Abstract
<pre> <strong>Introduction: </strong>Patients with a lifelong history of non-documented palpitations often have paroxysms of reentrant supraventricular tachycardia, potentially curable by an ablation procedure. Clinical documentation of such arrythmia is often difficult and can only be diagnosed by an electrophysiological study (EPS). Many times the EPS is negative for such arrythmias but, in some patients, there is induction of atrial fibrillation (AF). We studied whether the induction of AF in such patients, with no previous history of documented AF, is associated with the development of clinical AF in the future. </pre> <pre> <strong>Methods</strong>: Single center retrospective study of consecutive patients with symptoms of sudden onset tachycardia that underwent a negative diagnostic EPS looking for reentrant supraventricular tachycardia, from January 2000 to February 2018. Patients were divided into two groups based on the induction of AF at EPS. Follow up was made using medical records from the outpatient clinic, emergency room visits and hospital discharge notes. </pre> <pre> <strong>Results: </strong>We studied a total of 44 patients (mean age of 55,9 ± 19,1 years, 33 women) with a negative diagnostic EPS. Atrial fibrillation was induced in 23 (52,5%) patients (iAF group). During a mean follow-up of 73±50 months, 13 patients developed clinical AF: 10 in the iAF group (43,5%) and 3 in the non-iAF group (14,3%). Induction of AF at EPS was significantly associated the latter development of clinical AF (OR 4,6 CI 95%: 1,05 – 20,16), as shown by Kaplan-Meier survival curves (Figure 1). In multivariate analysis considering age, gender, mean follow-up time and type of palpitations (irregular vs regular), only irregular palpitations was associated with latter development of clinical AF (OR 8,64 CI 95%: 1,50 – 49,89)(Table 1).</pre> <pre> <strong>Conclusion: </strong>Induction of AF in patients complaining of non-documented paroxysmal tachycardia is significantly associated with development of clinical AF in the future. Therapeutic interventions at this stage could potentially change the prognosis of these patients by preventing future thromboembolic events and progression to clinical AF. Future trials are warranted. </pre> <p> </p>
