and regional delay in conduction were determined from ECGi and were used as surrogates for spatial heterogeneities in repolarization and depolarization. The researchers found that after exertion ...

Depolarization was evaluated by SAECG, and repolarization was evaluated by QT dispersion measurements. At 40Hz high-pass filter SAECG, noise level was 0.39±0.07μV in group I, 0.46±0.14μV in ...
