Background: In this study we compared P wave duration and dispersion (PWD) in patients with essential hyperhidrosis and healthy control subjects.

Methods: Twenty subjects (mean age 28 ± 7 years) with essential hyperhidrosis and twenty healthy control subjects (mean age 31 ± 8 years) were included to study. Twelve leads surface ECG recorded at a peper speed of 50mm/s was obtained from all participants. The change in maximum and minimum P wave duration was measured manually and difference between two values was defined as PWD. Transthoracic echocardiographic examination was performed in all participants.

Results: There was no difference between two groups in terms of baseline demographic properties. On echocardiographic examination no significant cardiovascular disorder was detected. Maximum and minimum P wave duration were found to be similar in hyperhidrotic subjects and healthy controls (111 ± 10 vs.110 ± 6 p = 0.6, 64 ± 12 vs. 67 ± 9 p = 0.4, respectively). PWD in hyperhidrotic subjects was also found to be identical in controls (47 ± 8 vs. 43 ± 9 p = 0.1).

Conclusion: These results suggested that hyperhidrotic subjects had no prolonged P wave duration and increased PWD compared to healthy subjects and these patients were not prone to the atrial conduction abnormalities.
