Normal cardiac output- Normal cardiac output is 60-100 beats per minute. If below 60 is brady cardia and the patient is at risk for poor perfusion. Cardiac output is defined as the amount of blood pumped from the left ventricle each minute. Remember that arrhythmia is a deviation from a normal rhythm and a dysrhythmia is a disturbance in the normal rhythm. 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. A fib and A flutter
