Abstract
QTc intervals in leads D-2 and V-2 were significantly increased in habitual smokers compared with nonsmokers (408 +/- 36 vs 378 +/- 21 ms [p < 0.01] a nd 412 +/- 38 vs 382 +/- 22 ms [p < 0.01], respectively). The mean of the m aximum corrected QT interval in any lead was significantly longer in smoker s than in nonsmokers (422 +/- 42 vs 391 +/- 26 ms, p < 0.01), and habitual smokers had significantly increased QTc dispersion compared with nonsmokers (49 +/- 16 vs 36 +/- 11 ms, p < 0.05).
