HR Controlled by autonomic NS
Contractility Intrinsic ability to contract
Preload End diastolic volume; Amount of stretch in myocyte prior to contraction; Depends on venous BP and rate of return
Afterload Pressure needed in ventricles to eject blood; Depends on pulomary artery pressure (right) or aortic pressure (left); Chronic Increased afterload with lead to ventricular hypertrophy
Arterial Pressure Peripheral resistance x cardiac output

Beta Blockers (Atenolol, Propranolol: see notes) action Block stimulations of beta adrenergic receptors-decreases BP and HR
Beta blocker side effects Fatigue, weakness, bronchospasm, bradycardia, HF, pulmonary edema, hypotension, GI upset, ED, rash, Stevens-Johnson, arthralgia, muscle cramps, paresthesia drug induced lupus
Beta blocker interventions Monitor BP/pulse/EKG, monitor for signs of HF, monitor compliance, assess angina, Monitor for overdose- treat with modified trendelenberg, IV fluids, vasopressors, glucagon; Hold if pulse <50. PO, IV
