Figure 1: Mechanisms of spreading depolarization in the neuron. Figure 2: Normal (spreading hyperemia) and inverse (spreading ischemia) function of the neurovascular unit in response to spreading ...

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, ...

Phase 3 ventricular repolarization is characterized on the ECG as the T wave. The time between the beginning of ventricular depolarization (Q wave) and the end of the T wave is the Q-T interval.
