- B. Damage to the myocardium
- C. Disorder of impulse conduction in the myocardium
- D. Cardiac overload due to increased vascular resistance
- E. Cardiac overload due to increased blood volume
Hint
Ask what long-standing high arterial pressure does to the work the left ventricle must do on each beat before it eventually fails.
