PPT-Cardiac Arrhythmias and Conduction Abnormalities

Andrew P Wilper MD Goals and Objectives Diagnose common cardiac arrhythmias Discuss importance of and indications for anticoagulation in atrial fibrillation Diagnose common cardiac conduction abnormalities. ARRHYTHMIA. 2. 2. CLINICAL INCIDENCE. 80% cardiac arrhythmia → after M.I. 50% cardiac arrhythmia → during anesthesia. 25% cardiac arrhythmia → treatment with digitalis . Cardiac arrhythmia need to be treated when serious haemodynamic derangement expected. Clinical Scenario.
