treats atrial and ventricular tachydysrhyhmias -adverse effects: dysrhythmias, blood disorders, lupus like syndrome, vomiting, diarrhea, prolonged QT interval, - Procainamide (Pronestyl) -Class Ib -block sodium channels -accelerate repolarization -increase or decrease APD -used for atrial and ventricular tachydysrhythmias caused by digitalis toxicity or prolonged QT interval - Phenytoin -used to treat ventricular tachydysrhythmias -raises ventricular fibrillation threshold -can cause twitching, convulsions, confusion, respiratory depression, hypotension, bradycardia, dysrhythmias - Lidocaine (Xylocaine) -more pronounced effect on blocking sodium channels -class Ic -has little effect on APD or repolarization -used for severe ventricular dysrhythmias -first line drug in treatment of afib-negative inotropic effect and depresses left ventricle -contraindicated in hypersensitivity, cardiogenic shock, second or third degree AV block and non-life threatening dysrhythmias - Flecain
