[Frequency versus time domain analysis in signal-averaged ECG: reproducibility and differences in predicting high risk patients with myocardial infarction].

Frequency domain analysis (FDA) and time domain analysis (TDA) are techniques for the diagnostic interpretation of signal averaged ECG. To overcome the limitations of TDA, such as noise and conduction disturbances, FDA has been developed. But the reproducibility of FDA, especially spectral temporal mapping analysis, results are significantly lower than that of TDA. We examine the difference of two methods, and the role in high risk patients with myocardial infarction. Low amplitude signal (LAS) and area ratio (AR) are independent predictors of inducible sustained monomorphic ventricular tachycardia (SMVT) by programmed ventricular stimulation. The combined use of TDA and FDA enhanced the accuracy in predicting inducible SMVT.

Catheter ablation of atrioventricular accessory pathway with decremental properties connecting to the tricuspid annulus.

A 65-year-old male with Wolff-Parkinson-White syndrome presented with atrial fibrillation. The patient was found at the electrophysiological study to have two accessory pathways, a Kent fiber and an atrioventricular accessory pathway with decremental properties. The latter pathway conducted exclusively in the antegrade conduction and the ventricular insertion site was the tricuspid annulus. Both accessory pathways were successfully abolished by radiofrequency catheter ablations at the tricuspid annulus. We propose that an atrioventricular accessory pathway with decremental conduction may have various forms concerning not only sites of origin, but also sites of insertion.
