ABSTRACT
Myocardial ischemia, arrhythmias, and sudden death can occur during or immediately after exercise.
Cardiovascular function is under the regulatory control of the sympathetic nervous system, with sympathetic stimulation causing an increase in heart rate, force of myocardial contraction, and blood pressure. During exercise, there is a progressive rise in systolic pressure, though usually very little, if any, change in diastolic pressure. Diastolic pressure may fall slightly in younger individuals and rise in middle-aged and older individuals.
