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 ...

What does the SA node initiate - - P wave (if none, SA not responsible for electrical conduction) (atrial depolarization) What does the QRS complex represent? - ventricular depolarization (vent contraction) (none=no pulse) (don't see atrial repolarization but it occurs, as it is not the strongest thing to occur) What does the U wave indicate? - indicates hypocalemia, not conductio issue it would be seen with electrolyes (digoxin) Is it normal to not see part of the Q, R, or S complex -...
