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.

For the patient with breathing problem, first aid can be performed
Firstly Check the person's airway, breathing, and pulse. If necessary, begin CPR.
Loosen any tight clothing.
Help the person use any prescribed medicine (such as an asthma inhaler or home oxygen).
Continue to monitor the person's breathing and pulse until medical help arrives. DO NOT assume that the person's condition is improving if you can no longer hear abnormal breath sounds, such as wheezing.
If there are open wounds in the neck or chest, they must be closed immediately, especially if air bubbles appear in the wound. Bandage such wounds at once.
A "sucking" chest wound allows air to enter the person's chest cavity with each breath. This can cause a collapsed lung. Bandage the wound with plastic wrap, a plastic bag, or gauze pads covered with petroleum jelly, sealing it on three sides, leaving one side unsealed. This creates a valve to prevent air from entering the chest through the wound, while allowing trapped air to escape from the chest through the unsealed side.
