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.

Is the p wave part of the cardiac cycle?
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 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
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.
Why is the baseline flat following a U wave?
U is recovery wave. After recovery wave the base line is flat, as their is no electrical activity till P wave appears.
What initiates the p wave?
cardiac cycle
Is the p wave part of the 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
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.
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 happens between the p wave and the s wave if the distance gets longer?
since the p wave is faster it will be ahead of the s wave even though they start at the same place.
What happens to the ground when a p wave passes?
you should know. It is your homework.
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 happens to p-waves when they strike the inner core.?
When the P wave strikes the inner core it bends and goes in a different direction.
What happens to p-waves when they strike the inner core?
When the P wave strikes the inner core it bends and goes in a different direction.
Does the p wave in an ekg indicate atrial depolarization?
No it does not. Atrial repolarization is generally not visible on the telemetry strip because it happens at the same time as ventricular depolarization (QRS complex). The P wave represents atrial DEpolarization (and atrial systole). Atrial repolarization happens during atrial diastole (and ventricular systole).
