Risk stratification of sudden cardiac death in subjects with asymptomatic ventricular preexcitation: diagnostic value of non-invasive and invasive methods

Abstract Introduction In subjects with asymptomatic ventricular preexcitation (AVP) guidelines recommend follow-up by non-invasive methods. However, in some patients accessory pathways (APs) show high-risk invasive parameters and risk of sudden death. Objectives To assess the association between stratification (NIRS IRS) AVP our center. Material methods Retrospective observational study 58 AVP, underwent NIRS IRS. Association (electrocardiogram, holter ergometry testing) IRS variables (AERP ≤250 msec, SPERRI atrioventricular reentrant tachycardia or AF, multiple APs) from electrophysiological (EPS), sensitivity specificity to predict a EPS were determined. Results Of (n=41), 55% had previously low-risk (n=11) while 78% (n=30) (p=0.05). A (S) 27% (E) 47% EPS. Conclusions population, 1 every 2 presented The present low S E for patients.
