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.
I believe the answer is A. Don't trust me though, lol.
Answer:
Make sure you get the right diagnosis and treatment to get rid of it fast. Diabetes, Eye Health, Heart Disease, Lung Disease, Orthopedics, Pain Management. The condition can also cause wheezing and make it hard to catch your breath. Drug classes that may be used to treat chronic bronchitis/COPD include: Antibiotics to treat worsening coughs, breathlessness, and mucus production caused by infections. Anti-inflammatory drugs, such as corticosteroids (also called steroids), to reduce swelling and mucus output. Taking over-the-counter medications such as aspirin, acetaminophen, or ibuprofen can help relieve symptoms of bronchitis, such as fever, headache, and aches and pains. Aspirin should not be given to children or teenagers, unless advised by a doctor, due to the associated risk of Reye's syndrome. <em>Have a Great Day!</em>
