3 pacemakers of the heart - 1. SA node 2. AV node 3. bundle branch intrinsic rate of SA node - 60-100 bpm intrinsic rate of AV node - 40-60 bpm intrinsic rate of bundle branches - 20-40 bpm electrical pathway through the heart - 1. normal conduction impulse originates in the *SA Node* 2. impulse travels to *AV Node* causing atrial depolarization (contraction)

Advent Health EKG Questions and Answers Rated A Afib The impulse originates in the Atria • The Atrial rate is > 300 and unable to measure [N/A] • No discernable P waves - PRI & Atrial rhythm cannot be measured [N/A] • The Ventricular rhythm is irregular • QRS within normal limits • If the Ventricular rate is <100 the rhythm is controlled A-fib; if the Ventricular rate is > 100 the rhythm is uncontrolled A-fib • This is a chronic rhythm for some patients Treatment: controlle...

Chapter 35: Dysrhythmias | Questions, Answers and Rationales A patient admitted with syncope has continuous ECG monitoring. An examination of the rhythm strip reveals the following: atrial rate 74 beats/min and regular; ventricular rate 62 beats/min and irregular; P wave normal shape; PR interval lengthens progressively until a P wave is not conducted; QRS normal shape. The priority nursing intervention would be to a. give epinephrine 1 mg IV push. b. prepare for synchronized cardioversion. c...
