WebbNeither the intermittence of Q wave in V2 on repeated ECGs nor the absence of septal Q waves was useful in distinguishing between those with and without coronary heart disease. Conclusions: This ECG finding should be interpreted as a nonspecific QRS abnormality with multiple possible causes. WebbNote:To label a negative wave as “q” or “s” we must have a “R” wave. Sometimes there is a QRS complex which does not have a positive deflection and has only a negative deflection, so we will label it as “QS” or “qs” depending upon the amplitude of a wave.
