How the model works: supply = flow capacity of the artery (falls steeply above about 70 percent stenosis) × share of each minute in diastole × hemoglobin ÷ 14. Demand = heart rate ÷ 70 × systolic pressure ÷ 120. A beta-blocker lowers rate, pressure and contractility; nitroglycerin lowers preload and dilates the coronary a little. When supply ÷ demand falls below 1, the monitor shows ST depression.
Questions come from a bank of written items plus generated cases with new numbers each time, so you can practice as long as you like. Answer choices are shuffled every time.
