This cycle is repeated continuously in coordination with SA node depolarization. Atrial depolarization (and contraction) is represented by the P wave. high plains water valley city nd

"Webb22 dec. 2016 · The P wave: This represents a contraction of the atria. This is referred to as depolarization or the squeezing effect. This electrical wave represents blood being pumped out of the atria and into the ventricles. The QRS Complex: This represents a contraction of the ventricles. This is the depolarization or squeezing of the ventricles. " - The p wave represents the contraction of the
