Measure the QRS from the onset of the complex to the end of the S wave A normal QRS complex should be less than 0.12s (3 small squares). QRS complexes are abnormally wide in the presence of bundle branch block (see Ch. 2), or when depolarization is initiated by a focus in the ventricular muscle causing ventricular escape beats, extrasystoles or tachycardia (see Ch. 3). The QRS complex represents the depolarization (activation) of the ventricles. It is always referred to as the “QRS complex” although it may not always display all three waves. Prolonged QRS Interval.

The Q wave is a short downwards deflection, the R wave a conspicuous upwards stroke and the S wave a return to below the level of the base-line. Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005 The normal duration (interval) of the QRS complex is between 0.08 and 0.10 seconds — that is, 80 and 100 milliseconds. When the duration is between 0.10 and 0.12 seconds, it is intermediate or A record of the electrical activity of the heart showing certain waves called P, Q, R, S, and T waves. The Q, R, S, T waves are associated with contraction of the ventricles, the lower two chambers of the heart.

QRS Complex. The QRS complex duration is measured from the beginning of the Q wave to the end of the S wave. Normal duration is up to 0.04 second in cats, 0.05 second in small dogs, and 0.06 second in large dogs. A QRS complex that is too wide indicates left ventricular enlargement (Figure 4-27).
