The spatial velocity electrocardiogram (SVECG) was recorded in 61 subjects of normal men by the spatial velocity electrocardiograph manufactured by Mori et al. using Frank system simultaneously recorded with its scalar ECG's. Atrial component of the SVECG was analyzed quantitatively as well as qualitatively. The normal atrial SVECG is composed of three patterns: two-peaked, three-peaked and four-peaked patterns. The third and/or fourth peaks are the tallest in normal subjects. It can be considered that the first peak reflects the excitation of the right atrium, the second peak do those of the interatrial septum and both atria, and the third and fourth peaks reflect principally the depolarization of the left atrium and a part of the atrial repolarization. Two-peaked pattern is also recorded in few cases of normal subjects. In the two-peaked group the first peak contains the right or both atrial components and the second peak reflects mainly the left atrial excitation, and then both peaks cannot be thought simply to reflect the activation of right and left atria. The two-peaked pattern manifests the uniformity in inscription velocity of the efferent and afferent limbs of the spatial P loop because of its smooth and elliptic or linear configuration.
