Heart Disease caused most deaths
<span>When someone tries to lose weight and he/she does a
lot of exercise and eats healthy food, but that does not have results, the
reason is slow metabolism. One of the most important things for good metabolism
is to drink a lot of water (cold water is better for metabolism than warm). It
is also important to have at least three meals during the day, and not to eat after
dinner. It means that, if you eat after 18 or 19h, it will have bad effect on
your metabolism and health. Good sleep is also important for metabolism: you
should go to sleep around 22 or 23h. Stress is also one of the things which
slows our metabolism...</span>
My best guess would be C. Assessing a patient's level of compliance with past medical advice. You want to know if they have followed medical advice prior because if they haven't, you would just be wasting your breath.
Answer:
a. QRS
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
The QRS complex represents the time necessary for the impulse to travel through the bundle of His, the bundle branches, and the Purkinje fibers to complete ventricular activation or contraction, known as ventricular depolarization. QRS is simply a combination of the Q-wave, R-wave and the S-wave which represents electrical impulses.
