In this study, P wave duration and dispersion (PWD) were measured in 30 heavy smoker, 30 light smoker and 30 nonsmoker subjects. There were no significant difference among heavy smokers, light smokers and nonsmokers with respect to maximum P wave duration and PWD (117±9ms, 116±8ms, 115±6ms ANOVA p=0.78, and 48±10ms, 45±11ms, 43±8ms, one-way ANOVA p=0.14, respectively). Minimum P wave duration was also similar in three groups. (69±10 ms, 70±13ms, 72±9ms, one-way ANOVA p=0.51). We also found no dose dependent-relation betweenthe duration of smoking, the number of cigarettes smoked, and P wave duration. Habitual cigarette smoking alone does not alter P wave duration and PWD in otherwise healthy young subjects.
