Study Review Test ATI EKG With 100 % Correct Answers. normal sinus rhythm ECG A. PR interval length B. QRS length C. QT interval - CORRECT ANSWER A. 0.12-0.20 seconds B. 0.08-0.12 seconds C. 0.35-0.43 seconds A-flutter - CORRECT ANSWER rapid regular atrial depolarization that produces sawtooth ECG pattern treatment: CCB/BB to reduce HR anticoagulant ibutalide (dysrhythmic for A-flutter) cardioversion radiofrequency catheter ablation (destruction of tiny parts of heart that produce extra conduction) when to treat bradycardia (HR less than 60) - CORRECT ANSWER only if pt is symptomatic meds that treat bradycardia (2) - CORRECT ANSWER atropine isoproterenol non-med management for bradycardia - CORRECT ANSWER pacemaker meds that manage A-fib, SVT, and V-tach *w/ pulse* (3) - CORRECT ANSWER amiodarone adenosine verapamil non-med management for A-fib, SVT, and V-tach *w/ pulse* - CORRECT ANSWER synchronized cardioversion meds that manage V-fib and V-tach *without pulse* (3) - CORRECT ANSWER amiodarone lidocaine epinephrine non-med management for V-fib and V-tach *without pulse* - CORRECT ANSWER defibrillation what should be done if pt loses pulse during synchronized cardioversion - CORRECT ANSWER immediately begin unsynchronized defibrillation synchronized cardioversion function - CORRECT ANSWER delivers counter-shock to the heart synchronized to QRS complex used for A-fib, SVT, and V-tach w/ pulse defibrillation function - CORRECT ANSWER deliver unsynchronized counter-shock to the heart, stopping all electrical activity so SA node can reestablish rhythm used for V-fib and V-tach without pulse premature ventricular contraction (PVC) ECG - CORRECT ANSWER wide QRS complex and no P waves--ventricles contract before atria hyperkalemia ECG changes (4) - CORRECT ANSWER tall T-wave flat P-wave
