The latter system has no compensating resistor networks simplifying electrical maintenance and employs large sponge electrodes which circumvent problems with lead placement.

However, very little applied research has been done using Helm's lead system. In contrast, vectorcardiographic criteria for left anterior fascicular block are applicable whether or not there is an accompanying inferior infarction.8"10'13"15 The concept of evolving electrocardiographic criteria for left anterior fascicular block based on vectorcardiographic features is not without précèdent.9'11'19 In response to a Cited by: Frank’s system, however, was finally adopted as standard system for vectorcardiography by late due to several advantages: simplicity of application, reasonably accurate representation of heart dipole and adequate number of electrodes to better approximate the fixed dipole assumption of the heart.Cited by: 9.

Millard performed an interesting series of experiments to show the Brody effect on the ECG signal (Voukydis, ). He recorded the x, y, and z signals from a dog using the Nelson lead system and calculated the magnitude and the two angles of the electric heart vector in spherical coordinates.

The result is shown in Figure   Pediatric ECGs vary by age; tracings change considerably from birth through adulthood. In the ECG tracing above, the T waves are inverted. Nevertheless, as we outline here, the tracing is normal in a 9-year-old child; the T waves may not revert to normal until he reaches : Loren A.

Introduction. The LSF is supplied exclusively by the septal perforating branches of the LAD. 9 Critical lesions of the LAD before the first septal perforating branch are the main cause of LSFB in developed countries, and it is a major determinant of predominant anterior forces (PAF) from V 1 to V 3 during acute myocardial ischemia.

The latter system has no compensating resistor networks. ECG axis results had been obtained. Careful interpretation and manual calculation of the ECG tracings could not compete with prompt and accurate vectorcardiographic (VCG) tracings of the cardiac axis in the Frontal plane.
