GIALAFOS, E.J., et al .: P Wave Analysis Indices in Young Healthy Men. Data from the Digital Electrocardiographic Study in Hellenic Air Force Servicemen (DEHAS).P wave analysis from the 12‐lead ECG is a recent contribution of noninvasive electrocardiology. P wave analysis indices (maximum and minimum P wave duration, P wave dispersion [P dis = P max − P min ], adjusted P wave dispersion [AP dis = P dis /√measured leads], summated P wave duration [P sum ], standard deviation of P wave duration [P sd ], mean P wave duration [Pmean]) can predict atrial arrhythmias. However, the definitions of all these indices are based on few studies. The aim of this analysis was to define normal values of these indices and the examine possible associations between P wave indices and clinical variables. The study included 1,353 healthy men,24 ± 3years of age, who answered a questionnaire and underwent a detailed physical examination and a digitized 12‐lead surface ECG. All P wave indices were analyzed by two independent investigators. Mean values of the ECG indices were:P max : 96 ± 11 ms, P min : 57 ± 9 ms, P dis : 38 ± 10 ms, P sum : 924 ± 96 ms, P sd : 12 ± 3,AP dis : 11 ± 3 ms, and P mean : 77 ± 8 ms. Age was significantly related withP max (r = 0.277, P < 0.01), P min (r = 0.255, P < 0.001), P sum (r = 0.074, P < 0.01), and P mean (r = 0.074, P < 0.01). All ECG indices were significantly associated with the R‐R interval, and among each other. This study defined normal indices of wave duration and correlations among them. These markers may play an important predictive role in patients with atrial conduction abnormalities. (PACE 2003; 26[Pt. II]:367–372)
