Discussion 3 - Coursework typeThe chest surpasss measurements should also be taken. The six chest leads are V1-V6. The records in this stage are full of life since they show the time of electric travel from one node to another. The records give the average time taken by the ventricles to recover or refill with blood.Lead I voltage is then measured with lengthiness to the electrodes amidst the right arm and the remaining leg. The records give the longest time of electric travel between the furthest limbs (Christoffels, 2009). The records should be taken for each limb with the relative nodes identified in different separate of the body. The readings taken should show the time of electric travel and the ventricle recovery.ST segment elevation in lead II, III and AVR creates some movements in the go away auricle of the heart. It causes the capsule and relaxation of the left auricle muscles as a result of an electric impulse (Surawicz, 2009). The relaxation and contraction forces blood through the valve thereby causation it to cobblers last and open. The contraction and relaxation affects the right atrioventricular valve.ST segment gallant in VI-V2 affect the left ventricle. It results in a systematic contraction and relaxation of the left ventricle. It combines a series of action relating to the contraction and relaxation of the lower part of the heart muscles. It affects the left coronary artery causing it to open and close at regular intervals. It results in the entry and expulsion of blood from the chamber that also sets the heartbeat one thousand (Katz, 2010). It also triggers a strong force that forces the blood out of the heart through the aorta.ST segment elevated in V3-V4 affects the right ventricles muscles. The opening and closing of the valve is triggered by an electric impulse that originates from the left ventricle muscles. The segment produces an electrical conduction system that controls the Purkinje fibers. The effects are caused by an i mpulse resulting from
