ECG plays an important role in detection ... Several markers of atrial or atrioventricular nodal abnormalities such a intervals of P wave, PR, terminal velocity, P morphology, P area and signal ...

Because the atrial rate is so fast, and the action potentials produced are of such low amplitude, P waves will not be seen on the ECG in patients with atrial fibrillation. At times, the P wave ...

Thus, the P wave height becomes larger. The ECG criteria for diagnosing right atrial enlargement (RAE) are as follows: The P wave amplitude in lead II > 2.5 mm, or The upward deflection of the P ...

pathological Q-waves, left axis deviation and conduction delays and findings suggestive or diagnostic of primary electrical diseases such as long QT syndrome and Wolff-Parkinson-White syndrome. The ...
