Abstract

Method for estimating beat-by-beat cosRT angle from the 12-lead exercise electrocardiogram (ECG) measurement is presented. Method uses principal component regression to generate ECG waveform model, and uses this model to denoise QRS complexes and T-waves. In addition two different methods for synthetizing vector ECG from the conventional 12-lead measurement are compared. First method synthetize vector ECG by using inverse of the Dowers matrix and second method produces vector ECG by using singular value decomposition. Results indicate that vector ECG synthesized using Dowers matrix gives more comparable results for healthy subjects. Beat-by-beat cosRT estimation revealed that due to respiration angle values can vary as much as 70 degrees, because of changes to electrode positions and volume conduction model of the torso. Thereby presented method for beat-by-beat estimation of the cosRT angle can improve reliability of this parameter.
