Spatial Velocity in the Second Part of QRS in the ECG of Rabbits

  • Radoslav Lolov

Abstract

The spatial velocity of the second part of QRS is a relatively new parameter which enriches the diagnostic capacity of the electrocardiogram (Chorão de Aguiar et al., 1979). This parameter was defined at first by Hellerstein and Hamlin (1960) after experiments performed on dogs, and it was studied later on for healthy subjects (Draper et al., 1964; Chorão de Aguiar et al., 1979), as well as for patients with different cardiopathies (Gamboa et al., 1967; Chorão de Aguiar et al., 1976).
