It is a small wave seen at the beginning of each cardiac cycle It can sometimes have abnormalities in morphology or timing that can be indicative of significant clinical pathology.[1] an. The p wave provides crucial information about atrial depolarization and heart rhythm disorders
Electrocardiograms (EKGs/ECGs): Evaluating P Waves - Stepwards
In this article, we will explore the complexities of the p wave, its importance and its implications in ekg analysis.
The p wave is the first positive deflection on the ecg it represents atrial depolarisation normal duration
< 0.12 s (< 120ms or 3 small squares) Your ecg's p wave shows you how long it takes for your heart's upper chambers, or atria, to squeeze during each heartbeat Abnormal p waves often indicate that either there's an abnormality in your atria, or that your heartbeats start from a place in your heart other than your heart's sinus node Missing p waves can also be a sign of abnormal heart rhythms, like atrial fibrillation.
The p wave and pr segment is an integral part of an electrocardiogram (ecg) It represents the electrical depolarization of the atria of the heart It is typically a small positive deflection from the isoelectric baseline that occurs just before the qrs complex
