The QRS complex begins as a downward deflection, the Q wave. A Q wave is always a negative waveform. The Q wave begins when the ECG leaves the isoelectric line in a downward direction and continues until it returns to the isoelectric line. The Q wave represents depolarization of the interventricular septum, which is activated from left to right.
