In the absence of disease ... that the atrial rate is between 400 and 600 bpm. This ECG strip shows AV dissociation, meaning the P waves (indicating atrial activity) are at a different rate ...

These ECG voltage attenuations are of extracardiac mechanism, and impact the amplitude of QRS complexes, P-waves, and T-waves, occasionally resulting also in shortening of the QRS complex and QT ...
