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.
P wave-the arch preceding the QRS complex. Q wave-the first negative (downward) deflection of the complex. In some leads, it will not be present. In some cases, the complex begins with an R wave.R wave-the first positive (upward) deflection of the QRS complex.RS-the complex represents the depolarization of the ventricles. This is followed by an isoelectric segment. T wave-this represents ventricular repolarization. Atrial Contraction-the atria mechanically contract starting at the beginning of the P wave, until the beginning of the QRS complex.
