Document Summary
Medsurg chapter 26: management of patients with dysrhythmias and conduction problems. Disorders of formation or conduction of electrical impulses within the heart. Potentially can alter blood flow and cause hemodynamic changes. Often the trigger for looking for a problem is hemodynamic changes. Treatment is based on frequency or severity of symptoms. Dysrhythmias are named off of origin of impulse and mechanism of formation or conduction involved. Located near the superior vena cava in the right atria. Slows electrical impulses giving the atria time to fill with blood. The impulse is moving through and the muscle captures. Sa node av node atrial ki(cid:272)k bundle of his purkinje fi(cid:271)ers systole diastole. Conduction: the electrical impulse travels from the sa node to the av node. Reflects the function of the hearts conduction system. Represents the electrical impulse starting in the sa node and spreading through the atria. Measured from the beginning of the p wave to the beginning of the qrs complex.
