Does a Bayesian method for estimating the vectorcardiogram improve the prediction of ECG signals compared to the inverse Dower matrix method in standard, scaled, and fetal ECG recordings?
A novel Bayesian method for vectorcardiography estimation outperforms the standard inverse Dower matrix method in nonstandard patients, such as fetuses and those with altered body compositions.
Vullings et al. (2009) studied Healthy adults and fetus (n=11). Patient-tailored vectorcardiography (PTV) method vs. Inverse Dower matrix method was evaluated on Normalized Mean Squared Error (MSE) between recorded ECG signals and VCG projections. The Bayesian patient-tailored vectorcardiography method significantly outperformed the inverse Dower matrix method in predicting ECG signals for nonstandard and fetal ECG recordings.
