Spatial Vector Electrocardiography
more commonly encountered deformities are discussed. In addition, the isolated T-negativity syndrome is described, a rare type of precordial T-wave inversion which may be encountered in normal subjects and is often indistinguishable from the ST-T deformity of recent myocardial infarction. The spatial vector method of interpretation is found to provide a simple yet rational basis for the interpr...
متن کاملAtlas of Spatial Vector Electrocardiography
BIOLOGICAL CHEMISTRY. By Alexander Gero. New York, The Blakiston Company, 1952. xvi + 340 pp. $5.00. This book is proposed to serve as a nexus between undergraduate organic chemistry and graduate or medical school biochemistry. An indication of its scope can be gained by a listing of the table of contents. There are two chapters on physical chemistry, single chapters on the electronic theory of...

متن کاملSpatial vector electrocardiography; a method for calculating the spatial electrical vectors of the heart from conventional leads.
A new method for the interpretation of conventional electrocardiographic leads is presented. It is based upon evidence that all body surface leads tend to record from the same resultant electrical forces. The various leads write different QRS and T contours in a given case, then, simply because the axis for each of the leads has a different direction in the electrical field and therefore regist...
متن کاملLead Field Scalar and Loop Spatial Electrocardiography
Spatial electrocardiography based on the lead field concept of McFee and Johnston appears to be theoretically more satisfactory than other systems of vectorcardiography. To determine the normal range of planar loop patterns to be expected with this technic and to compare them with those derived by previous methods, a survey of young adult males has been carried out with particular reference to ...
