Peaked T waves best seen in the precordial leads, shortened QT interval and, sometimes, ST segment depression. Widening of the QRS complex. This usually requires a potassium level of 6.5 or ...
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 ...
