What is a P wave in an EKG?

In: Health, Cardiovascular Health, Medical Technologies [Edit categories]

Answer:

p-wave is a wave of depolarization that spreads from the SA node throughout the atria, and is usually 0.08 to 0.2 seconds (80-200 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 and the bundle of His.
