To determine whether there is a delay in impulse conduction through the ventricles, the nurse will measure the duration of the patient's: A) p wave B) q wave C) pr interval D) qrs complex D) qrs complex (the qrs complex represents ventricular depolarization. The p wave represents the depolarization of the atria. The pr interval represents depolarization of the atria, av node, bundle of his, bundle branches, and the purkinje fibers. The q wave is the first negative deflection following the...
