In an ekg what does the p wave represent
WebThe 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 … WebThe time it takes to activate the atria is represented by the P wave on the electrocardiogram (ECG). After depolarizing the atria, the impulse enters the atrioventricular (AV) node, which is located in the inferior septal region of the right atrium, where a delay occurs. This delay allows time for the atria to contract and fill the ventricles.

P wave = Atrial Depolarization: The ventricles begin to fill with blood as blood passively flows from the atria to the ventricles (see previous section). As a result, ventricular pressure starts to increase. dewitt ar post office phone numberWebThe P wave represents the depolarization of the left and right atrium and also corresponds to atrial contraction. Strictly speaking, the atria contract a split second after the P wave begins. Because it is so small, atrial repolarization is usually not visible on ECG.
