- The P Wave in EKGThe P wave is the first deflection of the cardiac cycle seen on an EKG. It represents the electrical activity associated with atrial depolarization. The normal P wave is a low amplitude, vertical, rounded wave, resembling a gentle hill, which is continued immediately from the QRS complex.
- P Wave ECG Interpretation #301 - Practical Clinical SkillsThe P wave represents atrial depolarization. This wave is generated by an impulse from the SA node in the right atrium and is conducted across the atria. In a normal EKG, the P-wave precedes the QRS complex. It looks like a small bump upwards from the baseline.
- P-wave, PR interval, PR segment: physiology, criteria & ECG ...The P-wave is virtually always positive in leads aVL, aVF, –aVR, I, V4, V5 and V6. It is negative in lead aVR. The P-wave is frequently biphasic in V1 (occasionally in V2). The negative deflection is normally
- P wave - StatPearls - NCBI Bookshelf - National Center for ...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 ...
