The primary reason that an increase in heart rate (100 bpm) detrimental to the client with a myocardial infarction (MI) is that:
Decreased coronary artery perfusion due to decreased diastolic filling time will occur, which will increase ischemic damage to the myocardium. This is because during tachycardia, the time for diastolic filling is reduced, thereby limiting the blood supply to the coronary arteries. This decreased perfusion leads to worsening ischemia and potentially larger infarct size in a patient with a myocardial infarction.
