Question

Scenario: One human, who is much heavier than the others, seems to be showing signs of what Vegan’s experience when their diets are high in monosaccharides and saturated fats.  Studies of Vegan circulation indicate that this leads to narrowing of artery walls as plaque accumulates over time inside the lumen of the artery, and these arteries become hardened and lose some of their elasticity.  This human then appears to have a mild heart attack right there in the Vegan spacecraft!  X-rays show that the heart attack caused some of the heart tissue to die and this prevents impulses in the heart from reaching the AV node.

a. Predict the effect on systolic and diastolic blood pressure.

b. Predict the effect on the EKG trace. Present both in a drawing of the trace and explain how/why it is different from the normal trace.
