The officer is given the opportunity to freeze the action by stepping in to investigate. 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).
Therefore, each small 1-mm square represents 0.04 sec (40 msec) in time and 0.10 mV in voltage. Because the recording speed is standardized, one can calculate the heart rate from the intervals between different waves. P wave (atrial depolarization) The P wave represents the wave of depolarization that spreads from the SA node throughout the atria, and is usually 0.08 to 0.10 seconds (80-100 ms) in duration. The brief isoelectric (zero voltage) period after the P wave represents the time in which the impulse is traveling within the AV node (where the conduction velocity is greatly retarded) and the bundle of His.
