The predictive value of different combinations of these independent electrocardiographic (ECG) signs in distinguishing atrioventricular reentrant tachycardias (AVRTs) through a concealed accessory pathway (AP) versus atrioventricular nodal reentrant tachycardias (AVNRTs) are discussed in detail. In addition, the adjunctive diagnostic value of simple, bedside clinical variables and their combinations to the ECG interpretation in differentiating both tachycardia mechanisms is also reviewed.

Sin embargo, su utilización no está exenta de problemas. Así, hasta un 30% de los pacientes experimenta descargas inapropiadas y un 20% puede recibir múltiples descargas, lo que causa deterioro de la calidad de vida, hospitalizaciones, proarritmia e incremento de la mortalidad 1-3 .

We hypothesized that ablation of all E-IDC and CC during sinus rhythm is a safe and effective ablation strategy. The purpose of this study was to determine the long-term efficacy and to identify the success predictor of substrate based ablation of sustained monomorphic ventricular tachycardias (SMVT) in patients with myocardial infarction.

Introduction: Usefulness of the interval between the last pacing stimulus and the last entrained atrial electrogram (SA) minus the tachycardia ventriculoatrial (VA) interval in the differential diagnosis of supraventricular tachycardias with long (>100 ms) VA intervals has not been prospectively studied in a large series of patients. Our objective was to assess the usefulness of the difference SA-VA in diagnosing the mechanism of those tachycardias in patients without preexcitation. The results were compared with those obtained using the corrected return cycle (postpacing interval-tachycardia cycle length-atrioventricular [AV] nodal delay).
