The pr interval measures
WebbThe PR interval reflects whether impulse conduction from the atria to the ventricles is normal. The PR interval must not be shorter than 120 msec or longer than 220 msec. … WebbThe PR interval looks at the time from the onset of the impulse in the SA node through the AV node. The QRS interval measures the time of conduction from the AV node through the bundles, Purkinje fibers, and the rest of the ventricles. Other alterations in the waveforms give other information about cardiac conditions.

WebbThe Q-T interval, as its name suggests, measures the time from the start of the Q wave to the end of the T wave. This measures the time for depolarization and repolarization, or contraction and relaxation, of the heart’s ventricles. The Q-T interval is dependent upon heart rate: a faster heart rate results in a shorter Q-T interval.
