Describe treatment of dysrhythmias correct answer: To determine if treatment is necessary, assess the patient. Then ask the following questions: Is he or she experiencing signs and symptoms of decreased cardiac output? Is the dysrhythmia potentially life threatening? If the answer to either of these questions is yes, the patient will need to treatment for the dysrhythmia. ***WE WILL DISCUSS TREATMENTS OF DYSRHYTHMIAS BASED UPON CURRENT ACLS TREATMENT ALGORITHMS CLINICAL MANIFESTATIONS ...

Rheobase - the lowest point on a strength duration curve at an infinitely long pulse duration Chronaxie time - the pulse width at twice the rheobase value. It approximates the most efficient stimulation pulse duration Charge (formula) - Charge= I(current) x T(time) Furman's formula - Energy(microjoules)= I(current)xV(voltage)xT(pulse width) Ohms law formula - Voltage(electromotive force)= I(current/flow of electrons) x R(resistance to current flow in ohms) Functional Refractory P...
