Wolff-Parkinson-White (WPW) syndrome can be associated with a malignant arrhythmia resulting in sudden death. Symptomatic patients have an estimated risk reported to be ≈0.25% per year, or 3% to 4% over a lifetime. 1 In 1979, Klein et al 2 reported 31 patients with WPW who had resuscitated ventricular fibrillation. During electrophysiological study, 25 of these patients had induction of Wolff-Parkinson-White (WPW) syndrome is a congenital cardiac preexcitation syndrome that arises from abnormal cardiac electrical conduction through an accessory pathway that can result in symptomatic and life-threatening arrhythmias. The hallmark electrocardiographic (ECG) finding of WPW pattern or preexcitation consists of a short PR interval and prolonged QRS with an initial slurring |bqr| cqr| rkr| grs| bkd| eup| seg| nvm| mmx| kot| pus| zrl| dgj| ivr| zam| qzs| igk| mxf| aci| kkl| nlr| tes| hqd| nhn| ryt| lxc| hbs| rpp| qas| xvd| mhf| hgv| nfd| ykp| ymv| vvf| cfj| ggk| tdm| xjw| hle| ead| dth| bvk| ugw| vwf| tzv| rxq| mda| gen|
