Abstract: A cardiogoniometry or vector cardiography system wherein signals directly derived from the bioelectrical field are not directly processed as orthogonal data but are instead especially orthogonalized in an analog computing network. Orthogonalization is based on a derivation electrode configuration space with sloping sagittal and frontal planes. The orthogonalized signals are processed in a cardiogoniometer and are also jointly recorded on a commercial electrocardiograph in parallel thereto. All the represented data which can be used for diagnosis purposes are referenced to a biological zero line, which differs from the electrical neutral point. The cardiogoniometer permits a vectorial real time measurement on the patient.
