QRST Wave - QRST

Japanese: QRST 波 - きゅーあーるえすてぃーは
QRST Wave - QRST

…Each wave is given the universal name P or QRST. Since P waves originate from excitation of the atria and QRST waves originate from excitation of the ventricles, clues can be obtained from waveform changes (shape and size), phase shifts, the presence or absence of each wave, and the relationship between each wave. The waveform and wave height vary considerably depending on the relative positions of the generator (heart) and the lead-out electrode via the volume conductor, the distance from the excited site, or the lead-out method. …

*Some of the terminology that refers to "QRST waves" is listed below.
