How does our heart work ?
This
is still an interesting topic upon which researchers, doctors continue to ask
more and more questions. Thanks to the video of McGraw Hill, we can
understand what systole and diastole are. They are instrumental in the good
function of our heart. If they fail to meet the needs of our body in blood
volume and oxygen, we are at risk of developing heart failure a condition
better known under the name of congestive heart failure (CHF).
Many
signs can herald this impending condition such as: anxiety, weight gain,
dyspnea or a sensation of quick filling after eating a little bit and
paroxysmal nocturnal dyspnea. Respiratory discomfort is mostly present, because
the mismatching of the couple diastole systole (blood ejection due to
ventricular contraction and ventricular relaxation)reduces the movement
of the fluids, first at all in the respiratory system before going further to
the liver, the upper part of the body and the limbs, to mention a few
