Yes - On an ECG the P wave is the first wave of the cardiac cycle. It represents the Sinoatrial node which is the natural pacemaker of the heart firing and causing the atria to contract in order to fill the ventricles.

What happens in the cardiac cycle after the p wave?
The T wave on an ECG reading is the last wave in the cycle, and it represents the repolarisation of the heart. This means that the ventricles have just contracted sending blood around the body, and the heart is now 'resetting' itself ready for the next cycle.
What happens in the cardiac cycle immediately before P wave?
The P wave on an ECG occurs when the sinoatrial node which is the hearts natural pacemaker fires causing the atria to contract. The period just before this when there is no electrical activity is the hearts 'resting' period between beats when the muscles are relaxed giving the atria a chance to refill with blood.
Why is the R wave taller than the P wave on the ECG graph cycle?
The QRS complex is normally larger than the P Wave because depolarization of the larger muscle mass of the ventricles generates more voltage than does depolarization of the smaller muscle mass of the atria
What part of the ECG records atrial contraction?
ECG records electrical activity and not mechanical, hence it has nothing to do with contraction. But P wave represents atrial depolarization.
The portion of the ECG that corresponds to atrial depolarization is the?
The portion of the ECG that corresponds to atrial depolarization is called the P wave. The P wave is the first wave on the ECG.
What initiates the p wave?
cardiac cycle
How does the P wave the qrs complex and t wave relate to the electrical and mechanical evemts of the cardiac cycle?
its related to the dialysis

Immediately before the P wave?
The electrical milestone event that occurs at the P wave of the cardiac cycle of the EKG is atrial depolarization. The upward stroke is right atrial depolarization, and the downward stroke is left atrial depolarization. Normally, this lasts for no more than 0.11 sec.
What does the p in p stand for?
Primary Wave and the other is Surface wave (S wave) in case anyone is wondering. Both are part of earthquakes.
What part of the ECG complex represents the atrial depolarization?
The P wave.
What part of an ecg do atria contract?
Atrial depolarization occurs at the P wave. The atrial contraction occurs at the peak of the wave at the influx of calcium ions to prolong depolarization.
Why is the R wave taller than the P wave on the ECG graph cycle?
The QRS complex is normally larger than the P Wave because depolarization of the larger muscle mass of the ventricles generates more voltage than does depolarization of the smaller muscle mass of the atria
Which is faster an s-wave or a p-wave?
P-Wave
What is a p wave?
A p wave is the primary or compression wave in a seismic wave. it's wavy
Is surface wave faster then a p wave?
no a p wave is faster than s wave
