The MLR methodology, however, selects three best differential leads that can be
measured with wireless electrodes and transmitted in a wireless method to a
personal terminal. In the case of PCA, the transformation matrix is defined by PCs,
while in the case of MLR the transformation matrix is composed of the coefficient
vectors. The transformation matrix is applied on the measurements from the leads
selected by the algorithm to reconstruct the 12-lead ECG.
Both approaches were verified on the same input MECG that contained a single
supraventricular extrasystole. It can be concluded that the reconstructed and target
12-lead ECGs show good agreement throughout all 12-leads. We have confirmed
with several additional verifications of normal ECGs in sinus rhythm that the
proposed PCA and MLR methodologies provide even better agreement with the
target 12-lead ECGs.
We plan to verify and evaluate the proposed approaches on even more test cases,
in order to investigate their diagnostic ability in more details. The wireless
approach, supported by MLR, has an important future in the field of patient
monitoring, due to the fact that patient mobility and comfort are increased.
Hopefully, our work will contribute to the penetration of the WSN technology into
the field of the electrocardiography.
