The quantity h, now known as the Planck constant, is a universal constant with the approximate value of 6.626 X 10^-34 Js. Max Planck assumed that the radiation energy is emitted in discrete packets called quanta rather than in a continuous way. The energy E of the quantum is related to the frequency Î½ by E = hÎ½. The quantity h, now known as the Planck constant, is a universal constant with the approximate value of 6.626 X 10^-34 Js.

1 Some patients with anemia have no symptoms. 2  Those that do have symptoms may. 3  feel tired, 4  become easily fatigued, 5  appear pale, 6  have a feeling of a heart racing, 7  feel short of breath, and/or. 8  have worsening heart problems. 9  Anemia can be detected by a simple blood test called a complete blood cell count (CBC).
The signs and symptoms of atrial or ventricular bigeminy may appear similar to that of other kinds of arrhythmias, but in most cases, premature contractions go unnoticed. Possible symptoms of bigeminy include: Lightheadedness; Palpitations (noticeable rapid heartbeat) Fainting or passing out; Shortness of breath; Chest pain
