Question

Quizplus · Accepted Answer

The patient has impaired ventricular functioning because a portion of the myocardium has died due to ischemia.
Impaired ventricular function is due to damage to the myocardium; it is not due to electrolyte imbalance.
There was stress on the heart,but the impaired functioning is due to myocardial damage secondary to ischemia.
The impaired ventricular dysfunction is due to myocardial cell death,not hypertrophy.
