WebbThe magnitude of the resultant vector, measured in millivolts, is known as the mean QRS potential, or the mean ventricular potential. In the frontal plane, the mean QRS axis is typically between 0° and +90°, usually around +50°. The anatomical axis of the adult heart is around +55°, meaning the apex of the heart points to the lower left rib ... WebbAC Waveforms. When an alternator produces AC voltage, the voltage switches polarity over time, but does so in a very particular manner. When graphed over time, the “wave” traced by this voltage of alternating polarity from an alternator takes on a distinct shape, known as a sine wave: Figure below.
