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.
The first part of the normal sinus P Wave represents depolarization of the right atrium; the second part represents depolarization of the left atrium. During the P Wave, the electrical impulses progress from the SA node through the intermodal atrial conduction tracts and most of the AV node.
