Timing of Ablation and Prognosis of Patients With Electrical Storm and Scar-Related Left Ventricular Dysfunction.

Although radiofrequency catheter ablation (RFCA) is indicated in electrical storm (ES) refractory to antiarrhythmic drugs, its most appropriate timing has not been determined. Our objective is to analyse the impact of the timing of RFCA on 30-day mortality in patients with ES and previous scar-related systolic dysfunction. In this multi-centre study, we analysed 104 patients (age: 72 ± 10, left ventricular ejection fraction: 30 ± 6%) attended consecutively due to an ES caused by monomorphic ventricular tachycardia.

Variability in interpretation of the electrocardiogram in young athletes: an unrecognized obstacle for electrocardiogram-based screening protocols.

Aims: To assess in young athletes (i) the variability in the percentage of abnormal electrocardiograms (ECGs) using different criteria and (ii) the variability in ECG interpretation among cardiologists and sport physicians.

Methods And Results: Electrocardiograms of 138 athletes were categorized by seven cardiologists according to the original European Society of Cardiology (ESC) criteria by Corrado (C), subsequently modified by Uberoi (U), Marek (M), and the Seattle criteria (S); seven sports physicians only used S criteria. The percentage of abnormal ECGs for each physician was calculated and the percentage of complete agreement was assessed.

[Quality of life differences in patients with typical atrial flutter following cavotricuspid isthmus ablation].

Introduction And Objectives: The aim of the study was to assess and measure health-related quality of life (HRQoL) changes in patients with typical atrial flutter following catheter ablation. The outcome was standardized and normalized to the Spanish population adjusted by age and sex.

Methods: Ninety-five consecutive patients who had undergone cavotricuspid isthmus ablation were included.
