A major source of measurement error is the inability of the endocardial electrodes to maintain stable contact with heart tissue. Systolic motion introduces about a 5mm translational and rotational error and respiration adds another 5 mm. That's the more important problem to first solve. Biosig will just be garbage in garbage out unless the former issue is dealt with.
