---|---|
Nursing assessment with anti-arrhythmic drugs | Bp, HR, baseline EKG |
Adverse Effects of class II anti-arrhythmic drugs | bronchospasm, dyspnea, CNS effects, hypotension, bradycardia, AV block, arrhythmias, alterations in peripheral perfusion, GI problems, loss of libido, decreased exercise tolerance, alterations in blood glucose levels |
Contraindications of class II anti-arrhythmic drugs | Sinus bradycardia, AV block, cariogenic shock, HF, asthma, respiratory depression, pregnancy and lactation |
IV lidocaine (Class Ib anti-arrhythmias) Indications | management of acute ventricular arrhythmias during cardiac surgery or MI |
IV lidocaine Actions | decreases depolarization, decreasing automaticity or the ventricular cells, increases ventricular fibrillation threshold |
IV lidocaine Contraindications and Cautions | Allergy, HF, hypotension, bradycardia or heart block unless an artificial pacemaker, shock, electrolyte disturbances, caution should be used in pts with renal or hepatic dysfunction, cross placenta & enter breast milk, should not be used during lactation |
IV lidocaine Adverse Effects | Dizziness, light-headedness, fatigue, arrhythmias, cardiac arrest, nausea, vomiting, anaphylactoid reactions, hypotension, vasodilation |
IV Amiodarone (Class III Antiarrhythmics) Indications | Treatment of life-threatening ventricular arrhythmias |
IV Amiodarone Actions | Acts directly on heart muscle cells to prolong depolarization and the refectory period, increasing the threshold for ventricular fibrillation, also acts on peripheral smooth muscle to decrease peripheral resistance |
IV Amiodarone Adverse Effects | Malaise, fatigue, dizziness, HF, cardiac arrhythmias, cardiac arrest, constipation, nausea, vomiting, hepatoxicity, pulmonary toxicity, corneal micro deposits, vision changes |
Class III anti-arrhythmic drug actions | Beta-adrenergic blockers that block beta-receptors causing a depression of phase 4 of the action potential |
