Forward electrocardiography based on measured data

A simulation study on the ECG is performed using the measured thorax geometry of a healthy subject and a measured ventricular activation sequence, known from the literature. Resulting QRS waveforms are compared with those actually measured on the subject. An adapted activation sequence is derived which, while differing only a small amount from the measured data, produces ECGs more closely resembling the ones measured on the subject. Measurements of the QRS complexes of the healthy subject have been performed using a 64-channel body-surface mapping system
