Electrocardiographic abnormalities (spontaneous in 6 and provoked in 14) were recognized in 5 symptomatic and 15 asymptomatic patients. Mean PR (188 \u00b1 18 vs. 184 \u00b1 24 ms) and QT (362 \u00b1 34 vs. 382 \u00b1 28 ms) intervals and ST-segment elevation (2.28 \u00b1 0.42 vs. 2.70 \u00b1 0.77 mm) were similar in both groups. The PR interval was slightly longer in males than females (191 \u00b1 21 vs.168 \u00b1 18 ms, p = 0.042), but ST-segment elevation (2.70 \u00b1 0.78 vs. 2.24 \u00b1 0.26 mm) was similar. The HV interval was longer in males than females (57 \u00b1 4 vs. 50 \u00b1 4 ms, p = 0.047). Ventricular arrhythmias were induced in 40% of asymptomatic patients. There was no significant difference in age, sex, PR interval, ST-segment elevation, or HV interval between inducible and non-inducible patients. A defibrillator was implanted in 8 patients. During 16 \u00b1 2 months of follow-up, one symptomatic patient had appropriate device therapy. None of the asymptomatic and non-inducible patients experienced a cardiac event. Electrophysiologic data have no role in predicting inducibility in programmed stimulation.<\/jats:p>","DOI":"10.1177\/021849230501300311","type":"journal-article","created":{"date-parts":[[2013,5,6]],"date-time":"2013-05-06T09:37:22Z","timestamp":1367833042000},"page":"241-246","source":"Crossref","is-referenced-by-count":3,"title":["Clinical
