Cardiac 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 b lood 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 Heparin is given for A fib- will cause pooling that will lead to clotting and can cause PE or stroke
