Studies on incidences of sports-related sudden cardiac death (SrSCD) are few and data are needed for the discussion of preparticipation screening for cardiac disease. ⋯ In Denmark, SrSCD is a rare occurrence and the incidence rate is lower than that of SCD in the general population. This may imply a low value of preparticipation screening of athletes in Denmark.

Comparative Study
Different characteristics of complex fractionated atrial electrograms in acute paroxysmal versus long-standing persistent atrial fibrillation.
Complex fractionated atrial electrograms (CFAEs) may represent a phenomenon associated with sources of atrial fibrillation (AF) and are being used increasingly as targets of catheter ablation. However, current methods have limited efficacy for characterizing CFAEs important to substrate arrhythmogenicity and do not measure electrogram morphology. ⋯ A novel method for quantifying CFAEs, independent of activation rate, has been developed. The method demonstrates greater significance in the difference between CFAE morphology in paroxysmal and long-standing AF compared with mean interval between CFAE deflections. The differences identified suggest that CFAE morphology may evolve as AF persists.
