After the discussion of the ultimate high fiber foods, letâs take a look at just what fiber is. First, it is important to note that fiber only occurs in fruits, vegetables, and grains. It is part of the cellular wall of these foods. Diets high in fiber may reduce the risk of obesity, heart disease, and diabetes.
The P wave in the ECG represents atrial depolarization, which results in atrial contraction.ormally the right atrium depolarizes slightly earlier than left atrium since the depolarization wave originates in the sinoatrial node, in the high right atrium and then travels to and through the left atrium.
Plane P-wave. Representation of the propagation of a P-wave on a 2D grid (empirical shape). P-waves are a type of body wave, called seismic waves in seismology, that travel through a continuum and are the first waves from an earthquake to arrive at a seismograph.ypical values for P-wave velocity in earthquakes are in the range 5 to 8 km/s. The precise speed varies according to the region of the Earth's interior, from less than 6 km/s in the Earth's crust to 13 km/s through the core.
