It is a small wave seen at the beginning of each cardiac cycle The p wave provides crucial information about atrial depolarization and heart rhythm disorders 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 It can sometimes have abnormalities in morphology or timing that can be indicative of significant clinical pathology.[1] an.
