Page 15, Cardiac Performance, Dr. D. Penney



Table 2.02 lists all the factors which influence stroke volume, heart rate as it affects the time available for diastolic filling and the development of preload, static muscle contraction acting to increase vascular resistance and ventricular afterload, arrhythmias and tachycardias as they affect the efficiency of ventricular filling and emptying, cardiac hypertrophy as it affects diastolic compliance and contractility, etc.

Preload, afterload, contractility, heart rate and cardiac hypertrophy together all influence cardiac output.
