Unlike probable cause that uses a reasonable person standard, reasonable suspicion is based upon the standard of a reasonable police officer. 1  Probable Cause Arrests vs. Arrest Warrants.

medical Definition of P wave : a deflection in an electrocardiographic tracing that represents atrial activity of the heart â compare qrs complex, t wave Seen and Heard What made you want to look up P-wave? Please tell us where you read or heard it (including the quote, if possible).
P wave-the arch preceding the QRS complex. Q wave-the first negative (downward) deflection of the complex. In some leads, it will not be present. In some cases, the complex begins with an R wave.R wave-the first positive (upward) deflection of the QRS complex.RS-the complex represents the depolarization of the ventricles. This is followed by an isoelectric segment. T wave-this represents ventricular repolarization. Atrial Contraction-the atria mechanically contract starting at the beginning of the P wave, until the beginning of the QRS complex.
