Electrocardiographic correlates of ventricular activation sequence were studied in 22 Macaca mulatta monkeys, aged 1-18 years, and 145 human subjects, aged 11-72 years, using the corrected orthogonal lead system of McFee-Parungao and the dipolar elec

The orthogonal electrocardiography was a further development of Einthovens conception of electrocardiography. It eliminates the redundancy of the 12-lead ECG and offers a more precise and illustrative image of the model of an equivalent dipole. It wa

In early postnatal life, human cardiac electric field undergoes dramatic changes resulting from the adaptation of the heart to new hemodynamic conditions. For the study of the effect of changes in ventricular geometry as well as in spatial orientatio

There is scarcity of quantitative studies on the relationship between somatometric characteristics of chest configuration and vectorcardiographic variables. The objective of this study was to give a quantitative description of these relations in orde

The cardiac electrical field is important not only because of its diagnostic significance, but also as a biological and biophysical phenomenon. As such, it has become a research target of biologists, biophysicists and biomathematicians. It has also b

Axial McFee-Parungao lead system vectorcardiograms were obtained in 55 patients with type atrial septal defect, aged 3-24 years, prior to and in average 3 years after surgical repair of the defect. Changes of the QRS loop observed after intervention

A realistic computer model of propagation of ventricular activation was used to study the effects of varying the position of specific conduction system terminations in the left ventricle and the septum, representing the sites of initial activation, o

Reference values of dipolar electrocardiotopogram of ventricular depolarization are presented. The data for establishing reference values in the McFee-Parungao lead system were obtained by manual processing of 145 records of healthy subjects (64 wome
