:
The ECG waveform has a predictable shape, and professional
ECG analysts give each part of that shape a letter-name. The
names go in alphabetical order across the waveform, from
P to U.
The most visible part of the waveform is the combination of
the Q, R, and S waves, technically called the QRS complex.
Most people think of this shape when they think of an ECG.
This sample waveform is highly simplified and unnaturally
pristine. It is presented only as a theoretical example from
which to learn to identify the waveform components in a real
ECG.
See Chapters 1, 2, and 3 of Huszar's Basic Dysrhythmias (see
Bibliography).
