Events in the cardiac cycle (Fig. 18-8). 2. Pressure gradients and their role in chamber filling and emptying (Fig. 18-10). 3. Heart sounds and the electrocardiogram. 4. Ventricular pressure curves. Frank-Starling (Fig. 18-2). 5. Preload and afterload (Fig. 18-4). II. You will have learned the material when you can: 1. Understand what the figures mean in terms of the normal cardiac cycle.

Unformatted text preview: III. Sample Problems: 1. Why is there an isovolumic (isometric) part of the ventricular pressure curves? 2. Why does the diastolic pressure in the aorta not fall to zero? 3. At what point in the cardiac cycle is the heart doing the most work? 4. How would an increase in end diastolic arotic pressure affect the duration of isovolumic contraction? 5. How would less elasticity of the ventricular wall affect ventricular filling during diastole? file:///C|/WINWORD/COURSES/31107/Lec21-07.htm8/15/2007 10:24:08 AM...
