Medications for: contractility, maintaining normal blood pressure, various tachycardias, bradycardias, different degrees of AV blocks, and arrhythmias PHARM Class 1- Sodium channel blockers- electrical pulses will become slow. Used for TACHYARHYTHMIAS Class II- Beta Blockers. Beta receptors are blocked. Used for tach arrhythmias Class III- potassium channel blockers. Amiodarone. Used for V tach and V fib Class for- calcium channel blockers- diltiazem, arabamil? Given to slow ventricular rate in a fib and supra ventricular tachycardia. Adenosine/ Digoxin- Adenosine has very short half life and is given IV push and primarily used to stop supra ventricular tach Digoxin- will slow conduction through the AV node.
