However, the amplitude of the P wave is exaggerated due to the close proximity of the hypertrophied right atrial myocardium to the SA node. This is referred to as p-pulmonale since lung disease ...

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 ...

Surface waves usually have larger amplitude than the other waves and cause the most damage. A P wave is a longitudinal wave and travels the fastest. It can travel through solids and liquids.

allows for identification of rhythm or waveform abnormalities during exercise Seconds for interval and millivolts for amplitude calculations P wave: amplitude increase in inferior leads ...
