Spatial Magnitude Electrocardiogram in Normal Men

The normal composite electrocardiogram.

The normal electrocardiogram.

O NE of the most difficult tasks which confronts the w orker in the life sciences is to define a normal. The difficulty is compounded when the measurement to be made is affected by many variables which differ in importance from time to time. These remarks apply to the electrocardiographer, and to the normal electrocardiogram. Some variables which affect the electrocardiogram are quite well know...

The Corrected Orthogonal Electrocardiogram and Vectorcardiogram in 510 Normal Men (frank Lead System).

A NUMBER of reports on normal ranges of corrected orthogonal electrocardiographic measurements have appeared in the literature.'-12 They were derived, however, from limited numbers of subjects and the types of electrocardiographic and vectorcardiographic measurements varied largely from one study to another. The reported results are therefore not always strictly comparable. In spite of these li...
