The PV loop labeled 1 shows the normal change in volume and pressure during the cardiac cycle of a patient. The patient undergoes treatment and the changes in the cardiac cycle are reflected in the PV loop labeled 2. What is the more likely treatment? Treatment with a drug that increases diastolic blood pressure. Treatment with a drug that activates adrenergic receptors in cardiac contractile cells of the heart. Treatment with a drug that decreases the concentration of cytosolic Calcium in cardiac contractile cells: Trestment with a drug that decreases end diastolic volume (EDV).
