The primary reason that an increase in heart rate (100 bpm) detrimental to the client with a myocardial infarction (MI) is that:
A. Stroke volume and blood pressure will drop proportionately
B. Systolic ejection time will decrease, thereby decreasing cardiac output
C. Decreased contractile strength will occur due to decreased filling time
D. Decreased coronary artery perfusion due to decreased diastolic filling time will occur, which will increase ischemic damage to the myocardium
