摘要：

A new procedure for searching the P wave in the corrected orthogonal electrocardiogram (VCG) was developed on the basis of VCG representation in spherical coordinates. The time course of the angle azimuth shows a well defined configuration Pφ{symbol} which is suitable for searching the P wave. At least normal VCGs regularly show the Pφ{symbol} configuration even if P waves are not visible in any of the related amplitude curves. The validity of Pφ{symbol} for the P wave recognition is discussed by electrophysiological considerations, and it was tested by comparison of the time course of Pφ{symbol} with that of well visible P waves in the magnitude curve of the very same VCG. Superposition with disturbance vectors yielded that Pφ{symbol} is more stable against distortions than the P wave in the magnitude curve. A digital algorithm was examined by comparison with data obtained by visual evaluation and with the output data of a common computer program for the very same VCGs. Additionally, the P wave duration and the azimuth of the atrial repolarization vector were compared with related data taken from literature. The results show that P wave recognition by using the Pφ{symbol} configuration is a valid and reliable method. © 1979.
