The process of heart contraction stimulates by the initiation of an electrical impulse. This electrical impulse starts in the SA node.

<h3>What is the Heart contraction?</h3>

Heart contraction may be defined as a type of physiological activity that stimulates electrical impulses which are initiated by the sinoatrial node. Systole is significantly the contraction phase of the cardiac cycle.

The SA node is a small bundle of specialized cells that is remarkably located in the right atrium. The electrical activity escalates through the walls of the atria and induces them to contract. This action finally forces blood into the ventricles.

Therefore, the SA node is responsible for the initiation of impulses that stimulates heart contraction.

A patient complains of a “stabbing pain and a burning sensation” in his left foot. the nurse notices that the foot is a lighter
lyudmila [28]
The answer that best completes the statement above is this: POSTERIOR TIBIAL. Based on the nurse's assessment, stabbing pain and burning sensation is reported as the subjective cue and the skin of the foot is lighter. Given this result, this would clearly mean that the artery in the left foot is being occluded. And the artery present here is the posterior tibial artery. The stabbing pain and burning sensation being felt of the patient is a result of lack of oxygen in the area since the blood can no longer circulate.
