QRS Interval
The QRS Interval represents the time it takes for the ventricles to depolarize.
The QRS interval portrays the health of the ventricles and ventricular conduction system, specifically the HIS Purkinje System.
The QRS interval begins at the first deflection after the PR interval which will be a Q or R wave.
The QRS interval ends after the last deflection which could be a R, S, R-Prime wave.
A normal QRS interval is 0.10 seconds or less.
