Vectorcardiography was developed by E. Frank in the mid 1950s.Since the human body is a three-dimensional structure, the basic idea is to construct three orthogonal leads containing all the electric information. The three leads are represented by right-left axis (X), head-to-feet axis (Y) and front-back (anteroposterior) axis (Z). To calculate Frank's leads X, Y and Z using the standard leads system, Electrocardiography (ECG) is currently the most widely used method of sensing electrical activity in the human heart. Vectorcardiography (VCG) is an investigation method that was previously compared to ECG several times and was evaluated as a useful investigation method. It achieved a higher sensitivity for the detection of hypertrophy as well as ischaemic heart disease. Three leads scanned in three mutually orthogonal axes (vertical, transversal, and sagittal) are used for VCG measurements, but this is not commonly used in clinical practice due to the more complex interpretation of the recordings. Mathematical transformations can be made between ECG and VCG leads. Previously, ECG transformations from VCG leads were used, but later only 12-lead ECG spread and VCG leads were derived from ECG leads instead of measurements. These transformations are based on transformation coefficients that have been defined by various authors . For example, the authors used thoracic models to obtain the coefficients, or, based on the similarity of one of the ECG leads, they determined the orthogonal lead. Transformation methods have also been developed based on a regression approach for multiple recordings of simultaneously measured ECG and VCG. VCG is a diagnostic and less specific method than the standard 12-lead ECG measurement . This method can be measured using several different lead systems. In clinical practice, Frank’s orthogonal lead system is the most widely used. It is measured using three orthogonal leads described by Frank, which measure cardiac activity with the same sensitivity. The problem of needing to connect multiple electrodes to measure both ECG and VCG was solved by synthesis from the currently recorded ECG leads. Compared to ECG, VCG has been recognized as a very useful investigative clinical method for cardiac activity sensing , the detection and localization of acute myocardial infarction, right ventricular hypertrophy, and Tawar arm blockade. Despite all the benefits of VCG, ECG is increasingly being used. VCG recognizes three planes, sagittal, transversal, and frontal. The frontal one is located between the XY leads, the transverse one between the XZ leads, and the sagittal one between the YZ leads
