- increased strength of cardiac contraction -> increased stroke volume -> increased cardiac output


Major Side Effects Nursing Intervention
digoxin, digitoxin low therapeutic index!!! (= high risk of toxicity -take apical pulse for full minute, monitor ECG -don't give if hearth rate is low (<60bpm) -monitor potassium levels (risk of enhanced toxicity)
dobutamine, dopamine hypertension, headache, angina -alert physician if arrhythmia, chest pain or dyspnea occur
extracardiac: -nausea, abdominal pain -fatigue -confusion, disorientation -color misperception: yellow halos cardiac: - AV block, arrhythmias Toxicity of DIGITALIS is enhanced by: >hypokalemia >alkalosis >hypoxia
