Key result
Four-electrode measurement shows the QRS complex arises from a fixed-location heart dipole with 5% accuracy.
Why the study?
Precise research measurements of mirror patterns and the theoretical significance of QRS complex results on normal human subjects were needed to evaluate the fixed-location equivalent heart dipole concept.

Supports fixed dipole model for normal QRS; leaves open validation in disease and any ECG practice change.
Demonstrates that the QRS complex on the body surface of normal subjects arises from a fixed-location equivalent heart dipole, challenging the 'proximity' potential concept.
Ernest Frank (1955) studied Normal human subjects. Four-electrode single-channel system for measuring cancellation potentials was evaluated on Accuracy of fixed-location equivalent heart dipole for QRS complex. Measurement of cancellation potentials using a four-electrode system demonstrated that the QRS complex arises from a fixed-location equivalent heart dipole to an average accuracy of 5%.
