29 sty 2022 · Normal P wave axis is between 0° and +75°. P waves should be upright in leads I and II, inverted in aVR. Duration. < 0.12 s (<120ms or 3 small squares) Amplitude. < 2.5 mm (0.25mV) in the limb leads. < 1.5 mm (0.15mV) in the precordial leads.

The P-wave, PR interval and PR segment. ECG interpretation traditionally starts with an assessment of the P-wave. The P-wave reflects atrial depolarization (activation). The PR interval is the distance between the onset of the P-wave to the onset of the QRS complex.
The 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.
28 lut 2011 · P waves. The next step is to look at the P waves and answer the following questions: 1. Are P waves present? 2. If so, is each P wave followed by a QRS complex? 3. Do the P waves look normal? – check duration, direction and shape. 4. If P waves are absent, is there any atrial activity? Sawtooth baseline → flutter waves
Sinus rhythm (which is the normal rhythm) has the following characteristics: (1) heart rate 50–100 beats per minute; (2) P-wave precedes every QRS complex; (3) the P-wave is positive in lead II and (4) the PR interval is constant.
