Wave: a deflection of the ECG line due to any change in the electrical activity of the heart (e.g., P wave, T wave) Positive (upward) deflection: the electrical impulse is moving toward the electrode Negative (downward) deflection: the electrical impulse is moving away from the electrode...

Baseline wander is a common problem in clinical practice that can occur due to loose electrodes, respiration, perspiration, body movements, or dry electrodes. Even slight degrees of baseline wander can create challenges for the accurate assessment of the ST-T wave. To correct this and increase ...
In children, the R wave width is narrower than that in adults and contains many high frequencies5. If the amplitude of the R wave is greatly reduced, the T wave then appears to be relatively increased when assessed by anesthesiologists and clinicians in the operating room. As a result, ...
