases of at rial fibrillation, one(4.2%) non-sustained ventricular tachycardia(VT) and one (4.2%) second degree atrio-ventricular(AV) block. The manual function of the r ecorder was used by 72(75%) patients while they were symptomatic. Palpitations were the most common symptom, which corresponded most frequently to normal sinus rhythm(43.1%), followed by sinus tachycardia (16.7%). An arrhythmic substrat e was found in 29 (40.3%) patients, including 13(18.1%) with isolated ectopic beats of supraventricular and/or ventricular origin, 14 (19.4%)-with supravent ricular tachycardia (SVT) and 2 (2.8%) with second degree AV block. The data of our study showed that the ambulatory use of an event loop recorder in young pat ients during a mean period of 5 days was highly useful to elucidate the potentia l cause of their symptoms. The particular use of the manually triggered function during symptoms allowed to establish a clear correlation between symptoms and a rrhythmic events including sinus tachycardia in 75%of patients.
