P r wave

Webb17 dec. 2012 · The P wave in II is pyramidal in shape with somewhat rounded apex. Its limbs are smooth with no irregularities. The duration of P wave is 0.08-0.10 sec, but is no greater than 0.11sec. The maximal normal amplitude is 2.5mm, but the normal P wave is usually no greater than 2 mm. THE P WAVE FORM IN LEAD V1. A P wave (primary wave or pressure wave) is one of the two main types of elastic body waves, called seismic waves in seismology. P waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph. P waves may be transmitted through gases, liquids, or solids.

WebbP Wave. It is important to remember that the P wave represents the sequential activation of the right and left atria, and it is common to see notched or biphasic P waves of right and left atrial activation.

It may be defined, for example, as R wave of less than 2–4 mm in leads V 3 or V 4 and/or presence of a reversed R wave progression, which is defined as R in V 4 < R in V 3 or R in V 3 < R in V 2 or R in V 2 < R in V 1, or any combination of these.

When the amplitude of atrial repolarization is low, the segment between the end of P and the onset of the QRS complex is, for practical purposes, horizontal.
